The mean temperature on the surface of Uranus' cloud layer is -350°F (59K).
The planet is shrouded in an icy cloud layer (made up of frozen methane, ethane, and acetylene) circling this planet at 185 mph (300 kph. Uranus' icy atmosphere consist of 83% hydrogen,15% helium, and 2% methane. The outer layers of the atmosphere are the coldest; temperature and pressure rise under the cloud layer.
Uranus is about 31,690 miles (51,118 km) in diameter.
