’s Lucy spacecraft this week had a big surprise for scientists. It turns out that the asteroid Dinkinesh has a dinky sidekick — a mini moon. The discovery was made during Wednesday’s flyby of Dinkinesh, 300 million miles away in the main asteroid belt beyond Mars. The spacecraft snapped a picture of the pair when it was about 270 miles out . In data and images beamed back to Earth, the spacecraft confirmed that Dinkinesh is barely a half-mile across.
