Scientists have, in fact, spotted one candidate: Bennu, which has a small chance of banging into our planet in the year 2182. For almost 20 years, a team of researchers has been preparing for such a scenario. Using a specially designed gun, they've repeatedly fired projectiles at meteorites and measured how the space rocks recoiled and, in some cases, shattered.
