Abstract

The volume contains the proceedings of the International Conference “Asteroid-Comet Hazard-2009” held in St. Petersburg, Russia, September 21–25, 2009. The conference was held in the Institute of Applied Astronomy of the Russian Academy of Sciences. The subjects of considerable discussion at the conference were the origin and physical nature of minor bodies of the Solar System that can collide with the Earth, detection and follow-up of such bodies and the devastating consequences of their collisions with planets and satellites. Special attention was paid to the dynamics of Earth approach of these bodies, predictions of dangerous collisions, and organization for protecting the Earth from collisions with dangerously large bodies (larger than about 25 m in diameter).

Papers presented in the Proceedings are of considerable interest for the Solar System science community and for all who are involved in study of small objects of the Solar System and in protecting the Earth against catastrophic collisions with celestial bodies.
