The Moon is Earth's only natural satellite. It orbits around Earth at an average distance of 384399 km (238854 mi; about 30 times Earth's diameter). Its orbital period (lunar month) and its rotation period (lunar day) are synchronized at 29.5 days by Earth's gravity pulling on the Moon. This makes the Moon tidally locked to Earth, always facing it with the same side. Conversely, the Moon's gravitational pull produces 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.
