About Uranus
Uranus is the seventh planet from the Sun, an ice giant with a pale blue-green colour that comes from methane in its atmosphere. It is the coldest planet, with cloud-top temperatures near −220 °C.
Uranus is tipped almost completely on its side, so it appears to roll along its orbit. This extreme tilt gives it decades-long seasons, with each pole spending about 42 years in continuous sunlight and then darkness.
- Rotates on its side (~98° tilt)
- The coldest planet in the solar system
- First planet discovered with a telescope
