Luna

The Moon, Earth's only natural satellite, lacks an atmosphere and has gravity that is one-sixth of Earth's. It is the largest satellite relative to the planet it orbits in the solar system. The Moon likely formed from a collision between Earth and a small planet-sized object around the same time as Earth.
