This is to calculate the meteor impact that is or would have happened to find the stat for DC.
This involved the following factors:
- Speed (over 11 km/s if in space, lower if from the atmosphere of the planet)
- Density of Projectile (average density of the meteor is 3500 kg/m^3)
- Density of Target
- Location of Impact
Optional (though not necessary)
You can use the following for reference or calculator simplification.
Or just go with the simple equation of:
