My understanding is that Earth itself is only in the CHZ due to its Greenhouse gases (although this may well be mistaken, and/or depend on who is defining the CHZ, etc). I think I read that explicitly stated (without my qualifiers about who is defining CHZ, etc) many years ago somewhere in
Carl Sagan's book Broca's Brain. Arguably this is implicit in our article, but it does not seem to be clearly or explicitly stated with the backing of Reliable Sources. I think our article would be improved if this were done (with suitably-worded qualifiers if needed), and I may (or may not, per
WP:NOTCOMPULSORY and
WP:BNO) eventually try to do so myself, tho I suspect it will be done (if it ever does get done) quicker and better by more interested and competent editors than me.

Is one coming, a large one?
Has one been recently?
I am thinking about the one in Arizona, 60+ years ago?

@
LaundryPizza03: The term "habitable zone" has multiple meanings outside of circumstellar habitable zone and galactic habitable zone though. That's why I chose the term "Goldilocks zone" over "habitable zone" despite google ngram showing that the latter is more common because ngram counts all definitions of habitable zone so there is no way to know its actual frequency when referring to this topic and how it compares to the frequency of "Goldilocks zone". –

Oppose, the term "Goldilocks zone" is only used by popular sources; the term used by astronomers is "habitable zone". Would support a move to the latter title per above, it already redirects here and is unlikely to be ambiguous as this is by far the most common use of the term.

In an article about science we should use scientific terms. In any case I'm pretty sure "habitable zone" is the more common term in popular sources too.

CHZ extreme conservative limits
The Earth has an orbit eccentric enough to take it outside these limits more often than not. The extreme conservative limits are 0.99-1.004 AU, while the Earth's orbit varies from ~0.98-1.02 AU.
