The world is watching as NASA tweaks the odds that asteroid 2024 YR4 will hit Earth. But how threatening is YR4, and how does it compare to other potentially hazardous space rocks?

While the asteroid's possibly collision with earth wouldn't be until 2032, there's been a lot of talk about the possibility in recent weeks.

Don't worry. Asteroid 2024 YR4 now has a 99.72% chance of missing Earth in 2032. If you've been worrying about reports of a possible asteroid impact in 2032, we have very good news. NASA has dropped the probability of an impact from asteroid 2024 YR4 — at first to 1 in 67, and now to 1 in 360.
