Asteroid impact calculator estimates energy release, crater size, and environmental effects based on impact velocity, size, and composition.
ステップバイステップガイド
- 1Input asteroid diameter/mass and impact velocity
- 2Calculate kinetic energy and TNT equivalent
- 3Estimate crater size and damage radius
解いた例
入力
10 km asteroid, 20 km/s impact velocity
結果
10¹⁸ J energy (100 million megatons TNT), extinction-level event
65 Mya extinction
避けるべきよくある間違い
- ✕Neglecting gravity assist effects
- ✕Assuming all velocity energy transfers to crater
よくある質問
How do you calculate impact energy?
KE = 0.5 × m × v²; smaller changes in v have dramatic effects.
