  • But why can't other nations send missiles to hit 1-2km asteroids by tracing it's trajectory when they are closer to Earth(Like when they are just above Earth surface) It will atleast minimize the focused damge ryt? 🤔🤨🧐

  • Nuking an asteroid should not be disregarded. I believe it's the most viable approach and doing in near proximity to Earth's atmosphere would prevent the chunks from clumping back together, allowing a greater surface area of Earth's atmosphere to burn the chunks.
