Titan (Sol 6a) is a moon of Saturn (Sol VI), United Empire of Earth (UEE). The largest of Saturn's moons, its nitrogen-methane atmosphere is denser than that of Earth (Sol III). Titan is dotted with lakes and rivers of liquid hydrocarbons, and its climate has created surface features such as dunes, seas, and canyons, all shaped by a methane cycle rather than a water cycle.
