A small asteroid has been quietly following Earth’s orbit for decades—unseen, unbothered and, until recently, completely ...

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 ...

2025-PN7 is around 62 feet (19 meters) wide, and it’s between 2.8 million miles and 37.2 million miles away from Earth. It ...

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

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 ...

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 ...

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.

Historical observations of the Moon's motion, dating back to ancient civilizations, played a crucial role in the development of timekeeping and calendar systems. The Moon's orbital cycle can be ...

"It is incredible that modern telescopic surveys have the ability to detect such small objects up to millions of kilometers away." Half a dozen fragments of the moon may briefly orbit Earth at any ...

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