Free-Fall orbits are gravitational orbits where all planets start at rest and oscillate along open curves

Now plot the same orbits in a coordinate system in which one of the planets is at rest. Betcha the others will just be moving on regular closed curves...

Why don’t you do it

I get that it’s mathematically possible, but not something we’d see in the real world. However, the fact that the planets are on open curves is driving me up the wall! How am I supposed to sleep at night knowing math simulations allow this kind of stuff to happen?!

There’s no issue with this. The reason you don’t see it isn’t because it’s impossible it’s that (1) it’s unlikely and (2) unstable

Will they relax into circular orbits if perturbed by outside forces?

No - a slight perturbation makes it chaotichttps://twitter.com/KangarooPhysics/status/1204916263660793856 …

Never thought about this before, so cool. My mathematical knowledge is in the stone age compared to this kind of thinking
