YR4 has a 2% chance of hitting Earth in 2032. Astronomers are tracking it to refine estimates of its size and orbit to see how much of a risk the space rock poses.

YR4 has a roughly 2 percent chance of hitting Earth in 2032, and “is large enough to cause localized damage,” NASA says.

"While still an extremely low possibility, asteroid 2024 YR4's impact probability with Earth has increased from about 1% to a 2.3% chance on Dec. 22, 2032," NASA shared on X. "As we observe the asteroid more, the impact probability will become better known."
