Lakes and rivers of Titan

Hydrocarbon lakes on Titan, a moon of Saturn

Lakes of liquid ethane and methane exist on the surface of Titan, Saturn's largest moon. This was confirmed by the Cassini–Huygens space probe, and had been suspected long before. The large bodies of liquid are known as maria (seas) and the small ones as lacūs (lakes).
