Refer to this question: How would the rotational and orbital mechanics differ on a torus-shaped planet as compared to a spherical planet?
This is asking about torus-shaped planet rotational and orbital mechanics.
To me this is a question can be answered completely using Newtonian physics, and is as mainstream as the mechanics of spherical planet, however it was closed because "we deal with mainstream physics here", implying that somehow, Newtonian physics doesn't apply to torus shaped planet.
I don't see the logic of the closure. Care to explain?
