The asteroid, called 2024 YR4, is roughly 130 to 300 feet across. It was first reported on Dec. 27, 2024, by the NASA-funded Asteroid Terrestrial-impact Last Alert System station in Chile. Its impact probability will be refined as more data is collected. It could be ruled out entirely, or it might see its impact probability rise, according to NASA.

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