    $\begingroup$ @uhoh You should check out Cris Moore's insane braided orbits. See tuvalu.santafe.edu/~moore/gallery.html for links to animated diagrams and papers. Of course, these orbits are extremely unlikely to occur naturally. They're reasonably stable to small perturbations of position and velocity, but not to variations in the masses, which need to be almost identical. $\endgroup$
