The NASA mission's first close flyby came with an exciting surprise: Dinkinesh is a binary asteroid featuring not one but two space rocks.

NASA’s Lucy mission flew by the asteroid Dinkinesh this week, and the images it captured revealed not one but two space rocks.

The binary consists of a larger, primary asteroid and a smaller “moon” orbiting around it, as seen in images that Lucy captured of the pair.

The small moon, which is the first contact-binary satellite found orbiting an asteroid, was spun off its parent space rock.

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.

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

New images released from NASA’s mission to intentionally collide with an asteroid in 2022 have revealed information on the origins of the asteroid system.

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