We found out that it has a dense atmosphere. The moon is currently undergoing study by the Cassini-Huygens mission, and new information about it is accumulating, such as the discovery of liquid hydrocarbon lakes near its north pole. These are the only large, stable bodies of surface liquid known to exist anywhere other than Earth.
Titan is never visible to the naked eye, but can be observed through small telescopes (diameter greater than 5 cm) or strong binoculars. It has a maximum magnitude of +7.9, which is outshone by six asteroids (Vesta, Pallas, Iris, Hebe, Juno, Melpomene) and the dwarf planet Ceres. Titan reaches an angular distance of about 20 Saturn radii from Saturn and subtends a disk 0.8 arcseconds in diameter.
