Trinculo /ˈtrɪŋkjʊloʊ/ is a retrograde irregular satellite of Uranus. It was discovered by a group of astronomers led by Holman, et al. on 13 August 2001, and given the temporary designation S/2001 U 1.[1]
Confirmed as Uranus XXI, it was named after the drunken jester Trinculo in William Shakespeare's play The Tempest . Trinculo is the second smallest of Uranus' 28 moons after Ferdinand and is approximately only 18 km wide.
