A nearly 98 percent chance it won’t hit us is pretty good. Second, while that’s definitely a massive rock, it’s not like a dinosaurs-killing size. Three hundred feet wide is about on par with the asteroid that exploded over Siberia in 1908 (also known as the 1908 Tunguska Event).

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.
