Originally Answered: Why is the Moon drifting away by 1 cm each year? Because of tidal forces between moon and Earth. As Earth and moon pull each other, bulges are created on the surface.
The Moon (Latin: luna) is Earth's satellite, and we can usually see it in the night sky. Other planets also have moons or natural satellites. Our moon is about a quarter the size of the Earth. Because it is far away it looks small. The gravity on the moon is one-sixth of the Earth's gravity. It means that something will be six times lighter on the Moon than on Earth. The Moon is a rocky and dusty place. The Moon drifts away from Earth at the rate of four centimeters each year.
