Experts from NASA and other international organizations recently simulated their response to a hypothetical asteroid impact scenario. The test was deemed a success. However, several media outlets have misreported the group's findings.

A new public competition will allow a lucky astronomy enthusiast to name one of Earth's tiny "quasi-moons." Here's everything you need to know about how to enter the competition for free.

Scientists have calculated the rotational speed of asteroid 2024 BX1, which exploded over Berlin earlier this year, by letting it trail in images of the sky. It turns out, 2024 BX1 was spinning faster than any other near-Earth object ever seen.

The near-Earth asteroid Kamo'oalewa, which orbits alongside our planet as a 'minimoon,' may have originated from Giordano Bruno crater on the far side of the moon, new research suggests.

The 2,000-foot-wide asteroid 2013 NK4 just made its closest approach to Earth in recorded history, sailing by at about eight lunar distances. You can still see the massive rock with a backyard telescope.

A newly discovered asteroid got within 12,000 miles of Earth on a harrowing, ultra-close approach today. The space rock won't return for 70 years.

Dozens of boulders dislodged by NASA's asteroid-smashing DART test could hit Mars in the future, new research suggests.

Scientists shared the first comprehensive science results from NASA's OSIRIS-REx asteroid-sampling mission at the Lunar and Planetary Science Conference, revealing the out-of-this-world makeup of asteroid Bennu.

Why do some celestial bodies have tadpole or even horseshoe-like orbits?

Scientists detected water molecules on the surface of two asteroids for the first time ever. The team made the discovery using data from NASA's now-retired SOFIA airborne observatory.
