Size comparison: Moon vs Titan

Size comparison between the satellite of the Earth, namely the Moon and Titan, the natural satellite of Saturn.

We notice that the Moon is a little smaller than Titan. Gravity on Titan is a bit lower. Its atmosphere is very rich in nitrogen. Whereas that of the Moon is very poor. Titan has lakes of liquid hydrocarbons, a surface similar to that of Earth, with coasts and dunes. Titan is reminiscent of an early version of Earth with a much lower temperature. It is assumed that this satellite presents microbial extraterrestrial life, or a prebiotic natural environment.

Note: if one of the objects is not visible, it just means that it is too tiny to be displayed compared to the other one.
