Planetary Defenders: Asteroids, Risks, Readiness

Planetary defense is not science fiction—it is risk management at a planetary scale. Planetary Defenders: Asteroids, Risks, Readiness examines how humanity detects, tracks, and prepares for objects that could threaten Earth, and why readiness matters even when probabilities seem small.
This book takes a preparedness-first lens. It explains how near-Earth objects are discovered, how impact risk is calculated, and why uncertainty—not certainty—drives defense strategy. Rather than dramatizing catastrophe, the focus is on coordination: science, policy, communication, and response planning working together before a crisis arrives.
Readers learn why early detection changes everything, how deflection differs from destruction, and why decision timelines matter more than raw technology. Case studies reveal how exercises, simulations, and international cooperation turn awareness into action.
This book explores:
• How asteroid risk is identified and assessed
• Why low-probability events demand preparation
• How deflection strategies actually work
• Where communication and governance shape outcomes
• Why readiness is a global responsibility
This book is for scientists, policymakers, emergency planners, and informed citizens. If protecting Earth requires planning before panic, this book explains how planetary defense becomes a discipline—not a reaction.
