Seasons of Uranus. The planet is tipped onto its side, so it orbits lying down. This means that each season is twenty years long. (Graphic credit: M.Showalter & M. Gordon, SETI institute) Mona Evans, "Uranus Facts for Kids" http://www.bellaonline.com/articles/art27632.asp
Uranus. Its blue-green color comes from methane crystals in the atmosphere. The rings do circle the equator, but Uranus is tipped so much on its axis that it orbits on its side. (Image credit: Voyager, NASA) Mona Evans, "Uranus Facts for Kids" http://www.bellaonline.com/articles/art27632.asp
Uranus is the third largest planet in our Solar System. Uranus has nine major rings and 27 known moons. This image, taken by the Hubble Space Telescope in infrared reveals cloud structures not normally visible. Methane gas in the upper atmosphere absorbs red light, giving the planet its blue-green color. Uranus is spinning on its side, probably because of a collision with a large object early in the Solar System's history.
