New observations have dramatically reduced the chances of asteroid 2024 YR4 hitting Earth in 2032, lowering the risk to minimal levels, but its extraordinarily close approach will offer astronomers th

An asteroid between about 130 and 300 ft. (40 and 90 meters) in diameter has been given a 2.3% chance of it hitting Earth on Dec. 22, 2032.

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.
