The rocky object called Bennu is classified as a near-Earth asteroid, currently making its closest approach to Earth every six years at about 186,000 miles (299,000 km) away. It might come even closer in the future,

Bennu, which comes closest to Earth every six years at a distance of 299,000 km, has a one-in-2,700 chance of colliding with the planet.

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,

Near-Earth asteroid Bennu has a slim chance of colliding with Earth in 2182. If it does, the impact could trigger a global winter that affects our planet for years.

Bennu’s highly unlikely impact with Earth—which could happen in 157 years—could cause a global winter and drought, modeling suggests.
