By just playing around with Planetary systems that have more than 2 bodies (they can be utterly Complex and it is almost impossible to find a stable Constellation), you can easily see why such Solutions are so stunning. Being surprisingly simple as merely taking the form an Eight, makes this one stand out a lot for me.
Thanks. The Wikipedia article has had this animation forever, but I haven’t noticed that they also specify the initial conditions and a reference to this same paper. I built an “orbital playground” in Processing some time ago and was trying to guess values which would do something like the figure eight thing.
Consider making your git repo a valid sketch by moving the pde files into a correctly named subdirectory. The sketch folder and the entrypoint PDE names must match exactly.
