On a lengthy voyage to Jupiter, NASA’s Lucy probe swoops past the first of ten asteroids.

On its arduous voyage to Jupiter, NASA’s Lucy spacecraft encountered the first of ten asteroids on Wednesday.

The tiny Dinkinesh was located in the main asteroid belt beyond Mars, around 300 million miles (480 million kilometers) distant, when the spacecraft zipped by it on Wednesday. NASA described the spacecraft’s passing at 10,000 mph (16,000 kph) as “a quick hello.”

Lucy tested its instruments on a dry run for the larger and more attractive asteroids ahead, approaching Dinkinesh to within 270 miles (435 kilometers) of the spacecraft. Dinkinesh, maybe the smallest space rock on Lucy’s trip, is only a half-mile (1 kilometer) across.

Lucy’s primary targets are a group of unidentified asteroids known as the Trojans that are believed to be
