Uranus Data

Uranus - the Magician from the Planet Suite - Holst

Click to listen!

Uranus, the third of the gas giants, was discovered in 1781 by William Herschel. He was not looking for a planet, but, "reviewing the heavens". He identified it as not being a star because it showed a small disk. Uranus is just visable with the naked eye, and it had been seen on several occasions before Herschel's discovery. John Flamsteed, England's first astronomer Royal, even included it in his star catalogue and gave it a number: 34 Tauri!
