The Moon, unlike Earth, lacks an atmosphere to absorb or deflect impact debris. A direct hit from YR4 could create a crater nearly 1 kilometer (0.6 miles) wide, comparable to Arizona’s Meteor Crater.

The first asteroid, officially named (2025 OJ1), is estimated to be around 300 feet wide, while the second is 2019 CO1, sizable at around 200 feet.

NASA has detected two large near-Earth asteroids, named 2025 OA3 and 2025 PA, both set to make their closest approach to our ...

About 40% of near-Earth space rocks larger than 140 meters (460 feet) but smaller than a kilometer — capable of more widespread destruction — have been identified, according to NASA.

NASA has detected two near-Earth asteroids, named 2025 OA3 and 2025 PA. These space objects will make their closest approach on August 4.

The new statistics, crunched by NASA’s Center for Near-Earth Object Studies, still suggest the asteroid is much more likely to miss it. Even if it were to make contact, it wouldn't cause a ...

Scientists are monitoring a recently discovered asteroid which could potentially hit the Moon - and calculating its likely consequences on Earth.

A plane-sized asteroid scheduled to pass Earth next week is making headlines, but NASA experts want the public to understand why this encounter is more routine than remarkable.

Asteroid 2024 YR4, which once appeared to be on a collision course with Earth, may hit the moon, which could create some problems for our planet.
