Studied your post GSS.
Certainly there are convenient astronomical CS's like the
Copernicus solar centered, but there is no *physical*
reason to adopt that as an origin, ie. the measurements
aren't more accurate than using any other CS.
I doubt you understand yet the meaning of relativity if you
advance such notions.
