Oberon

Oberon

[O'buh ron] is the second largest satellite of Uranus, with a diameter of 942 miles (1,517 kilometers). It orbits around Uranus at an average distance of 362,304 miles (583,420 kilometers). It was discovered by William Herschel in 1787, and named for the King of the Fairies and husband of Titania in Shakespeare's Midsummer-Night's Dream.

Like Uranus' other large moons, Oberon is a mixture of about 40-50% water ice with the rest rock. Its heavily cratered surface has probably been stable since its formation, but large faults across the southern hemisphere suggest some geologic activity early in its history.
