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 ...

DART slammed into Dimorphos at more than 14,000 miles per hour, its camera transmitting a final, partial image of the asteroid’s cobbled surface just before the impact. The strike sent a dusty ...

The first such “binary asteroid” was discovered when NASA’s Jupiter-bound Galileo probe flew by the 60-kilometer-long asteroid Ida in 1993 and spotted Dactyl, a smaller 1.6-km wide orbiting ...

Since the DART spacecraft smashed into asteroid moonlet Dimorphos, changing its orbit and shape, five published papers have explored the geology of the binary asteroid system.

The chance to also learn how binary asteroids form was the icing on the cake. Quite a few binary asteroid systems have been discovered, but planetary scientists don’t exactly know how they form.

A solar radiation-triggered quake likely caused the asteroid Dinkinesh to lose material. Some of it became a moon that now orbits the space rock, new research found.

Scientists may have learned the history of the tiny contact-binary moon orbiting asteroid 152830 Dinkinesh, which was the first cosmic stop for NASA's Lucy spacecraft. That moonlet may have spun ...

Scientists may have learned the history of the tiny contact-binary moon orbiting asteroid 152830 Dinkinesh, which was the first cosmic stop for NASA's Lucy spacecraft.

The asteroid that NASA flung a spacecraft into was deformed by the collision, but it appears to have reshaped itself and healed. The asteroid, named Dimorphos, was slammed into by NASA's Double ...
