NASA officials have discovered a new asteroid that has a small chance of hitting Earth in December 2032. The near-Earth asteroid has been named 2024 YR4 and is estimated to be 40 to 90 meters wide.

Chilling animations depict the apocalyptic impact that “city-killer” asteroid YR4 2024 could have if it did hit Earth — while astronomers warn that the moon could be in the line of fire as well.

NASA scientists used satellite measurements to map out local subsidence and uplift across the Golden State, which plays into local sea level changes.

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