Don’t worry. You’ll long be dead before that has any chance of happening. So will your children. Probably all of your grandchildren, too.

At a news conference Wednesday, NASA scientists said there was a 1-in-1,750 chance that an asteroid named Bennu, which is a bit wider than the Empire State Building is tall, could collide with Earth between now and 2300.
