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

NASA's watchful eye on the skies has recently spotted asteroid Bennu, a celestial body with a slim chance of impacting Earth. According to a study published in Science Advances, Bennu's odds of striking are 1 in 2,

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,

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,

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.
