Who discovered Uranus?

The planet Uranus was discovered by William Herschel on March 13, 1781. He discoverd Uranus while surveying stars in the night sky using a telescope that he had built himself. Herschel noticed that one of these "stars" seemed different, and after observing it many more times, noticed that it orbited the Sun. He calculated that Uranus had an orbit that was about 18 times farther from the Sun than Earth. Herschel also discovered two of the moons of Uranus (Titania and Oberon).
