Titan is Saturn's largest moon and the second-largest in the Solar System. It is the only moon with a dense atmosphere, thicker than Earth's, and the only other world known to have stable liquid on its surface, in the form of lakes and seas of methane and ethane. A probe, Huygens, landed there in 2005.
