An asteroid that measures up to 300 feet across could smack into Earth in 2032, and while NASA says the chances of a collision are “extremely low,” the probability has been increasing since the space rock was discovered weeks ago.

We asked experts at NASA and the Massachusetts Institute of Technology what scientists know about the asteroid that could possibly impact Earth in December 2032.

The odds that asteroid 2024 YR4 could hit Earth in 2032 recently spiked from a little more than 1% to 2.3% as more observations are made.
