Uranus

Uranus is the seventh planet from the Sun, and the third-largest and fourth most massive planet in the Solar System.  Uranus is similar in composition to Neptune, and both are of different chemical composition than the larger gas giants Jupiter and Saturn. As such, astronomers sometimes place them in a separate category, the “ice giants”.

Uranus’s atmosphere, while similar to Jupiter and Saturn’s in its primary composition of hydrogen and helium, contains more “ices” such as water, ammonia and methane, along with traces of hydrocarbons.

Like the other giant planets, Uranus has a ring system, a magnetosphere, and 27 known moons. The Uranian system has a unique configuration among the planets because its axis of rotation is tilted sideways, nearly into the plane of its revolution about the Sun. As such, its north and south poles lie where most other planets have their equators.  (From Wikipedia)
