Titan is the only known celestial body other than earth to have stable pools of a liquid element on its surface. As Earth has a hydrological atmosphere (water makes clouds, pools etc.) Titan has an atmospheric cycle of methane.

Answer 2

Titan is interesting due to its dense atmosphere, composed mostly of nitrogen and methane, creating a unique environment different from Earth. It also has liquid methane and ethane lakes on its surface, making it the only known celestial body to have stable bodies of liquid besides Earth. Additionally, Titan has a thick orange haze that obscures its surface, adding to its mysterious and intriguing nature.
