what if bennu hit earth

According to recent studies, there is a 1 in 2,700 chance that asteroid Bennu could hit Earth by September 24, 2182, which is almost 159 years from now. If this were to happen, Bennu would not destroy the Earth or all life on it, but it would leave a crater four miles wide and knock down nearby cities. The impact would also spawn an earthquake and a shockwave through Earths atmosphere, which together would likely damage buildings hundreds of miles away from the impact site. If Bennu were to hit Earth, it would release 1,200 megatons of energy, which is 24 times the energy of the most powerful nuclear weapon built by humanity. However, the chances of Bennu hitting Earth are still very low. NASAs OSIRIS-REx mission is studying Bennu to better understand its composition and orbit, and to help scientists better understand how to protect Earth if Bennus trajectory were ever to intersect with that of our planet.
