Uranus
From NSwiki, the NationStates encyclopedia.
Uranus, the seventh planet from the Sun, is likely among the least heavily inhabited planets in the Solar System. Because of its nature as a gas giant and its very high gravity, the actual surface of Uranus is uninhabitable. However, a number of powers have established bases on Uranus's moons and on space stations orbiting the planet. These include Taurenor, Autonomous City-States, Reploid Reproductions, and Ventuus.
