Earth’s path around the Sun is not a fixed racetrack but a slowly shifting orbit, and those subtle changes have a long history of reshaping the planet’s climate. As astronomers refine how these ...

Scientists are beginning to read Earth in a different way, not from orbit, but from the surface of the moon. A recent study, ...

On its own, Earth would shift toward another ice age in about 10,000 years, scientists say. But humanity’s greenhouse gas emissions may have radically shifted the climates trajectory. (Santa Barbara, ...

The Earth's next ice age is expected to begin in about 11,000 years -- unless human-caused global warming disrupts natural cycles. That's according to a new study published Thursday in Science, which ...

A major asteroid has entered Earth's orbit, and some scientists and experts believe it is exhibiting behavior consistent with what we know as the moon. This discovery has led some to report that a ...

Asteroid 2025 PN7 orbits Earth similarly to the moon but is a quasi-satellite. The asteroid poses no threat and will never come closer than 4 million kilometers to Earth. Other quasi-satellites ...
