How does Uranus compare to other planets?
Uranus, almost four times the diameter of Earth, is the third largest in our solar system after Jupiter and Saturn, but is slightly less dense and less massive than its near-twin Neptune. Uranus is unusual in that it rotates on its side - the axis about 97 degrees to the orbital plane. It is called an ice giant (or sometimes, gas giant) being mostly gas, unlike the inner or rocky planets like Mercury, Venus, Earth, and Mars.
