The planet, which exceeds the mass of the Earth by only 14 times, is the lightest of the entire outer group. Uranus is 4 times larger than Earth.
The discovery of the ten rings of Uranus was an astronomical sensation. They are very thin, consist of stone particles and have a very low reflectivity. The plane of the rings almost coincides with the plane of the equator.
Uranus is unique in that it rotates “on its side”, since the tilt of its axis of rotation is about 98 degrees.
This planet has a very cold core, radiating large amounts of heat into space.
There are 27 known satellites of Uranus, including Ariel, Miranda, Oberon, Titania and others.
