The odds that asteroid 2024 YR4 could hit Earth in 2032 recently spiked from a little more than 1% to 2.3% as more observations are made.

An asteroid that's big enough to wipe out a city has a 1-in-43 chance of hitting our planet in the year 2032. But according to new calculations, there's an even smaller chance that it might crash into the moon instead.

Even the smallest odds of an impact sound alarming, but scientists’ ability to calculate them is actually good news.
