Preliminary studies of Lucy’s first images of the binary asteroid pair indicate that the bigger rock is about half a mile wide, while its satellite is about 0.15 miles wide.

NASA has discovered that an asteroid named Dinky is orbited by a tiny moon, forming a binary asteroid pair. In other words, it’s an even dinkier Dinky.

In studying data collected from NASA's DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission's ...

NASA’s Double Asteroid Redirect Test (DART) spacecraft launched from California last fall and zoomed through space to reach a binary asteroid system — the larger Didymos and its smaller ...

NASA’s Double Asteroid Redirection Test (DART) will crash into the asteroid Dimorphos on September 26th, 2022. The mission is the first planetary defense test, and will try to change the orbit ...
