The seventh planet in order of distance from the Sun is Uranus.
Uranus lies beyond Saturn and before Neptune, at an average distance of about 2.9 billion kilometres from the Sun. It is an ice giant, meaning its interior contains large amounts of water, ammonia and methane-rich material rather than being composed mainly of hydrogen and helium like Jupiter and Saturn.
Methane in Uranus’s upper atmosphere absorbs red light, giving the planet its blue-green colour. Uranus is also famous for its extreme axial tilt of about 98 degrees, making it appear to rotate on its side. This produces unusually severe seasons, with each pole facing the Sun for roughly half of its 84-year orbit.
Uranus was discovered as a planet by William Herschel in 1781. It is sometimes confused with Neptune, but Neptune is the eighth planet and is farther from the Sun.
