Detailed Description

  1300 pgs, 1994, University of Arizona Press
  ISBN 978-0816515059

Documents the beginning of new discipline of detecting and mitigating hazards caused by comets and asteroids.

More than 120 authors collaborated on the volume's 46 chapters chronicling the development of the relatively new discipline of detecting and mitigating hazards caused by comets and asteroids. Topics range from detection to orbit prediction to impact avoidance to damage assessment, balancing historical information with speculation. Of special interest was comet/asteroid activity on or near Jupiter, which allowed study of impact effects from a safe distance. A massive volume with no photographs inside and few illustrations.
