coolthingoftheday: Titan, also known as the mermaid moon, is the largest satellite of Jupiter. It is the only known moon in our solar system that has a dense atmosphere, and the only object other than Earth where evidence of surface liquid has been found; however, the liquid on Titan is made of methane, not water.
