Three bodies problem, Blender Game Engine

I wanted to test the Blender BGE engine to solve simple physics simulation problems. Here I integrate the three bodies problem for masses gravitationally related. The yellow central body has mass m03 and the other two m1, m20. 1 and they interact gravitationally with acceleration AxGm0m1, (r3)x where G10 and r is the distance between bodies. A very cool animated visualization of the movements of the masses is realized easily with Blender. Good for educational purposes, for example.
