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 is spiraling away from the Earth at an average rate of 3.8 cm (1.5 in) per year, as detected by the Lunar Laser Ranging Experiment. By coincidence, the diameter of corner cubes in retroreflectors on the Moon is also 6998380000000000000â 3.8 cm. Distance between the Earth and Moon - sizes and distance to scale.
