Saturn’s largest moon Titan experiences clouds, rain, rivers and changing seasons like Earth

Titan has four seasons like Earth, but each lasts about 7.5 Earth years because Saturn takes 29 years to orbit the Sun.

Titan is the only moon with a thick atmosphere and the only world besides Earth with liquid flowing on its surface.

The Cassini spacecraft flew past Titan over 100 times between 2004 and 2017, observing less than half of a Titan year.

Titan's surface is so cold that liquid methane forms clouds, rain, rivers, and lakes instead of water.

Scientists study Titan's seasonal changes using Cassini data, including variable wind directions and shifting sand dunes.
