Asteroid Donaldjohanson

Main belt asteroid 52246 Donaldjohanson is about 8 kilometers long and 3.5 kilometers across. The Lucy spacecraft's long-range camera captured this sharp close-up on April 20, from a distance of about 1100 kilometers. This elongated asteroid, named after paleoanthropologist Donald Johanson, likely formed around 150 million years ago from a gentle collision of two smaller bodies.
