For many years Titan has inspired the thoughts of astronomers and cosmologists the world over. Titan is bigger than Mercury and is the holder of that rare thing, an atmosphere.

Titan is 5,150 km (3,200 miles) across and its size affects the orbits of other near-by moons. Titan hides its surface with a dense nitrogen saturated atmosphere which is approximately 95% nitrogen. Earth’s atmosphere extends about 60 km (37 miles) into space while Titan’s extends 600 km into space.

On the 14th January 2005 the Cassini space mission passed by Titan and released an investigative probe to drop down into the moon’s atmosphere and finally reveal what exactly lay beneath the smoggy orange glow of this fascinating moon. Among other things revealed by the mission was the audio data which was collected by the Huygens Atmospheric Structure Instrument (HASI) during the Huygens probe’s descent into Titan’s murky atmosphere.

Phoebe orbits Saturn in the opposite direction of Saturn’s large moons.

Enceladus has been reported to have volcanic activity with evaporating ice escaping from the surface.

Hyperion has a flat shape and a chaotic rotation.

Pan travels through the main rings of Saturn and creates a space known as the Enche Gap.
