I think the old picture for saturn that is currently displayed on the page should be updated with
the new ones taken by cassini. The puplicaly released photos and captions can be found here: http://ciclops.org/view.php?id=483&flash=1
This article has been renamed after the result of a move request.
If you look closely at the bottom of the page, there's a Moon Navigator, that is supposed to allow you to navigate from the Saturn page out through all the moons, starting with Pan. While it's a good idea, I think it should be deleted,
#It's duplicated in the Saturn Template, which lists all the moons in orbital order. You can easily do the same navigation from this, if you just look for the current page in that list (it is de-linked and bolded), and click to the link immediately to its right.
I propose that it just be deleted, and possibly a note added to the Saturn template that the moons are in order.

The volume given seems to be quite a long way from other values I've encountered, and actually contradicts the maths if you calculate it using the supplied mass and density. It seems self consistant with the Earth comparison next to it, but is different to the values given in the NASA fact sheet linked at the bottom of the article.
I'd edit it myself, but I'm not entirely sure how to...

Could you elaborate more on Saturn's magnetosphere? There are at least two of its attributes I think merit some mention:
1. Since the interior is composed of liquid metallic hydrogen like Jupiter, you would expect the magnetosphere to be large and powerful like Jupiter. However, it is extremely weak--not even detectable from Earth (we did not confirm its existance until the Pioneer 11 mission). 2. The magnetic poles are nearly inline with the geographic poles--the only planet like this in the solar system.
I'm no expert on this subject, or I would edit it myself; I just thought what I read about Saturn's magnetosphere would certainly make an interesting article...

This artical states Saturn is the most distant planet visable to the naked eye but the Uranus article states it is visable to the naked eye. Red1530 00:42, 25 August 2006 (UTC)
Uranus happens to be in that awkward place where someone with 20:20 vision could see it from a good vantage point if they really know where to look, but for most people it is too faint. The fact that Uranus isn't commonly seen is shown by the fact it is one of the more modern discoveries whereas Saturn is a big bright thing, easily observed and has been since antiquity.

Many say that the OBLATENESS of Saturn was first discovered by early moon-mapper Grimaldi, but it seems that no one knows where this was actually first recorded. The oblateness of Saturn was probably the first sighted of any planet. Grimaldi's more senior colleague Riccioli mentions much that Grimaldi assisted him with in his Astronomy books and does mention difference between horizontal and vertical diameters but does any one know details of primary sources.

In the interest of article veracity, I'm curious who posted the following comment:
Recent images from the Cassini spacecraft show that Saturn's northern hemisphere is changing colors. It now appears a bright blue, similar to Uranus, as can be seen in the image below. This blue color cannot currently be observed from earth, because Saturn's rings are currently blocking its northern hemiphere. One theory is that this shocking color change is a result of colder temperatures, as the shadows cast by Saturn's rings are blocking out sunlight. This would result in the yellow clouds sinking and Saturn's deeper blue atmosphere being revealed.
Does the poster have a citation for this observation? Who has proposed a theory explaining this shocking color change? Cite? Author?
While it is true that the upper limb of the planet appears blue, this is easily explained as scattering by the upper atmosphere that is clearly visible due to the darker surrounding atmosphere. In addition, this blue color is only limited to the limb itself which is in sunlight. Why does the poster imply this effect has occured over the whole northern hemisphere? This same effect is visible in the southern hemisphere limb as well in the posted image, suggesting the blue color is not due to temperature changes.
This is an important atmospheric effect if it is real. But there is a lot about the paragraph above that makes me think otherwise.

The cause of the change is unknown — however, it is thought that this is due to a movement of the radio source to a different latitude inside Saturn, with a different rotational period, rather than an actual change in Saturn's rotation.
This assessment is not right for 2 reasons :
1- The radio sources are in the magnetosphere and not inside Saturn as stated in the sentence. The radio emissions are produced through wave-particle interactions above the polar regions (1 to 3 Saturn radii above the surface)
2- The idea that some "slippage" occurs in Saturn's interior, leading to apparent change in the radio period when the source latitude changes, is one interpretation among others, and I have to admit that it is not the most popular among the specialists. Unfortunately, the two researchers cited in the nasa page are the two main promoters of this interpretation.
I have already written some lines about this in the french wikipedia article about Cassini-Huygens. Here is a translation :
The determination of a planet's sidereal period is essential to study any physical processes associated to that planet, as this period is use to define its longitudinal coordinate system. In the case of the terrestrial planets, observing the rotation the the surface gives the sideral period. The case of the giant planets is more tricky as we can only observe the rotation rate of the highest layers of the atmospere. The rotating core is indeed deeply buried in the middle of the planet. The only phenomenon directly linked to the rotation of the core that can be observed out of the planet, is its magnetic field. The modulations induced by the magnetic field rotation on the natural planetary radio emissions is thus used as a proxy to measure the sidereal rotation period of the planet.
In the case of Jupiter, the sidereal period as been measured this way. The sidereal period has been determined with a great accuracy: 9h 55m 29.68s ± 0.08s (0.0001% accuracy) [1]. In the case of Saturn, the sidereal period was determined first with the Voyager radio data: 10h 39m et 24s (with a 0.02% relative accuracy) [2]. Using Ulysses radio data, scientists showed in 2000 that the radio period of Saturn had changed since the Voyager era [3]. These new measurements were showing periodicities 1% longer than the Voyager ones. The radio measurements obtained with the Cassini/RPWS/HFR instrument confirms the variation of the apparent radio period. Observations conducted during the 3 first years of operation around Saturn (2004-2006) seem to show that the apparent period is slowly varying (a few percents per year).
As the rotation rate of the internal core is very unlikely to vary, the scientists are trying to find a new way of interpreting the the radio modulations.What do we know about this radio emissions ? They are mainly emitted on the dayside of the magnetosphere of Saturn [4] and are strongly correlated with the solar wind dynamic pressure [5]. Several interpretations are under consideration:
- seasonal effect: the elevation of the Sun over the ring plane may modify the density of free electrons on top of the rings. This interpretation qualitatively fits to the variation of the observed period, but there is no explanation for the link between the 2 phenomena.
- solar cycle effect: the properties of the interplanetary medium and the solar wind are varying depending on the solar activity. It has been shown that the auroral radio emissions of Saturn are strongly correlated to the solar wind parameters.
- beating effect [6]: non random fluctuations of the longitudinal location of the radio active region. Simulations showed that it is easy to obtain apparent radio periods shifted from the sidereal period with such fluctuations.
- convection system in the core of Saturn: theory inspired by the Sun interior dynamics, but very unlikely to be applicable to Saturn.
None of these explanations really describe the observed variabilities, nor provide a way to derive the real sidereal period of Saturn.
The problem of the Saturnian sidereal period definition remains unsolved. It is particularly problematic for the atmospheric science at Saturn: if the measured radio period is actually 1% longer than the one measured at Voyager, all the atmosphere is super-rotating (i.e. rotating faster than the planet core), which is difficult to explane.

How long is a full day on Saturn? -- User:Atomic Religione
In reading about the hexagonal storm at Saturn's north pole today, both here and in the paper, it occured to me that this article is begging the obvious question of explaining why the storm is hexagonal. I think it would greatly improve that part of the article if a brief explanation of plausible reasons why scientists think the storm is shaped that way. The linked abstracts used for references aren't freely accessible so I can't tell if they talk about that subject in detail and could be used for further citation. Or, if there are as yet no good explanations for the storm, then the article should mention that fact.
So either present some possible explanations, or present references indicating that scientists are really stumped on the explanation. Dugwiki 21:09, 28 March 2007 (UTC)
To follow up, Mac Aavis posted an article describing a very likely sounding explanation for the hexagonal structure. A May 19 2006 Nature article describes a simple experiment that demonstrates how rapidly spinning fluid in a cylindrical bucket forms various polygonal shapes as the water recedes from the center. The shapes change according to the speed of the rotation, with a hexagonal shape at the center appearing at the highest settings the experimenters tested. While this might not be the underlying physical mechanism that's shaping the eye of the storm on Saturn, it seems like a very plausible one. Dugwiki 22:36, 28 March 2007 (UTC)
An excellent, comprehension article on the subject. For further development and possible
FA, I would suggest: 1) Make the prose "brilliant." 2) Add a bibliography or further reading, in addition to the inline citations. 3) Give an even amount of citations for each section; for FA, almost every paragraph or uncertain place needs a citation.

im just curious. it says the rings have places with different densities (some are questionable moons), this is no doubt due to the particles gravitational force acting on each other, so does this mean that in the distante future (millions of years) the rings gravitational force could eventually cause parts of the rings to 'clump' together to form a moon, or several moons? obvuasly disipating the rings so they are no longer there. For instance there is already gaps containing little moonlets like Pan is ther any evidance to support that this moon was formed by the particles in the rings gravitating together, and if so it would mean that over time the moon would expand, disipating the rings further. And as it says in the article some parts of the rings are slightly effected by the gravitational force of other moons. Could this be forming much like the creation of our solar system, as the rings gravitate into several moons, each at different distances away from saturn......so does this theory stand? and if so is it worth mentioning this possibility in the article? —The preceding unsigned comment was added by Special:Contributions/phill ( talk) 14:44, 3 April 2007 (UTC).
maby.... but the rings are actually (in some places) being held in place by the moons. And, opposite to what you said, moonlets like pan and
Enceladus are feeding the rings, parts of them are breaking off, or being blasted into the rings by impacts from comets, volcanic eruptions etc... rather than forming together from particles in the rings. in fact, the rings could increase in size, and the moons be depleted.--

The data in the infobox relating to the atmosphere (surface temperature, pressure, atmospheric composition) are currently unreferenced and vague. For example, what depth are we talking about here anyway? this NASA fact sheet appears to have good data, and, best of all, similar data are probably consistently given in the related data sheets for the other giant planets.

I recently removed imperial units from the infobox and various places in the Saturn article because this is a scientific article and imperial units are not used or recommended. Deuar reverted my edit and I wish to contest that.
Having miles in the infobox is cluttering and useless. Astronomical Units (AU) are useful and provide a sense of scale as well as being used by astronomers. The mile values are so big as to provide no sense of scale apart from "big". And if someone needed an exact figure they would use the km value in any calculations. Under MOSNUM Scientific articles are recommended to be SI. I propose these values are useless and cluttering and that they be removed.

After blundering around in the MediaWiki software development pages, I found the list of current bugs and feature requests (inside another system called Bugzilla). It turns out that "bug" (really request) number 235 for MediaWiki is for "auto conversion of units". The comments there have a discussion of possible markup syntax and challenges to implementing such a feature in the parser (precision, etc.). One of the comments notes that some version of "auto magic" unit conversion should someday be available as part of the "Semantic MediaWiki" extension to MediaWiki. Some related syntax is discussed in the SMW documentation, but it isn't clear to me whether it is currently implemented or only under consideration. A version of SMW was released in December, but apparently does NOT include this feature. And I don't know if/where SMW is deployed currently. But definitely something to watch.

In recent images from the Cassini spacecraft, Saturn's northern hemisphere appears a bright blue, similar to Uranus, as can be seen in the image below. This blue color cannot currently be observed from Earth, because Saturn's rings are currently blocking its northern hemisphere. The color is most likely caused by Rayleigh scattering.
From what I've learnt I thought Saturn looks blue not gold, perhaps the rings distort when spacecraft take images to make the planet appear yellow to orange colours. The sky is like blue-purple so what's a Rayliegh scattering?-- Freewayguy What's up? 00:02, 22 August 2008 (UTC)

A DAY on Saturn is pretty short, and it just got shorter.
The time it takes the ringed behemoth to complete a spin on its axis has just been calculated by astrophysicists at 10 hours, 34 minutes and 13 seconds, more than five minutes shorter than previous estimates.
A planet comprising clouds of gas driven by layers of mighty jetstreams, Saturn has no lasting visual landmarks as a rocky planet does, and this lack makes it hard to measure the planet's rotation.
As a result, astronomers have traditionally based their calculations on Saturn's magnetic field. But this signal can fluctuate and does not accurately measure how fast the planet's deep interior is rotating.
An international team led by scientists from Oxford University and the University of Louisville, Kentucky, used a different technique based on infrared images taken by the US spacecraft Cassini orbiting Saturn.
Their paper is released today by Nature, the British-based science journal.
"We realised that we could combine information on what was visible on the surface of Saturn with Cassini's infrared data about the planet's deep interior and build a three-dimensional map of Saturn's winds," said Oxford professor Peter Read.
"With this map, we were able to track how large waves and eddies develop in the atmosphere and from this come up with a new estimate for the underlying rotation of the planet."
Prof Read said that a "day" which had shortened by five minutes was a bigger deal than one might think.
"It implies that some of our previous estimates of wind speeds may be out by more than 160 miles (250 kilometres) per hour," he said.
"It also means that the weather patterns on Saturn are much more like those we observe on Jupiter, suggesting that, despite their differences, these two giant planets have more in common than previously thought." —Preceding unsigned comment added by 219.90.144.198 ( talk) 18:19, 29 July 2009 (UTC)

It is not clear from the article exactly what the link with the god Saturn is.
The text says "The Greeks had made the outermost planet sacred to Kronos, and the Romans followed suit." Does this mean they believed the object in the sky *was* the god? Or simply that it was some kind of object to associate with the god? And has the name been used for the planet ever since the god was first referred to, or was it a later association?

The degree to which a planet is "flattened" is inversely proportionate to the square of its rotational period and linearly proportionate to its radius. Due to its large radius and short orbital [rotational] period (10.57 hours - 44% that of Earth), it is has the highest degree of flattening of any of the planets in the solar system. —Preceding

I think this article several images that are of a similar nature. For example, you have three images of the hexagonal polar cloud feature, two of which are animated and are therefore large downloads. There's also a gallery of images at the bottom (including an animation), which could just as easily be located on the Commons. (In fact there is already a Saturn gallery on the Commons.)

Thanks. -- Mangst ( talk) 23:12, 10 October 2010 (UTC) Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Saturn is named after the Roman god Saturn, equated to the Greek Cronus (the Titan father of Zeus), the Babylonian Ninurta and the Hindu Shani. Saturn's astronomical symbol (♄) represents the Roman god's sickle.
Saturn, along with Jupiter, Uranus and Neptune, is classified as a gas giant. Together, these four planets are sometimes referred to as the Jovian, meaning "Jupiter-like", planets. Saturn has an average radius about 9 times larger than the Earth's. While only 1/8 the average density of Earth, due to its larger volume, Saturn's mass is just over 95 times greater than Earth's.
Because of Saturn's large mass and resulting gravitation, the conditions produced on Saturn are extreme if compared to Earth. The interior of Saturn is probably composed of a core of iron, nickel, silicon and oxygen compounds, surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium and finally, an outer gaseous layer.Electrical current within the metallic-hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is slightly weaker than Earth's magnetic field and approximately one-twentieth the strength of the field around Jupiter. The outer atmosphere is generally bland in appearance, although long-lived features can appear. Wind speeds on Saturn can reach 1,800 km/h, significantly faster than those on Jupiter.
Saturn has nine rings, consisting mostly of ice particles with a smaller amount of rocky debris and dust. Sixty-two known moons orbit the planet; fifty-three are officially named. This is not counting hundreds of "moonlets" within the rings. Titan, Saturn's largest and the Solar System's second largest moon (after Jupiter's Ganymede), is larger than the planet Mercury and is the only moon in the Solar System to possess a significant atmosphere —Preceding unsigned comment added by 86.134.8.226 ( talk) 10:53, 8 May 2011 (UTC)

The article says: Though there is no direct information about Saturn's internal structure, it is thought that by whom? its interior is similar to that of Jupiter. I think it is too difficult for the readers to determine the probability that this speculation is true. It hints at indirect information. Is this only that Saturn is similar to Jupiter? How probable is that? Who thinks that? I am not able to follow the link. How do we know about Jupiter's interior? I have avague memory of a satellite probe. Is that it? See also WP:WEASEL.

Interior structure is not only about structure, but also about temperature and the processes that presumably generate heat. It seems that the article mostly assumes that the atmosphere is not part of the interior. But there is information about the atmosphere in Interior structure. This distinction is also obscure because the transition between gas and liquid is assumed to be gradual. -- Ettrig ( talk) 17:15, 3 December 2011 (UTC)

I'm not sure the following should have a place in this article:
The citation is to a rather speculative article of dubious quality. The estimate hinges, for example, on assuming a particular conversion for a traditional unit. The hypothesis favored by the cited source is that "at some time in the past, ancient astronomers possessed realistic values for the diameters of the planets." The alternative explanations provided in the source are, in essence, that it is coincidence or fraud. The source then argues against each of these "alternative explanations."
Unless we think our article should present the largely unsupported concept of ancient advanced knowledge of planetary diameters, I propose this sentence be deleted. If there are no counterarguments within the next week, I shall make the deletion.

Why are speeds given in km/hr rather than ms-1? Firstly, this is a scientific article and the Wikipedia standard recommends SI units, that is (again according to Wikipedia) MKS units. More importantly, I feel, units such as mph, km/h, knots etc. are only really relevant to terrestrial transport. In this example of wind speed on Saturn (which I would guess from the value that the author converted from 500m/s), I and, I suspect, most people reading the article, can readily visualise a distance of 500m and an object blowing past. A second later it's gone that far! Whereas, "Imagine driving along at 1,800km/h and sticking your hand out of the window." somehow doesn't give the same feel.
Also, why not state very large distances in scientific notation? When coming to a subject like this for the first time I usually want one, or two at the most, digits of precision and an order of magnitude. Having to count digits and commas makes it more difficult to take in the information at a glance, although I admit that in this case AUs give me at least a far better feel for the scale.
Sorry, I've just read the cloud layers section, where m/s are used. However, I still think this gives a better feel for speed than km/h even in an introduction. — Preceding unsigned comment added by Chrisbaarry ( talk • contribs) 01:15, 20 May 2012 (UTC)

Surprisingly, the article mentions absolutely nothing regarding the rotation of Saturn's rings. There is no content in regards to how fast the rings rotate around the planet. Or if there is a difference in speed between the rotation of the planet itself in comparison to the speed of the rotation of the rings. In fact, the reader can't even properly deduce whether the rings even rotate at all, or whether they remain stationary around the planet as the sphere rotates within it.

My 2¢: It's easy to ref 62 known moons w RS's. The article on the A-Ring "features" that interprets them as moonlets says that "a third of [the 150 features] are demonstrated to be persistent by their appearance in multiple images". In all other articles, we only count moons when their orbits have been well determined and they've been given formal designations. It's not clear how many of the third of the 150 qualify under that standard; only one has received an informal name, and AFAICT none have received formal designations. IMO, we should state that there are 62 moons with formal designations, and in addition innumerable undesignated moonlets within the rings. — kwami ( talk) 22:40, 24 July 2013 (UTC)

I am going to delete the current figure (reproduced here for convenience), which seems to me to be rather uninformative. In particular, it lacks any useful explanation in the caption. I think the body with the heavy red line must be Jupiter, and the outer body Saturn, which seems to agree if the radial divisions are in AU. But then there is a strange body closer in, that seems to be at about 3.5 AU (? Ceres?) and one that may be the Earth closer still in that is difficult to make out. Anyhow, if someone can show that the figure has any pedagogic value and conveys something useful, please explain it and (maybe) restore it. A diagram from above (ecliptic pole, or from the normal to the fundamental plane of the Solar System -- defined by its total angular momentum) with the orbits of the six inner planets, might be somewhat informative, showing the relative distances and non-circularity of the orbits of Mercury and Mars, but not too relevant to Saturn. It is hard to get in Uranus, Neptune, and Pluto on a linear scale without much crowding of the inner planets, I think. Wwheaton ( talk) 22:11, 25 March 2015 (UTC)
this is the data you can find in this page
planet radius at equator: 60268000 meters
winds max speed: 500 m/s
planet rotation at equator: ~10h
you can calculate the planet's circumference at equator (radius*2*pi) = 378675012 m
and the time the winds will take to make a full turn = 378675012 / 500 = 757350 seconds per turn
which is 210 hours.
Is there a problem with the data or am I just doing the calculations wrong?
Lessio ( talk) 10:28, 7 April 2015 (UTC)
quoting what's written in the page:
System I has a period of 10 h 14 min 00 s (844.3°/d) and encompasses the Equatorial Zone, the South Equatorial Belt and the North Equatorial Belt.
All other Saturnian latitudes, excluding the north and south polar regions, are indicated as System II and have been assigned a rotation period of 10 h 38 min 25.4 s (810.76°/d).
The polar regions are considered to have rotation rates similar to System I.
System III refers to Saturn's internal rotation rate. Based on radio emissions from the planet in the period of the Voyager flybys, it has been assigned a rotation period of 10 h 39 min 22.4 s (810.8°/d).
I thought system I and II were talking about the atmosphere rotation and system III about the core
Lessio ( talk) 11:26, 7 April 2015 (UTC)
I had time to check and it turns out wind speed is calculated relative to the planet rotation.
so the 210 hours per rotation are the time clouds take to go around the planet and return over the same spot of the planet. and since the planet rotates every 10 hours the clouds rotate a bit faster than that.
Problem solved, If someone wants to add this to the main page I think it will avoid future doubts.

Page 148 reads: "Without the value of Saturn's daily rotation, winds cannot be understood with certainty. But scientists are beginning to discern a pattern of winds throughout the outer Solar System. Winds are better understood for Jupiter, Uranus and Neptune, as each planet has an offset magnetosphere. Saturn's wind speeds are understood in a relative sense. [...] Currently, winds on saturn are still documented using the voyager data for saturn's lenght of day. [...] If analysts change their estimates of the lenght of saturn's rotation by just 3 min, the zero wind speed lines move up or down the scale by 40m/s.

I just did a bit of revising to the Observation section. It was a jumbled mess, confused "occultation" with "opposition", had sentences out of order, and treated some recent ephemeral data as if it were noteworthy, when in actuality it describes fairly common behaviour of Saturn. I removed the ephemeral stuff and rearranged/corrected the rest so that it made sense. People who don't know much about practical astronomy really ought to stay away from editing "observation" sections. — Preceding unsigned comment added by LoveCowboy2024 ( talk • contribs) 6 June 2014
I don't want to add this as it may be seen as superfluous, but surely the line 'Saturn is the most distant of the five planets easily visible to the naked eye, the other four being Mercury, Venus, Mars and Jupiter.' should actually say six planets, Earth is visible to the naked eye too. The line should either say 'visible from Earth', or include Earth in the list of those that are visible. 94.8.24.204 ( talk) 09:04, 9 October 2015 (UTC) Done Isambard Kingdom ( talk) 09:30, 9 October 2015 (UTC)

Section 6: Natural satellites states "Saturn has at least 150 moons and moonlets, 53 of which have formal names." This is at variance with the main article, Moons of Saturn, which states " Saturn has 62 moons with confirmed orbits, 53 of which have names...", and with the NASA page http://solarsystem.nasa.gov/planets/saturn, which states 62 moons, 9 awaiting confirmation.
One of the references for the 150 moons statement is a paper titled "The population of propellers in Saturn's A Ring". The abstract says "We present an extensive data set of ~150 localized features from Cassini images of Saturn's Ring A, a third of which are demonstrated to be persistent by their appearance in multiple images [...] We interpret these features as the signatures of small moonlets embedded within the ring..."
The author of the 'Natural satellites' section has apparently confused the "~150 localized features" statement in that paper, with confirmed moons; the paper itself says that only a third of those features are persistent.
I would suggest for internal consistency, matching the Moons of Saturn article.

In the section "Planetary Rings" The following paragraph should be significantly altered or removed entirely:
In the past, astronomers once thought the rings formed alongside the planet when it formed billions of years ago.[80] Instead, the age of these planetary rings is probably some hundreds of millions of years.[81]
Source [81] links to an official-looking, but entirely nonacademic article hosted on a creationist website ( http://creationconcepts.org/) using the hypothesis of the early age of the rings to support creationism. Clearly this has no place in a scientific article.
Note, however, that there does exist uncertainty on the age of the ring system. Here is an academic article the supports a young age: http://arxiv.org/abs/1603.07071, and here is one discussing the old age: http://www.nasa.gov/mission_pages/cassini/media/cassini20071212.html. I don't know which interpretation is most popular/accepted in the scientific community. — Preceding unsigned comment added by 96.90.214.117 ( talk) 14:10 12 June 2016 (UTC))
I wanted to look up future seasons on Saturn just now, in order to figure out when you can send a spacecraft to photograph an illuminated South pole of Enceladus - so in the Saturn's summer approximately.
I got these figures here, where someone has just calculated them and posted the figures to a forum, surprised that it's not in wikipedia and not found it anywhere else just searching now: http://www.cloudynights.com/topic/360680-solsticeequinox-dates-for-saturn/
"2009 AUG 10 – Vernal Equinox
2013 MAY 16 – Spring Cross-Quarter
2017 MAY 24 – Summer Solstice
2021 JUN 20 – Summer Cross-Quarter
2025 MAY 05 – Autumnal Equinox
2028 DEC 02 – Autumn Cross-Quarter
2032 APR 11 – Winter Solstice
2035 AUG 04 – Winter Cross-Quarter
2039 JAN 22 – Vernal Equinox"
I think the article should have a section on Seasons on Saturn - unless I'm missing it somehow? What do you think? Robert Walker ( talk) 21:34, 25 June 2016 (UTC)

Please change
pressure range 3–6 bar with temperatures of 290–235 K
to
pressure range 3–6 bar with temperatures of 190–235 K
This looks like an obvious mistake. The thick part of the atmosphere gets warmer with increased pressure.
Thanks!

I have an issue with the following paragraph:
On 8 January 2015, NASA reported that a team of scientists from the Jet Propulsion Laboratory determined the barycenter of the planet Saturn and its family of moons to within 4 km (2.5 mi) using data from an experiment conducted with the Cassini spacecraft and the Very Large Base Array.
Why do I have an issue with the preceding paragraph? Simple, it provides no information!
It's an announcement of a discovery without revealing what was discovered. It even provides the uncertainty of the value, but not the value. It's a tease. OzMaz ( talk) 19:35, 12 October 2017 (UTC)

Hello, I would love to edit this page directly but it is locked. In the rings section a 2002 paper is cited indicating Saturn's rings are 93% water. On the wiki page dedicated to the rings [17], a 2008 paper is cited that uses Cassini data to peg the ring composition at 99.9% water. Please update the Saturn page to reflect the newer data. Thanks!

In sidebar, synodic period shows same popup as orbital period. — Preceding unsigned comment added by 109.133.13.222 ( talk) 15:08, 25 July 2018 (UTC)
The new values of brightest and faintest apparent magnitude in the ‘infobox’ were reported in a peer-reviewed journal article that includes updated equations for computing planetary magnitudes. Those formulas will be used to predict magnitudes for future issues of The Astronomical Almanac published by the U.S. Naval Observatory and Her Majesty’s Nautical Almanac Office. The equations were solved at daily intervals over long periods of time in order to determine the magnitude extremes. As noted in the journal article, the apparent brightness of Saturn depends very strongly on the inclination of its rings system. The extreme magnitudes reported here take that angle into account. The paper in Astronomy and Computing can be located at https://doi.org/10.1016/j.ascom.2018.08.002. — Preceding unsigned comment added by Planet photometry ( talk • contribs) 14:38, 13 September 2018 (UTC)
This article is awful. There are too many things wrong with it to describe here. The discussion of the planet's oblateness implies that only the gas giants are oblate. The box gives a single value for rotation rate when 1) it doesn't have a surface and 2) the rotation varies over a continuum of rates. The article talks about gravity without explanation of why the core (which IS solid) doesn't have a surface or if it does (I have no idea what the transition region between liquid and solid is like, whether it is a more or less discrete phase boundary or whether the transition is more gradual (or chaotic))) why that boundary isn't considered to be "the" planet's surface. Worse, it mentions the "gravity" at the equator is if that has its normal Earth surface meaning (i.e. approximately constant) rather than at a distance (arbitrarily at the theoretical distance where atmospheric pressure is guessed to average 1 atm.) from the barycenter determined by crude modeling. And it gives a value for the gravitational acceleration as if it is a constant (like Earth's). The section on the atmosphere claims its composition is similar to the primordial solar system's and goes on to state:"The total mass of these heavier elements [the astronomical metals] is estimated to be 19–31 times the mass of the Earth, with a significant fraction located in Saturn's core region." What has this to do with its Atmosphere??? I could go on and on. Needs a rewrite. 72.16.99.93 ( talk) 09:06, 19 January 2019 (UTC)
