This planet has an unusual blue-green colour. This colour comes from methane which is present in abundance in hydrogen–helium atmosphere of the planet.
Rings of Uranus are narrow and are only a few km wide. Some astronomers opine that these rings are young are possibly relatively recent. The planet has 13 rings.

It is the only planet that spins on its side (like a barrel)! Scientists think that this is due to a collision millions of years ago.
