I'm largest moon of saturn and the second largest moon in the solar system; I was discovered in 1655 by Dutch astronomer Christiaan Huygens. I have the honor of being the only moon in the solar system with an atmosphere.-Christiaan Huygens-I'm roughly 50% larger than Earth's moon by diameter, and larger by diameter and mass than all known dwarf planets.-Your home Earth, Me [Titan] and your home planets moon-
I'm also covered in hydrocarbon lakes. Based on my bulk density of 1.88 g/cm³, my bulk composition is half water ice and half rocky material.-My hydrocarbon lakes-I'm the only known moon with a fully developed atmosphere that consists of more than just trace gases.My atmosphere is so thick, in fact, and my gravity is so low, that a human could fly through it by flapping "wings" attached to his arms!
