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 pull of the moon is also slowing the Earth's rotation, an effect known as tidal braking, which increases the length of our day by 2.3 milliseconds per century. The energy that Earth loses is picked up by the moon, increasing its distance from the Earth, which means the moon gets farther away by 1.5 inches (3.8 centimeters) annually.
