The destructive power of asteroids is undeniable — just ask the dinosaurs. New research suggests a huge space rock that struck Earth over 3 billion years ago may have benefitted early life.

Saturn has finally joined the solar system's other giant planets in possessing a Trojan asteroid, but it may have stolen it. The bouncing asteroid seems to have originated in the Kuiper belt.

Scientists say they've uncovered where the vast majority of Earth's meteorites came from.

The Taurid Meteoroid Stream, responsible for two November meteor showers and possibly the Tunguska and Chelyabinsk impacts, probably doesn't hide a civilization-killing asteroid, a new study finds.

Material harvested from asteroids could be used to sustain astronauts during long-duration space missions.

Scientists calculated that, on Sunday (Sept. 29), our planet should have captured the asteroid 2024 PT5, claiming it as a very temporary "mini-moon."

Radar images have captured snowman-shaped 2024 ON asteroid tumbling through space.

Scientists have found nuclear weapons could actually help deflect an incoming cosmic impact — not by blowing an asteroid up, but by showering it with X-ray radiation.

A chance encounter with another asteroid could steer Apophis destructively close to Earth during a future passage.
