LOOK! The Asteroid That Flew Past Earth Tuesday Has Its Own Moon

In celestial terms, asteroid 2004 BL86 pretty much buzzed the Earth on Tuesday, coming within 745,000 miles of our planet.

As NPR's Sam Sanders explained, Monday's flyby is the closest a known asteroid of this size will pass by Earth in at least the next two centuries.

This means that when the asteroid flew by yesterday, scientists trained their instruments on the body.
