Uranus is named after the Greek god of the sky. Uranus is a gas giant with five moons. Uranus is the third largest in the solar system by diameter, and the fourth largest by mass. It was discovered in 1690 and originally named as 34 Tauri.
Uranus is mostly made up of ice and various gasses. The atmosphere is 83 percent Hydrogen, 15 percent Helium, 2 percent Methane, and traces of Acetylene. The surface temperature is -360 °F. Uranus has a faint planetary ring consisting of dark particulates up to 10 meters in diameter and was discovered on March 10, 1977. In December 2005, the Hubble Space Telescope discovered a pair of previously unknown rings. NASA’s Voyager 2 spacecraft is the only one to have visited the planet; no other missions are currently planned.
