Titan
[<] - [1] - [2] - [3] - [4] - [5] - [6] - [7] - [>]A Closer Look at the Atmosphere
Voyager and Cassini have obtained close looks at Titan's thick atmosphere.It consists mostly of nitrogen, as does Earth's, but It also contains a substantial percentage of "smog-like" chemicals such as methane and ethane. Earth's primordial atmosphere was made up of similar compounds.
The surface temperature on Titan is around -180° C. Liquid hydrocarbons could exist there. Liquid methane could rain onto and flow across the surface.
