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

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

The moon's gravity causes high and low tides, something known as the tidal force. As the tidal force shifts Earth's mass, it ...

A new study has revealed that the Earth’s celestial companion, the Moon, is moving away from the Earth at the rate of 1.5 ...

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 ...
