Uranus

Uranus is the seventh planet from the Sun. It is a gaseous cyan-coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, which astronomers call "ice" or "volatiles". The planet's atmosphere has a complex layered cloud structure, and has the lowest minimum temperature of all of the Solar System's planets. It has a marked axial tilt of 82.23°, with a retrograde rotation period of 17 hours and 14 minutes. This means that in an 84-Earth-year orbital period around the Sun, its poles get around 42 years of continuous sunlight, followed by 42 years of continuous darkness.
