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 Earth stands alone in the solar system as a habitable world, as far as we know. But that doesn’t mean we don’t get visitors, most often in the form of (usually harmless) asteroids. Some even ...

Asteroid 2024 YR4 currently has a 4% chance of smashing into the Moon in about seven years. Astronomers are already working ...

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

Earth asteroid lurked undetected for decades until a telescope in Hawaii spotted it earlier this year. It may be Earth's ...

Everyone who has ever lived on Earth has been well-aware of the moon, but it turns out Earth also has some frequent temporary companions. These "quasi-moons" are small asteroids that enter into a kind ...

The region where the gravitational influence of Earth is the dominant force, is called the Hill Sphere. This extends up to ...

The Artemis II mission is part of NASA’s plan to resume deep-space exploration. In the Artemis I flight in 2022, an SLS ...

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 ...
