Over the next several weeks, astronomers will be looking closely at an asteroid called 2024 YR4 that could be as big as a football field as they try to determine how likely it is to strike Earth in 2032.

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.

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.
