Caliban and Sycorax are recently discovered moons of Uranus. Both were discovered by land-based telescopes in 1997. Caliban (formerly known as S/1997 U 1) orbits Uranus at about 4.5 million miles and has a diameter of only 50 miles. Sycorax (formerly known as S/1997 U 2) orbits Uranus at about 7.6 million miles and has a diameter of only 100 miles. Their sizes are estimated based on how bright they appear. The name Caliban comes from a character in Shakespeare's play The Tempest who is a savage, deformed slave of the magician Prospero. The name Sycorax comes from a witch in the same play. Caliban was discovered by using the 200 inch Hale telescope. Before these moons were discovered Uranus was thought to be the only one of the gas giants not to have moons that orbit in a plane other than that of the equator.
