How radar helps detect asteroids

New NASA video reveals a moon on an asteroid that's flying by Earth tomorrow

If you're a fan of asteroids coming close to the Earth and not destroying life as we know it, circle tomorrow on your calendar. Asteroid 1998 QE2 will be closest to Earth tomorrow (by a mere 3.6 million miles or so)

In this video released today by NASA's Jet Propulsion Laboratory, radar has revealed the presence of a small moon (or a Death Star, we're still not sure) spinning around the asteroid. Take a look:

Earlier this week, the JPL produced this video, announcing the arrival of the QE2 (the asteroid, not the cruise ship), explaining how they use radar technology to detect and measure asteroids out there in the cosmos.

Seriously, have we all checked to make sure that the "moon" is not a space station? I have to go gas up the Falcon in case it is.
