Uranus Facts
Uranus was discovered in 1781 by William Herschel, and it is the seventh planet away from the sun. Uranus and Neptune are similar in the composition and are sometimes called ‘ice giants' by astronomers. Uranus is the only planet named from a Greek mythological figure, while the others are all named from Roman mythological figures. Uranus has a ring system surrounding it, and it also has many moons. It is possible to see Uranus with the naked eye but originally astronomers did not classify it as a planet due its slow orbit and its dim appearance.
