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

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

The moon had a fluctuating orbit around the Earth, but recent changes in distance could be caused by the tidal force shifting the planet’s mass.

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 ...
