So...the 8 body problem? https://en.m.wikipedia.org/wiki/Three-body_problem https://en.m.wikipedia.org/wiki/Three-body_problem

  Often called the N body problem, but the issue occurs when N>=3, so calling it "the 3 body problem" usually sufficiently identifies it in the literature. Great question, and I am happy to have my 1 in 10k time today! (Nice being on the informing end for once). https://xkcd.com/1053/ https://xkcd.com/1053/
