We Never Know

One day a large one won't just pass by. Anyways..
An asteroid nearly a mile wide with a moon of its own is expected to pass by Earth this weekend, traveling at 48,000 mph. The space rock, known as asteroid 1999 KW4, was discovered 20 years ago and is so large that it is orbited by a moon.
On Saturday evening, 1999 KW4 will make its closest approach to Earth. It will be visible until May 27. Because it carries a large moon along with it, the asteroid is technically designated as a binary system.
