The 3 Numbers That Decide Whether a Space Rock Is Dangerous

If an asteroid headline ever made you pause, this video gives you a simple way to judge the real risk: three numbers that decide everything — size, speed, and trajectory. 🚀☄️ You’ll learn why “close approach” doesn’t mean “impact,” why early impact odds can briefly rise before dropping, and how NASA/ESA tracking systems update risks as new observations tighten an asteroid’s path. We’ll also break down what the atmosphere changes, how warning time is the real superpower, and what a realistic planetary defense response looks like.
