Model suggests asteroid Donaldjohanson formed 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 and spin properties have undergone significant evolution since.
