☄️ Defend Earth — Asteroid Impact Simulator
Incoming! Asteroids are heading toward Earth and you're the last line of defence. Aim your cannons and deflect or destroy the threats before they reach the surface!
🔬 What It Demonstrates
Real asteroid deflection uses kinetic impactors (crashing a spacecraft into the asteroid) and gravitational tractors (hovering spacecraft slowly altering its orbit). Even a tiny velocity change years in advance shifts the orbit enough to miss Earth.
🎮 How to Use
Click or tap to aim at incoming asteroids. Larger asteroids need more hits to destroy. Some move faster than others — prioritise the biggest and fastest threats!
💡 Did You Know?
NASA's DART mission crashed a spacecraft into asteroid Dimorphos in September 2022 — and it worked! The impact changed Dimorphos's orbital period by 32 minutes, proving asteroid deflection is possible.
