planets

Minimal implementation for planetary system (n-body problem) with pygame and numpy. It prints the FPS and the sum of mass*velocity once per second in your terminal. To stop drifting of the planets, an additional planet is added with a velocity vector which is the opposite of the sum of all (randomly generated) planets' velocity vectors.

For more details, see my blog post.

Setup
