Cosmic pinball

"Cosmic Pinball presents the latest scientific research on the rogue rocks: comets, meteors, meteorites, and asteroids."--BOOK JACKET. "From the minute grains of dust that every day sift down through our atmosphere, to the city-sized asteroids that sometimes swing perilously close to our vulnerable planet, Cosmic Pinball digs deep into the mysteries of the flotsam and jetsam left over from our solar system's violent birth."--BOOK JACKET.
