Newsflash: Todd Ingram still doesn't like the moon all that much.
Same thing as before, just doing the same thing using the comic book versions.

Unfortunately for us, the art style used is very cartoon-like, resulting in such oddities as oval-shaped Moons, making a perfect curvature and even the chord method rather imprecise. I'm doing the best I can, here.
Diameter of the Moon: ~3474000 meters
Shot 1:
3474000 m / 542 px = 6409.594 m/px,
x111.61 px = 715374.786 meters
Radius: 357687.393 meters
Depth: 178843.697 meters
Volume: 9.584501e+16 / 2 = 4.792251e+16 cubic meters, or 4.792251e+20 cubic centimeters
Pulverization: x214.35 J/cubic centimeter = 1.02722e+23 Joules, or... only 24.551 Teratons of TNT?
Huh, weird. Let's try the next one?
3474000 m / 71 px = 48929.577 m/px,
x17.26 px = 844524.507 meters
Radius: 422262.254 meters
Depth: 211131.127 meters
Volume: 1.576904e+17 / 2 = 7.884520e+16 cubic meters, or 7.884520e+20 cubic centimeters
Pulverization: 1.69005e+23 Joules, or 40.353 Teratons of TNT...?

So I'm just going to assume I somehow messed up my last attempt at this dramatically, because I'm getting far lower yields than before, despite the diameters being near-identical. Must've been a conversion error or something. Note that none of this has any bearing on the old speed value.
Edit: Oh no, wait, I got what I did last time by cubing it, not squaring it-
Gah. Feeling really stupid about now. Wonder how long that'd take me to catch on my own...
4.792251e+22 cubic centimeters, or 2.4551 Petatons of TNT
7.884520e+22 cubic centimeters, or 4.0353 Petatons of TNT
Re-edit: The speeds derived from the first take on this feat will have to be re-worked, to accomodate for the new crater depth.
211131.127 meters / 0.1 seconds = 2111311.27 meters/second, or Mach 6204.447
Not really that much lower... eh.
Final Yield[]
Todd Hates the Moon But Not Really This Joke Is Old Power: 2.4551 - 4.0353 Petatons of TNT
