NASA has released new detailed images revealing a full-frame view of the peculiarly shaped asteroid Donaldjohanson.

The first flight mission for planetary defense, NASA's Double Asteroid Redirection Test (DART) seeks to validate a method to protect Earth from the threat of an asteroid impact. By smashing a ...

This time-lapse animation strings together a series of individual images of asteroid Donaldjohanson, as seen by the Lucy spacecraft during its close flyby. The asteroid has a smooth, light-grey ...

NASA's Double Asteroid Redirection Test (DART) spacecraft prior to impact at the Didymos binary asteroid system shown in this undated illustration handout.

Neither body posed a threat to Earth, but the binary asteroid system was close enough to Earth for the impact to be studied by observatories on the ground.

Yes, just like larger planets, asteroids can have moons, too! The fact that asteroids can have satellites at all came as something of a surprise. The first such “binary asteroid” was ...

But this discovery shows that there are many asteroid moons out there just waiting to be found." These 352 newly discovered binary asteroids nearly double the known tally of pairs like this in our ...

New data about binary asteroids comes from ESA's Gaia mission, a space-based telescope which has spotted new potential moons around 350 asteroids.

That conclusion reinforces the prevailing theory that some binary asteroid systems arise from shed remnants of a larger primary asteroid accumulating into a new asteroid moonlet.

New research using data and images collected during the DART mission has been used to further understand the origin and formation of the binary asteroid system.

The Didymos asteroid, and its tiny moon Dimorphos, are what’s known as a binary asteroid system. They were the perfect target for the DART mission, because the effects of the impact could be ...
