When I think of the eclipse I think of Titan, the second Largest moon in the Solar system. It has a thick atmosphere and appears to be twice the size of the moon but it not quite twice the mass though.
It is quite interesting because it isn't the biggest moon in the solar system but it has an atmosphere that is thicker than earth's. It also has liquid methane oceans and coastlines and mountains. I often wonder why Ganymede is much bigger than Titan but it has a thin atmosphere.
