Detailed explanation-1: -Titan has clouds, rain, rivers, lakes and seas of liquid hydrocarbons like methane and ethane.

Detailed explanation-2: -Titan’s surface is sculpted by flowing methane and ethane, which carves river channels and fills great lakes with liquid natural gas. No other world in the solar system, aside from Earth, has that kind of liquid activity on its surface.

Detailed explanation-3: -We now know that Titan is a world with lakes and seas composed of liquid methane and ethane near its poles, with vast, arid regions of hydrocarbon-rich dunes girdling its equator. And deep below the surface, Titan harbors a large internal ocean.

Detailed explanation-4: -Saturn’s largest moon, Titan, is a true space oddity. It’s the only natural satellite in the solar system that has a thick, dense atmosphere, and it’s the only extraterrestrial object we know of to feature persistent lakes and seas-though ones filled with liquid methane and ethane rather than water.

Detailed explanation-5: -The weather on Titan is driven by a methane cycle similar to Earth’s water cycle – methane rains down from the sky and fills the lakes and seas near the poles. But we have never quite understood where all that methane comes from, since it should be chemically destroyed fairly quickly in the atmosphere.
