As to what I am trying to accomplish: your comments, suggesting you have some theory about how the planets move that somehow scientists have missed, suggests to me some basic misunderstanding about how science or scientific knowledge works, and I'm trying to get at that, to possibly help you see something you are missing.

I don't even know what you are talking about when you say 'theory'. I can't remember ever seeing a model of the planets rotating around the sun presented as a 'theory.' It's just a model to explain what is understood about it, and of course a simplification. Of course scientists understand that the sun is also moving and if you combine that motion with the orbiting of the planets you of course get a spiral.
