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.

NASA is monitoring a 300-foot-long asteroid called the 2024 YR4. The chances of a collision are low but NASA said there is a 2.3% chance that the asteroid will hit Earth in 2032. NBC News’ Kathy Park reports on what experts are saying.

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.
