Dust and other debris would rise into the atmosphere on Bennu striking Earth, blocking out the Sun and cooling the planet to devastating effect.

Although the chances of impact are slim, Bennu is still one of the most potentially hazardous known asteroids in our solar system, and we need to be prepared for what could come. A first-of-its-kind study simulated the planet-wide damage that would be caused by Bennu’s unlikely impact,

Asteroid Bennu, the size of the Empire State Building, has a small chance of hitting Earth in 2182, potentially triggering climate shifts, ocean changes, and global crises.
