asteroid

A newly discovered object, dubbed A11pl3Z, appears to be moving too fast and straight to have originated in the solar system. If confirmed, it will be the third interstellar visitor ever spotted.

There is currently a 4.3% chance that the giant space rock 2024 YR4 will hit the moon in seven years. If this does happen, debris from the nuclear bomb-like impact could trigger a "spectacular" meteor shower that will endanger Earth-orbiting satellites.

A new image released by China's space agency offers the first glimpse at the Tianwen 2 spacecraft, which is en route to collect samples from one of Earth's "quasi-moons". The photo shows some surprising similarities with a current NASA probe.

Vesta, thought to be the second-largest asteroid in the solar system, could be a piece of an ancient, unknown planet, a new study hints.

The dinosaurs were not in decline before the asteroid hit, a new study finds. Instead, poor fossilization conditions and unexposed late Cretaceous rock layers mean they're either not preserved or hard to find.

NASA has released the Lucy spacecraft's first close-up images of asteroid Donaldjohanson, revealing a peanut-shaped rock that could shed light on how planets formed in our solar system.

The once-dubbed "city-killer" asteroid 2024 YR4 has surprised scientists with its 'unusual' shape as it rapidly rotates through space on a trajectory that could see it hit the moon.

The hefty space rock 2014 TN17 is large enough to wipe out a city, but it will pose no risk to our planet when it sails by this Wednesday (March 26). Researchers will monitor it carefully during its close approach.

Buried "megaripples" — some the size of five-story buildings — are helping scientists piece together the devastation following the impact that wiped out the nonavian dinosaurs.

The likelihood of asteroid 2024 YR4 hitting Earth in 2032 rose and fell last week. NASA's impact odds are now so slim that the asteroid is no longer a hazard on the Torino asteroid scale.
