Astronomers have solved the mystery of a star that has baffled scientists for over a century, finding it is a cannibal white ...

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 ...

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

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.

Due to the influence the Earth plays on the moon’s momentum, the Earth’s rotation slows down in response, as explained by DiKerby. However, given that this is such a minor change in distance annually, ...

Most scientists agree that a major collision 4.5 billion years ago with a protoplanet named Theia formed the Earth-Moon system. Now, a new study from the University of Nevada argues that, out of the ...
