Default The Motion of the Perihelion of Mercury

THE MOTION OF THE PERIHELION OF MERCURY


No need to repeat the title twice, we can read.

In his general relativity calculation of the motion of the perihelion
of Mercury Albert Einstein had only taken into account the
gravitational actions between the Sun and the Mercury, which he also
assumed as two points.


Entirely correct.


What will be, according to the theory of general relativity, the value
of the motion of the perihelion of Mercury if the gravitational
actions of all the planets in the solar system are taken into account
and also it is taken into account that the Sun is a little oblate?


Unknown to me, but I haven't done a literature search.

The classical analysis for Mercury's perihelion precession is almost
completely explained using perturbation theory, from the effects of
other planets. There is no reason - except for it being hard - that
the analysis can't be replicated while taking into account effects
from the other planets.

However, the effect between the Sun and Mercury is sufficient to
explain what is observed. There's a breakdown in MTW, by the way.


Have any done these calculations?
