This is given in the first approximation to a binomial expansion as Eq. (17), which supplements the orbital precession found numerically by Horst Eckardt. The accuracy of the orbit (17) can be increased by adding more terms of the binomial expansion of the relativistic kinetic energy, Eq. (7). Experimentally, it is found that the perihelion advances by 3MG / (alpha c squared) every two pi radians. I accept the experimental claim for the sake of argument, but reject the Einsteinian general relativity. Dr. Horst Eckardt found by computer algebra that the relativistic potential is given by Eq. (20), which reduces in the limit v << c to the inverse square law, Eq. (21).
