In the Sun-Mercury closed gravitating system, from the viewpoint
of the Sun, Mercury is oscillating back and forth, and from the
viewpoint of Mercury it's the Sun that's oscillating back and
forth. Beyond that, there is nothing else of any consequence
within that system. Mercury's orbit trajectory is determined
entirely from within that closed system.
Not a closed system. Jupiter perturbes the orbid of Mercury.
The GR correction is on top of all other perturbations. I don't know
anything about elasticity, the simple fact of the matter is that
Mercury is determined by the Scwartzchild metric, that is to say it is
attracted not to the center of the Sun but a point some distance away
- the Schwarzchild radius.
Leverrier took account of Jupiter and all the other planets, but still
the error remained.
