Explaining the reason for the slight deviation of Mercury's planet from its orbit based on the theory of motion gravity

If we look at modified Newton's general gravitational equations based on the theory of kinetic gravity, we will see that based on the theory of kinetic gravity, the solar system moves through the Milky Way and space, including the Sun and planet Mercury. As a result, in this situation we will see the phenomenon of gravitational equilibrium change and the effect of the gravity of the sun on the planet Mercury when the planet Mercury orbits in the orbit of the sun, in the direction of the sun's orbit in space, or At a certain angle to the direction of the sun's motion in space, it changes, and the table The influence of the gravity of the sun on that orbital range on orbit of Mercury increases or decreases because of the different positions and trajectories of Mercury's orbital motion, two equations have to be used, of course, to calculate the amount of force the sun has on the planet Mercury. The various effects in this theorem become a little complicated, but it is worth noting that the symmetric orbital structure of Mercury's orbital motion around the sun produces a slight deviation and this symmetric orbital motion becomes asymmetric orbital motion
