Asteroids

On Easter Sunday (April 20), NASA's Lucy probe should have zipped past the asteroid Donaldjohanson, testing science instruments on the space rock.

A Q&A with Lindley Johnson, a pioneer in blueprinting warning and response scenarios to any potential impact of Earth by an asteroid or comet.

Asteroid 2024 YR4, once a potential Earth threat, likely originated from the main asteroid belt's central region, a surprising origin for Earth-crossing space rocks, a new study finds.

The near-Earth asteroid 2025 BC10 will pass safely near our planet on Saturday (April 5). The Virtual Telescope Project will livestream views of the asteroid's close approach online.

NASA's Lucy spacecraft will soon travel by asteroid Donaldjohanson, which formed roughly 150 million years ago.

Despite a brief panic, asteroid 2024 YR4 isn't likely to hit us anytime soon, but we can still study the asteroid up close to help us understand these space rocks.

The solar system could be packed with 1 million alien visitors, space rocks shaken away from our cosmic neighbor Alpha Centauri, new research has revealed.

Observations from the European Southern Observatory's Very Large Telescope helped show that the expected trajectory of asteroid 2024 YR4 poses nearly zero risk of impacting Earth in 2032.

The chances of asteroid 2024 YR4 hitting our planet are now zero. Last week, it was the riskiest asteroid to hit our planet since records began.

Breathe a sigh of relief! NASA has dropped the risk of asteroid 2024 YR4 impacting Earth in 2032 to 1 in 360, just days after it became the highest-risk asteroid since records began.
