Today we went to see the moon's craters such as you have, we explored whether there is life, etc.The Moon is the only Natural satellite of the Earth and the fifth largest moon in the Solar System. It is naturally the largest satellite of a planet in the Solar System relative to the size of its primary, having 27% the diameter and 60% the density of Earth, resulting in 1/81 it's mass. Among Known satellites with densities, the Moon is the second densest, after Io, a satellite of Jupiter.
