Earth probably has more than one moon

The BBC has an non-article (with its usual unbloggable video) by Pierangelo Pirak about our second Moon (technically, an asteroid known as 2006 RH120):

Our planet only has one permanent natural satellite, the Moon. But it often picks up other orbiting rocks.

Rico says space continues to be even more amazing than we can imagine...

(To be fair, the BBC did provide links to two serious articles on other Moons, here and here.)
