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

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 ...

Astronomers have identified a tiny quasi-moon, 2025 PN7, orbiting near Earth for about 60 years. This 62-foot-wide near-Earth ...

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

A recently observed object called 2025 PN7 was found orbiting near the Earth. The quasi-moon is expected to accompany our ...

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 ...

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 ...

The Mainichi Shimbun answers some common questions readers may have about the mechanisms behind lunar and solar eclipses, as ...

"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 ...
