Planetary Society Weekly Hangout: Studying Asteroids from Earth with Andy Rivkin

Join Emily Lakdawalla for the Planetary Society's weekly hangout! Her guest this week was Applied Physics Laboratory asteroid astronomer and occasional musician Andy Rivkin. We talked about the menagerie of rocks in the asteroid belt, how many of them travel in pairs and triples, how some of them are surprisingly wet, and how much you can learn about asteroids using Earth-based telescopes.
