Uranus Uranus has a diameter of 31,600 miles and is 1,780,000,000 miles from the sun. It has 11 thin, faint rings and 15 moons. The most notable moons of Uranus are both Oberon and Titania. The planet rotates in about 17 hours and revolves around the Sun every 84 Earth years. Uranus spins vertically rather than horizontally.
Some scientists think it collided with another planet long ago and was knocked over.
As the planet orbits , first one pole, then the equator, then the other pole, then the equator again, face the sun. Uranus is very cold. This is cold enough to freeze-dry human flesh instantly. Gravity on Uranus is about the same as that of Earth. Like Jupiter, Saturn, and Neptune, Uranus is a gas giant.
