The
Moon is an astronomical body that orbits planet
Earth and is Earth's only permanent natural satellite.
It is the fifth-largest natural satellite in the
Solar System, and the largest among planetary
satellites relative to the size of the planet
that it orbits (its primary).
The
Moon is after Jupiter's satellite Io the second-densest
satellite in the Solar System among those whose
densities are known.
Moon
age
The
Moon is thought to have formed about 4.51 billion
years ago, not long after Earth. The most widely
accepted explanation is that the Moon formed from
the debris left over after a giant impact between
Earth and a Mars-sized body called Theia.
