This is the story of how the collision of asteroids and comets with our planet have changed the course of life on Earth. A massive impact wiped out the dinosaurs and many other species 65 million years ago. Will humans suffer the same fate? If we discover an asteroid or comet on a collision course with Earth, will we be able to do something to save ourselves? In his usual lively, clear style, Dr. Fred will provide the scientific information that young readers will need to understand and follow these questions to interesting conclusions.
