Oberon

From Slackerpedia Galactica

Oberon is the meddlesome King of the Faeries in Shakespeare's A Midsummer Night's Dream, and is also a largish-but-otherwise-inoffensive moon of the planet Uranus. The names of all moons of Uranus come from either Midsummer... or from the works of Alexander Pope (a smallish-and-occasionally-offensive English writer of the 18th Century). Oberon -- the moon, not the Shakespeare character -- was discovered in 1787 by William Herschel, who discovered Uranus itself six years earlier.

As with many objects in the outer solar system, it is composed of a mixture of icy and rocky materials, with the largest fraction by mass being volatile compounds like water and methane ices. The small number of pictures taken by Voyager 2 during its 1986 flyby of Uranus revealed Oberon to have an old, heavily cratered surface, meaning little or no resurfacing has occurred since its formation. It is likely to be geologically dormant.
