The Moon is Earth's only natural satellite. It orbits around Earth at an average distance of 384399 km (238,854 mi; about 30 times Earth's diameter). The Moon rotates, but keeps facing Earth with the same near side. This tidal locking results from Earth's gravitational pull having synchronized the Moon's rotation period (lunar day) to its orbital period (lunar month) of 29.5 Earth days. Conversely, the gravitational pull of the Moon on Earth is the main driver of Earth's tides. In geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.
