Setebos (moon)

Setebos /ˈsɛtɛbʌs/ is one of the outermost retrograde irregular satellites of Uranus.

It was discovered on 18 July 1999 by John J. Kavelaars et al. and provisionally designated S/1999 U 1.

[8] Confirmed as Uranus XIX, it is named after the god worshipped by Caliban and Sycorax in William Shakespeare's play The Tempest.

The satellite appears neutral (grey) in visible light (colour indices B−V = 0.77 , R−V = 0.35 ),[10] similar to Prospero but different from Sycorax (which is light red).

A crater on Umbriel is also named after Setebos, but with the spelling Setibos.
