Newtonian Computation of Perihelion Precession of Mercury—An Update

A updated numerical evaluation of the Newtonian component of Mercury’s perihelion advance over more than two centuries starting from about the year 2000 is made using the Euler’s algorithm as well as a modified Euler algorithm. Results are given for about the last 30 years of this interval which show that the precession rate may be substantially higher than what it is believed to be.
