Bennu might hit Earth in 2182.
"When I saw the images of Dimorphos, it looked really familiar; it looked like a bouldery pile of rubble with that same kind of characteristic texture," Dante Lauretta, the OSIRIS-REx principal investigator at the University of Arizona, told Space.com."The [DART] mission was phenomenally successful.
OSIRIS-REx's in-depth investigation of Bennu from orbit also revealed that the rocks towering on the asteroid's surface are made of a very porous, sponge-like material. This porosity, scientists think, may be"It's like a crumple zone in a car," Edward Beau Bierhaus, an OSIRIS-REx research scientist at Lockheed Martin, which built the OSIRIS-REx spacecraft for NASA, told Space.com.
As a result, there are fewer craters on Bennu's surface than scientists expected based on their knowledge of how common asteroid collisions have been throughout the history of the solar system.
