Uranus

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.

Uranus (mythology)

In Greek mythology, Uranus, sometimes written Ouranos, is the personification of the sky and one of the Greek primordial deities. According to Hesiod, Uranus was the son and husband of Gaia (Earth), with whom he fathered the first generation of Titans. However, no cult addressed directly to Uranus survived into classical times, and Uranus does not appear among the usual themes of Greek painted pottery. Elemental Earth, Sky, and Styx might be joined, however, in solemn invocation in Homeric epic. The translation of his name in Latin is Caelus.
