Asteroids

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.

Asteroid 2024 YR4 has a 2.3% chance of hitting Earth in the year 2032. But according to new estimates, it may have an even smaller chance of hitting the moon instead.

Astronomers have captured a new image of the asteroid 2024 YR4, which now has a 1 in 48 chance of hitting Earth in 2032.

Scientists simulated what would happen if a medium-size asteroid were to strike Earth. One of those space rocks, asteroid Bennu, has a 1-in-2,700 chance of hitting Earth in the year 2182.

The chances of the asteroid 2024 YR4 hitting Earth in 2032 appear to have doubled, but an asteroid hunter explains to Space.com why this isn't cause for concern.
