Massive dangerous asteroid Bennu not solid rock, like ball pit - NASA
The 500-meter Bennu is thought to be one of the most dangerous asteroids in the solar system. But rather than being solid rock, it turns out its surface is like a ball pit.
This mosaic of the asteroid Bennu was created using observations made by NASA’s OSIRIS-REx spacecraft that was in close proximity to the asteroid for over two years.(photo credit: NASA/Goddard/University of Arizona)ByAARON REICHUpdated:
