For billions of years, asteroids have pursued their silent paths around the Solar System. From time to time, these paths, disrupted by close encounters with larger bodies, end in collision. We now know that Earth is not immune to such cosmic encounters. From the dinosaur-ending Chicxulub impact to the multi-megaton Tunguska explosion of 1908 and the Chelyabinsk airburst of 2013, we have had plenty of warnings of what an asteroid impact can do.
This concise 12,000 eBook short read explores the science, history, and future of hazardous asteroids, and the solutions humanity is developing to avert potential catastrophe.
