How to Calculate Asteroid Impact

What is Asteroid Impact?

Asteroid impact calculator estimates energy release, crater size, and environmental effects based on impact velocity, size, and composition.

Step-by-Step Guide

  1. 1Input asteroid diameter/mass and impact velocity
  2. 2Calculate kinetic energy and TNT equivalent
  3. 3Estimate crater size and damage radius

Worked Examples

Input
10 km asteroid, 20 km/s impact velocity
Result
10¹⁸ J energy (100 million megatons TNT), extinction-level event
65 Mya extinction

Common Mistakes to Avoid

  • Neglecting gravity assist effects
  • Assuming all velocity energy transfers to crater

Frequently Asked Questions

How do you calculate impact energy?

KE = 0.5 × m × v²; smaller changes in v have dramatic effects.
