Uranus is the seventh planet from the Sun. Uranus has been revealed as a dynamic world with some of the brightest clouds in the outer solar system and 11 rings. Uranus is so distant that it takes 84 years to complete one orbit. The atmosphere of Uranus is composed primarily of hydrogen and helium, with a small amount of methane and traces of water and ammonia. Uranus gets its blue-green color from methane gas.
