Asteroid 2024 YR4 initially had a small chance of hitting Earth in 2032, but NASA revised the probability to almost zero. However, observations now suggest a 2% chance of it striking the moon ...

Most of the time these asteroids remain restrained within that interplanetary belt by Jupiter's gravitational field, unable to coalesce into a larger body. But occasionally another asteroid or the ...

Ten years ago, astronomers from various institutions, including NASA and SETI (Search for ExtraTerrestrial Intelligence), set out to map the asteroid belt by tracking meteorites as they blazed ...

The Kirkwood gaps are explained by asteroids similarly interacting with Jupiter to leave the asteroid belt, even while their average distance from the sun does not change. By dipping into the ...

Interestingly, asteroid (20) Massalia, the parent of this family, is also an H chondrite type. Meteorites with less iron—called L and LL chondrites—mostly come from the inner asteroid belt.
