The only known moon in the Solar System with an atmosphere, Titan has rain, storms, lakes, oceans, valleys, mountain ridges, mesas and dunes. .

“The depth and composition of each of Titan's seas had already been measured, except for Titan’'s largest sea, Kraken Mare, which not only has a great name, but also contains about 80% of the moon's surface liquids,” said lead author Valerio Poggiali, research associate at the Cornell Center for Astrophysics and Planetary Science (CCAPS).
