Exam 1 Material- Fall 2008 Titan or Saturn VI is the largest moon of Saturn, the only moon known to have a dense atmosphere, and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found. The Cassini-Huygens robotic spacecraft mission arrived in Saturn in 2004 and is currently studying the chemical composition of this planet and its moons, including Titan. The following table and graphs summarize important information about this moon. Average surface temperature 93.7 K This temperature does not vary much during the day or the seasons (min ~90 K; max 94 K) Average surface pressure 1.47 bars The atmospheric pressure on Earth is close to 1 bar. Air density at ground level 5 kg/m 3 The air density on Earth is 1.2 kg/m
