To quote wikipedia "It estimated that objects with mass above 5×1020 kg and diameter greater than 800 km (800 km across) would "normally" be in hydrostatic equilibrium"
930 px = 800000 m
800000 m / 930 px = 860.215054 m/px
50 px * 860.215054 m/px = 43010.7527m
43010.7527/2 = 21505.3763m
Time Frame is 5.23 seconds
V = 21505.3763 m / 5.23 sec = 4111.92663m/sec
KE = 1/2 * 5e20 kg * (4111.92663 m/sec)^2 = 4.2269851526258E+27
4.2269851526258E+27/2 = 2.11349258e27 Joeles
Total Force = 0.5051 Exatons (Multi-Continent+)
