Perihelion Shift of Mercury (again) (クリ)

Shift of perihelion is in the direction of Mercury's own revolution, and speed of shift is constant. Like hands of clock. Main reason will be two-body problem.

How is Sun's gravity acting on Mercury calculated ? Will be by Newton's spherical shell theorem. But is this theorem right ? Has anyone raised any objection ?

Gravity of Sun acting on Mercury depends on square of the distance between them. On the other hand, centrifugal force due to orbital motion of Mercury depends on distance between them. Therefore, the size of Mercury and Sun will also play a role. But it is contrary to the spherical shell theorem.

If the above is right, because the two bodies are close, size of Mercury and Sun will increase the magnitude of gravity. And orbital motion of Mercury will be accelerated.
