NASA's OSIRIS-REx mission reached asteroid 101955 Bennu. Two years later, the spacecraft snagged a sample of its surface, which has since been returned to Earth. Now, astronomers are getting to know Bennu like never before - and a new study looks at how it could wreck us.

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.

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,
