Yet there are exceptions; in the depths of the solar system, the moon Titan orbits the ringed planet Saturn. Titan is cold, far from the sun and seismically inactive. It has no magnetosphere and with a surface gravity of only 0.14 G should not be able to retain an atmosphere - yet it has a dense atmosphere that is 1.45 times thicker than that of Earth's Ganymede and Callisto, comparable-sized moons of Jupiter, are of a similar composition but do not have atmospheres. One theory suggests that Titan, being farther from the sun than the moons of Jupiter, was colder during its formation. Gasses were trapped in the ice at those low temperatures and later made their way into Titan's atmosphere.
