Moon of Saturn
Erriapus , or Saturn XXVIII (28), is a
prograde
irregular satellite of
Saturn . It was discovered by
Brett Gladman ,
John J. Kavelaars and colleagues in 2000, and given the temporary designation S/2000 S 10 .
[7]
[8] It was named Erriapo in August 2003
[9] after Erriapus (also rendered Erriappus ), a giant in
Gaulish mythology ; the name was changed from
dative Erriapo to
nominative Erriapus per
IAU conventions in late 2007.
[10]
[11]
Erriapus is about 10 kilometres in diameter, and orbits Saturn at an average distance of 17.5 Gm in 871 days.
As a member of the
Gallic group of irregular satellites, which share similar orbital characteristics and a light-red colour, Erriapus is hypothesized to have its origin in the break-up of a common progenitor of the group,
[6]
[12] or to be a fragment of its largest member,
Albiorix .
[13] It has a rotation period of 28.15± 0.25 h , and is thought to rotate on its side, giving it similar seasons to those of
Uranus .
[14]
[15] With a fairly elongated shape, it is a candidate for a
contact binary or binary moon.
