Résumé

Comet and Asteroid Impact Hazards on a Populated Earth presents the first computer simulations of the hazards of comet and asteroid bombardment of a populated Earth. Previous estimates of fatality and damage rates on the 100 to 10,000 year time scale are shown to be too low because they neglect rare, highly lethal outliers of the populations of bombarding objects, those with exceptional strength, unusually low entry velocity, and near-horizontal entry angles. This is the first realistic assessment of both the mean casualty rate and the expected statistical fluctuations in that rate. A breakdown of fatality and damage rates by impactor energy and compositional class suggests lessons for both asteroid search strategies and interdiction techniques.
