Drop real asteroids.
See the destruction.
NASA JPL data. Collins et al. 2005 impact physics. MapLibre GL globe. Open source.
Asteroid Map is an interactive impact simulator built on real science — select any near-Earth asteroid from NASA's CNEOS catalog, click anywhere on the globe, and watch destruction zones render in real time using the same physics framework as Purdue University's Impact Earth tool.
Real data. Real physics. Real globe.
Full interactive 3-D globe. Users click any point on Earth to set the impact site, then watch layered destruction rings render at scaled radii in real time.
Live near-Earth asteroid feed — mass, diameter, composition, approach velocity, and impact probability pulled directly from JPL's Center for Near Earth Object Studies.
The same scientific framework as Purdue's "Impact Earth" — models crater radius, fireball zone, thermal radiation radius, seismic effects, and air blast wave from first principles.
Every line of the physics model, API integration, and globe renderer is open source. Fork it, audit it, extend it.
What gets modeled.
Transient and final crater diameter computed from impactor kinetic energy, target density, and impact angle.
Radius within which the fireball causes third-degree burns on exposed skin, scaled to impactor energy and atmospheric entry velocity.
Thermal fluence at distance — ignition of combustibles, second-degree burn threshold, first-degree burn threshold rendered as concentric rings.
Richter-scale equivalent seismic magnitude and overpressure wave — structural damage thresholds mapped to distance from impact point.
What it runs on.
