Uranus is the seventh planet from the Sun in our Solar System. This huge, icy planet is covered with clouds and is encircled by a belt of 11 rings and 18 moons. Uranus' blue color is caused by the methane in its atmosphere; the methane molecule absorbs red light.
Uranus' rotational axis is strongly tilted on its side (97.9°). Instead of rotating with its axis roughly perpendicular to the plane of its orbit (like all the other planets in our Solar System), Uranus rotates on its side (along its orbital path). This tipped rotational axis gives rise to extreme seasons on Uranus.
