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.
As the moon induces tides on Earth, the planet rotates faster than the moon orbits and the tidal bulges get âaheadâ of the moon. They then pull forward on the moon, causing it to gain orbital energy and move away from Earth.
