All about Uranus and Neptune
Uranus and Neptune are known as ice giants because they contain a lot of water, ammonia and methane ice. They are far from the Sun and very cold. Uranus is tilted on its side, so its poles point almost at the Sun during parts of its orbit.
Neptune is the farthest planet from the Sun and has the fastest winds in the Solar System, reaching more than 2,000 kilometres per hour. Its deep blue colour comes from methane in its atmosphere, which absorbs red light.
