Opis

This book presents the most recent research on the development of a reliable defense against objects that can potentially collide with the Earth. Large asteroids and comets can collide with the Earth causing severe consequences, and collisions are a random process that can occur at any time. To reduce the threat, it is necessary to understand these potentially hazardous objects.
