Bennu is one of the most hazardous known asteroids in our solar system. Thanks to a visit by a NASA spacecraft, scientists have a much greater understanding of the near-Earth asteroid, its upcoming closest approaches to Earth -- and whether it could impact our planet.
The data collected by NASA's OSIRIS-REx mission over two yearsnallowed for precision tracking of Bennu's movements through 2300, reducing the uncertainties scientists had about the asteroid's future orbit. The findings show Bennu has a 1 in 1,750 chance of impacting Earth through 2300 -- higher than previously thought.
Prior to OSIRIS-REx visiting and studying Bennu, researchers thought the overall probability of Bennu impacting Earth through 2200 was 1 in 2,700.
