The 2024 YR4 asteroid, which is nearly the size of a football field, now has roughly a 0.004% chance of hitting Earth in about eight years, according to the space agency's latest calculations. The Center for Near-Earth Object Studies previously projected a 3% chance of the asteroid striking our planet before lowering the chance to 0.28% last week.

YR4 has a 2.3% chance of hitting Earth in the year 2032. But according to new estimates, it may have an even smaller chance of hitting the moon instead.
