Stephano (S/1999 U2), the 20th satellite of Uranus, is named after the ship's butler in Shakespeare's play The Tempest. Very little is known about Setebos. A small moon, it as an estimated 10 kilometres in diameter.

Orbit

Stephano orbits Uranus at an average distance of 0.8 million kilometres in an elliptical and highly inclined retrograde orbit - opposite to that of Uranus itself and the planet's larger moons. It is very likely a captured asteroid.
