On April 20, the over 50-foot-wide Lucy spacecraft approached as close as some 600 miles from Donaldjohanson, which is aptly named for the discoverer of the famed Lucy hominid fossil, paleoanthropologist Donald Johanson. The craft sped by at 30,000 mph, and used a specialized camera to capture a detailed view of the five-mile-wide asteroid.

NASA’s Lucy spacecraft successfully flew past asteroid Donaldjohanson, collecting data and images of the second of its 11 targets as it heads deep into the solar system.

The team was surprised by the odd shape of the narrow neck connecting the two lobes, which looked like two nested ice cream cones.
