Sorry. This is Uranus, the solar system's third largest
planet in diameter. It was discovered in 1781 by William
Herschel, but has only been visited by one spacecraft,
Voyager 2. Uranus is made up of mostly rock and ice. Its
interesting blue color comes from the methane found in its
atmosphere, which absorbs red light.
