How Many Moons Does Earth Have?

This short piece from NPR reports some research from one of the astronomers where I used to work:  Earth Has Just One Moon, Right? Think Again

I love this line:  "Mostly these {asteroids} go whizzing by, not even slowing down to wave."

The Long, Twisted Path To Mercury video is interesting, too - what a crazy concept, what a wild ride.
