Keith talks to Peter Brown, Professor of Physics & Astronomy at the University of Western Ontario. What's the difference between a meteoroid, a meteor, and a meteorite? Peter also talks about some of the impact sites he's studied, and tells us about the 2013 Chelyabinsk event, in which a meteor exploded over Russia, and the resulting shock wave caused windows to blow out in the town of Chelyabinsk.
