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 is tidally locked to Earth in synchronous rotation. This means that its rotation period (lunar day) and its orbital period (lunar month) are the same (29.5 Earth days), which keeps the same side of the Moon facing Earth. Conversely, the Moon's gravitation causes tidal forces on Earth, which are the main driver of Earth's tides. In geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.
