Premise[]
Not the entire moon. I'm told this is roughly the size of the moon and that's a pretty neat wound it's got there.
Requested by Skeletor. No idea on context or what it scales to.
Calc[]
Judging by the later images, it is at least as deep as it is wide- so we'll treat it as a half-ellipsoid with those dimensions
Diameter of Planet = 248 px = 3474 km
Diameter of Hole = 10 px = 140.08 km
Remember to halve for all radii except for the depth one.
Volume = 2.88e15 m^3
We'll assume most of this mass is titanium (relatively strong building material) and apply 50% hollowness since this seems to be machinery. I was told this is most likely melting. So 1.44e15 m^3.
Density of Titanium = 4506 kg/m^3
Mass = 6.489e18 kg
Melting Point = 1668 C
Average Temperature = 15 C
Ergo, change in temp is 1653 C. Specific heat of solid titanium is 523 J/(kg*K).
Specific Heat = 5.610e24 Joules
Now for fusion.
Latent Heat of Fusion (Titanium) = 390666 J/kg
Energy = 2.535e24 Joules
Total Energy = 8.145e24 Joules, Continent level. Nais.
