The seventh planet from the sun is much like its gaseous neighbors,
with a cloudy surface, rapid winds, and a small rocky core.
Perhaps because of a collision with a large object long ago, Uranus
orbits at an extreme tilt of 98 degrees - sort of on its side. This causes
one pole to point toward the sun for decades, giving the planet strange
Uranus has numerous satellites and a faint set of rings. If all the
possible satellites being studied are confirmed, Uranus would have 16
regular and five irregular moons, making it the most populated planetary
satellite system known. Saturn is known to have 18 satellites (there may
be more, but they have not been well-documented).
Uranus was thought to be a star until William Herschel discovered in
1781 that it orbited the Sun.
