Trinculo was discovered on Aug. 13, 2001 by Matthew Holman, John J. Kavelaars and Dan Milisavljevic at the Dominion Astrophysical Observatory in Victoria, British Columbia, and by using the 4-m reflector at the Cerro Tololo Inter-American Observatory in Chile.


About 11 miles (18 kilometers) in diameter (assuming an albedo of 0.04), Trinculo is a small, dark moon orbiting Uranus in the opposite direction from the regular moons and the planet's rotation (called a retrograde orbit).

How Trinculo Got its Name

Originally called S/2001 U1, Trinculo was named for the jester in Shakespeare's play "The Tempest."
