Researchers using data from the Gaia mission’s third data release have found 3,038 binary asteroid candidates. These celestial pairs include an asteroid and a smaller moonlet. Using a novel ...

The first look at the Dinkinesh asteroid revealed a surprise: The small space rock had its own moon. Now as the Lucy spacecraft downlinked more images of its first target, it showed not one but ...

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.

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.

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 ...
