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)
  • Size
  • Density of Projectile (average density of the meteor is 3500 kg/m^3)
  • Density of Target
  • Location of Impact
  • TimeFrame

Optional (though not necessary)

  • Trajectory
  • Distance

You can use the following for reference or calculator simplification.

Or just go with the simple equation of:

  • KE=0.5*Mass*Speed^2
