3rd of the 4 gas giants. Uranus has a rocky core wrapped in a mantle of gases and ice. Surrounding the mantle is an atmosphere containing methane, which gives Uranus it's distinctive blue-green color. Cloud tops have a temperature of -210 C (-346 F). Uranus has 15 moons and a ring system. Uranus has almost no visable features. Only 1 feature has been observed by the space probe Voyager 2 in 1986, and that was a few methane clouds.
