Learn more about tides and tidal bulge, and how they’re contributing to the moon drifting away.

The Moon is slowly receding from Earth at 1.5 inches per year due to tidal forces. This celestial dance also causes Earth's ...

Tides come from a difference in gravity across an object. The force of gravity exerted by the Moon is about 4% stronger on the side of Earth that faces toward the Moon, compared to the opposite side ...

Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its ...

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...

Long ago, the Moon was much nearer Earth. Scientists believe a protoplanet collision created the Moon 4.5 billion years ago.

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...

Every year, the moon, Earth's reliable celestial companion for 4.5 billion years, is getting 1.5 inches away. The distance to ...
