The Largest Moon Of Saturn: Titan
When the Voyager 1 and 2 spacecraft flew by Saturn in 1980 and 1981, they were able to pay only fleeting attention to Titan, the second largest moon in the solar system (larger even than the planet Mercury) and the only solar system moon with an appreciable atmosphere. These images are from subsequent Titan flybys in 2005 and 2006. (Image credit: NASA)
Titan is the only object other than Earth where clear evidence of stable bodies of surface liquid has been found. This beautiful cloudy Moon its the largest natural satellite of Saturn and the second largest moon in the Solar System, after Jupiter's moon Ganymede. (I know, I wrote Moon 4 times)
