You can use Fragmentation or Pulverization
If you using Earth volume ( in cc) × Fragmentation or Pulverization energy (j/cc)
Edit : or just Using GBE then

i heard there's more to it

Using GBE then, U = 3GM^2/5r
G = Gravitational Constant
M= mass of the Planet
r = Radius of the planet

aight, but i'll wait for more opinions as i want it to be very accurate

If you want to be more and more accurate You can should find the Size of that planet rather than assuming the size.

Assume the size of the earth (this is the standard), and use the gravitational binding energy, which is going to be baseline planet level. Hope I helped.

no rings have nothing to do with size. If the moon was busted to rubble, then it would give the earth a ring, as well as kill us all.

I mean we have a visible explosion, wouldn't i be able to calc the explosion?

You should be able to calc KE of fragments

I don't see why you would calculate it with the explosion, as far as I know. The way of calculating a planet busting is gravitational binding energy. You can use kinetic energy for the planet chunks but here you don't know the mass or velocity.

Well RIP

Maybe if it was animated you could do kinetic energy.

There are two options:
- This feat ends up as 5-B because we use Earth as the standard and Earth's GBE is baseline 5-B
- Try getting the KE of the fragments

Using the second method and this image for pixel scaling, here we go. Bear with me, I had to get a rough idea of the planet diameter based on the fragments.
Planet Diameter = 12742000 meters = 433 px
12742000 / 433 = 29427.25 meters per px
Distance Traveled = 364.8 px = 10735060.8 meters
This took 1 panel, so I'll use 5 seconds for the timeframe.
Speed = 10735060.8 / 5 = 2147012.16 m/s
Planet Mass = 5.972e+24 kg
KE = 0.5 * 5.972e+24 * 2147012.16^2 = 1.37644484e+37 Joules or 3.29 ninatons; Large Planet level (5-A)

Wank.

I'm just doing how you would normally calc feats involving debris flying.

If it's accepted as it is now, then yes.

Sure, I'll copy it into a blog soon.

No problem

Yeah I am just joking. I just find it a little dumb that vaporizing a llanet is weaker than breaking a planet into chunks and then moving those chunks quickly.
