NASA has detected an asteroid called 2024 YR4, which has a 1 in 83 chance of impacting Earth in 2032, potentially releasing 8 megatons of energy and devastating a major city, although it's too small to end human civilization.

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.

Researchers say there’s a 1.3 percent chance that the space rock 2024 YR4 could strike our planet — but not until December 2032.
