The space rock is heading in our direction at some 18,700 miles per hour, according to the space agency's data.

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.

YR4 has a roughly 2 percent chance of hitting Earth in 2032, and “is large enough to cause localized damage,” NASA says.
