Uranus

Uranus is one of the gas giants, the third largest planet (after Jupiter and Saturn) and the fourth heaviest one. Uranus was identified as a planet in the 18th century.

Uranus consists mostly of gas and various ices, with about 85% hydrogen, 15% helium and vestiges of methane. This separates him from the other gas planets Jupiter and Saturn.

Uranus has an axial tilt of 90°, so that the each of the two poles are facing the Sun on one point of the orbit around the sun. The reason for this extreme tilt is not known.

There are very light rings around Uranus. 27 moons are orbiting him.

His name comes from the Greek god of the sky which was the ancestor of the other Greek gods.
