A newly discovered asteroid the size of a city bus gave Earth a close shave this morning (Dec. 19), zipping well within the orbit of the moon.
The near-Earth asteroid 2015 YB, which is about 34 feet (10 meters) wide, cruised within a mere 36,800 miles (59,220 kilometers) of the planet at around 7 a.m. EST (1200 GMT) today, just two days after the space rock was first spotted.
