Titan, the cloudy moon of Saturn, is one of the least hostile places (for humans) in the outer solar system. It has lakes of liquid methane, and even weather.
Titan has no water, but some scientists wonder if life based on methane might live on Titan.
Titan has a dense atmosphere of 95 percent nitrogen and 5 percent methane at 1.5 times the air pressure on Earth. Titan’s atmosphere is unbreathable, but if you were standing on Titan you would not need a pressurized space suit, only a breathing mask and protection from the cold. [See amazing photos of Titan]
