BRIAN WILLIAMS, anchor: If you felt a whoosh today, felt a little breeze, felt like maybe a truck drove by very quietly, there's a reason for it. Two asteroids, 11 hours apart, passed between the Earth and the moon today. In space terms that's like threading a needle. It's an eyelash. It's just 250,000 miles. They were only discovered en route to us on Sunday, thanks for all the advanced notice. And these are hardly pieces of space dust. The largest of these two asteroids was estimated to be 65 feet wide. That's big enough to leave a mark.
