Earth has a number of mini-moons and quasi-moons. Mini-moons are objects that orbit our planet. But they make for fickle fans: They tend to swing around Earth for only a matter of months. One example ...

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 ...

For more than sixty years, a tiny asteroid has been moving in step with Earth, hidden from view until recently. Astronomers ...

Astronomers have found yet another quasi-moon companion of Earth in its orbit around the Sun believed to be a chunk of our ...

In a new study published in the journal Research Notes of the American Astronomical Society, astronomers report the discovery ...

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

A recently observed object called 2025 PN7 was found orbiting near the Earth. The quasi-moon is expected to accompany our planet in a similar orbit for 60 years.

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, ...

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

On Aug. 23, 1966, NASA's Lunar Orbiter 1 sent back the first photo of Earth from the moon. It showed a grainy crescent Earth ...
