0:49
A TIE Fighter blows up a huge asteroid. The Millennium Falcon is 34.75m long.
83 pixels = 34.75m
1 pixel = 34.75m/83 = 0.418674699m
0.418674699m X 238 = 99.6445784m
99.6445784m/2 = 49.8222892m
0.418674699m X 170 = 71.1746988m
71.1746988m/2 = 35.5873494m

Volume as an ellipsoid.

V = 4/3πabc
= 4/3 X π X 49.8222892 X 35.5873494 X 35.5873494
= 264303.9m^3

Fragmentation of rock is 8000000 joules.m^3.

E = 264303.9 X 8000000
= 2114431200000 joules
= 505.3611854684513 tons of TNT

Final Results
TIE Fighter destroys asteroid = 505.361 tons of TNT
