Publisher's Synopsis
Cosmic collisions have forever shaped the planets in our solar system. These are still happening, as we saw in July 1944 when a large comet was observed to hit Jupiter. A cosmic collision may have wiped out the dinosaurs 65 million years ago. What would happen if a similar collision occurred today? Scientists have just begun to track asteroids and comets to try to predict if such a collision is likely to happen.;This book looks at how often the Earth experiences a cosmic collision, how scientists can predict these collisions, how likely a collision is in the near future and how we can defend ourselves.
