NASA's Lucy mission is on its way to Jupiter's Trojan belts to examine a collection of objects in the region. But its path brought it close to another asteroid in the main belt: Dinkinesh. The spacecraft flew past the asteroid on Nov. 1st, coming within 270 km. Mission controllers were surprised to discover the asteroid had a tiny moon. When Lucy was planned, they hoped it would fly past seven asteroids, but new objects have been discovered, bringing the total to 11.
