Calculation
Picture 1
Diameter of the planet assuming same size as Earth - 117 px or 12,742,000 meters
Picture 2
Distance the rubble was blasted - 438.38 px or 47,742,204.79 meters
Since the explosion was omnidirectional I need to use the radius.
Radius of the explosion - 23,871,102.39 meters
Timeframe - 10:37 - 10:39 or 2 seconds
Speed - 11935551.195 m/s
Mass of the Earth - 5.972e+24 kg
Relativistic Kinetic Energy = 4.259e+38 Joules or 101.79 Ninatons (Dwarf Star level)
Scales to Ultimate Humungousaur, UA Vilgax, and Anodite Form Gwen which is awesome.
Final Tally
Ascalon destroys a planet - 101.79 Ninatons (Dwarf Star level)
