Calc requested by Js, feat happens in Lesson Zero.
Celestia moves the sun. That's her thing, that's what she does.
I messed up the scaling a bit so the sun is actually only 140 pixels. It starts moving at 3.135.
It reaches a distance of 50 pixels at 4.874
4.874 - 3.135 = 1.739s
The Sun has a diameter of 1,391,400,037.21 meters
140 / 50 = 2.8
1,391,400,037.21 / 2.8 = 496,928,584.718 meters
496,928,584.718 m / 1.739s = 285,755,368 m/s
0.953c
The sun has a mass of 1.989 × 10^30 kg
Relativistic Kinetic Energy time bois
That gives us a value of 4.089E+47 J
4.08 KiloFOE
Since this is over 0.94c, I'm not sure if we can use it, but I'm not sure what the exact logic behind that rule is.
