No, Bennu Is Not Going To Kill Us All

 No, NASA has not confirmed that asteroid Bennu will hit us on September 24, 2182.

Bennu has a 1 in 1,750 chance of hitting the Earth by the year 2300 and a one in 2,700 chance of specifically hitting on that date (although it is the most likely).

Bennu is 500 meters across. The asteroid that killed the dinosaurs was 6 miles across. So, while Bennu hitting would be bad, it wouldn't kill us all.

What it would do is create a four mile wide crater, knock down buildings tens of miles away and shatter windows 100 miles away. So if it were to hit, say, Los Angeles, we'd have a real life disaster movie.

We're also developing planetary defense systems and if Bennu does start to get too close we should be able to, shall we say, convince it to go somewhere else. If not, we'd likely get enough warning to evacuate the impact site, or coastal areas that might be tsunami'd by a water impact.

(And in any case, 2182 is a while in the future).
