NASA's Lucy spacecraft will soon travel by asteroid Donaldjohanson, which formed roughly 150 million years ago.

Donaldjohanson, a main belt asteroid, could be a relic of a cosmic collision that took place 150 million years ago.

New Southwest Research Institute-led modeling indicates the main belt asteroid (52246) Donaldjohanson may have formed about 150 million years ago when a larger parent asteroid broke apart; its orbit ...
