Yeomans takes readers behind the scenes of todays efforts to find, track, and study near-Earth objects. He shows how the same comets and asteroids most likely to collide with us could also be mined for precious natural resources like water and oxygen, and used as watering holes and fueling stations for expeditions to Mars and the outermost reaches of our solar system.

"Balancing the wonders of astronomy with the looming potential for an epic, planet-wide disaster, Yeomans, a fellow and research scientist at NASA´s Jet Propulsion Laboratory, explores the origins of near-Earth objects--asteroids, comets, meteors, and meteoroids--and the threat they can pose to our planet. . . . Yeomans´s book is an accessible and far-ranging primer on the science of near-Earth objects."--Publishers Weekly
