This is so cool! Purdue University sponsors this free, web-based computer program that lets you calculate the damage an asteroid would cause if it collided with Earth. You can customize the size, density, and speed of the incoming object, determine where it will land, and watch an animation of the asteroid’s crash course with our planet. Then find out  the catastrophic results of your efforts (if any).

When you get to the site, wait for the program to load. While you’re waiting, use the menu to learn about “Famous Craters,” read documentation about this project, and check out a short glossary of terms used in the program. Then, simply enter the parameters including: 

  • Projectile Diameter
  • Projectile Density
  • Angle of Impact
  • Velocity
  • Target (Water, Sedimentary Rock, or Crystalline Rock)
  • Distance from Impact

Finally, click on “Calculate Impact” to start the animation and see the results. If you’re not sure what to input, there are drop-down lists with suggestions you can use. Once you get the hang of it, it’s fascinating to try different scenarios to see if humanity survives your asteroid or suffers total annihilation.
