The atmosphere of Uranus is made up of hydrogen, helium and methane that is probably wrapped around a core of rock and ice. The methane absorbs red light making Uranus appear blue green.

Uranus narrow has rings, though not as thick as those of Saturn. There are 27 moons orbiting this planet, the two largest of which are Oberon and Titania.

Uranus is the coldest planet in the Solar System, and takes 84 Earth years to orbit the sun. This means that each of its poles has 42 years of continuous daylight and then 42 years of continuous night.

The Voyager 2 space probe visited Uranus on January 24, 1986.

Uranus was discovered in 1781 and is named after the Greek god of the sky.
