WASHINGTON, Feb. 17 (UPI) -- An asteroid roughly 850 feet in diameter will pass by Earth tonight, and the spectacle will be broadcast live on the internet.
Scientists say the asteroid's trajectory puts it a safe distance away from Earth. But a space rock the size of three football fields traveling 27,000 mph this close to Earth is still quite the occurrence. At its closest point, scientists say, the asteroid will be roughly 9 lunar distances away, or a few million miles.
