Why was Uranus named what it was? Why was Uranus named what it was, and who came up with the name?
Herschel, the discoverer of the planet named it Georgium Sidus, "George's star" after his patron, King George III of Great Britain.

The name was not popular outside of Great Britain, and there were various other proposals. It was Johann Elert Bode who proposed Uranus, the Latin form of the Greek god of the sky.  It fits with the existing planets having the names of Roman Gods, and just as Saturn was the father of Zeus, so Uranus was the father of Saturn.
