According to the Newton's Mechanics, always:

As it is known, the astronomic observations on the advance of the perihelion of planet Mercury produce a value of D = 574"./century.

According to the study of L. Verierr (1835), the sum of the perturbative forces of all other planets (Venus, Earth, Mars….. Pluto) on planet Mercury produce a value of D' = 531"./century.

Thus, there is a difference of:

δ = D - D' = 574''/century - 531''/century = 43''/century.

L. Verierr, in his study, considered that the center of mass of the Sun and the center of mass of the Solar System coincide (namely they are in the same position).

But this is wrong because these two mass canters do not coincide, see:

Also, as it is known, the Sun and the planets rotate around the center of mass of our solar system and not around the center of mass of the Sun .

Consequently, if, in our calculations, we take into account the Sun's and the planets' rotation around the center of mass of the Solar System and not around the center of mass of the Sun (as it has been happening until today) then we once again have the same difference:

δ = D - D' = 574.''/century - 531''/century = 43''/century

as it is claimed by L. Verierr in his study?

This was my question.

Also,As appears on:

http://astro.berkeley.edu/~eliot/Astro7A/Gravity.pdfpict.3

The average distance (radius) R of the Sun's rotation around the center of mass of the solar system is:

R = 2.4 Rs

Where Rs is the radius of the Sun.

Consequently, the center of mass of the Solar system is located outside of the mass of the Sun!!!

Following the above, I would like to ask from the physicists of this forum to let me know the relevant bibliography where it is mentioned whether, from the age of Le Verrier (1835) to nowadays (2007), it has been taken into consideration the rotation of the Sun around the center of mass of the solar system for the calculation of the perihelion advance δ = 43"/century of planet Mercury.
