Question 1

What is the Asteroid Impact Simulator?

Accepted Answer

A free tool that lets you pick any place on Earth, choose a real or famous asteroid, and see what would happen if it hit — the crater, the fireball, the shockwave, and more, all shown on a real map.

Question 2

Is this scientifically accurate?

Accepted Answer

Yes! The math is based on real published science (Collins et al. 2005). But these are estimates for learning and fun — not emergency warnings.

Does it use real asteroid data?

Accepted Answer

It includes famous asteroids like the one that killed the dinosaurs, plus live data from NASA about real asteroids flying near Earth right now.

Question 4

Is the simulator free?

Accepted Answer

Totally free. It runs right in your browser — no downloads, no sign-ups, no payments.

Question 5

What asteroid killed the dinosaurs?

The Chicxulub impactor — a 12 km (7.5 mile) wide space rock that hit Mexico 66 million years ago. You can simulate it yourself on asteroidmap.com!
