Look at it this way — there's almost a 99 per cent chance an asteroid up to the size of a football field won't hit the Earth in eight years. Still, there's up to a two per cent chance it will, according to NASA and the European Space Agency (ESA).

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

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.

"An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the European Space Agency said.

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,

It's actually good news that NASA spotted a sizable asteroid with a (small) chance of hitting Earth in 2032. It means our asteroid-sleuthing telescopes are working.
