Comment on "New General Relativistic Contribution to Mercury's Perihelion Advance"

TL;DR

This paper critiques and refines a recent prediction of Mercury's perihelion precession, providing a more accurate estimate that significantly differs from the original claim.

Contribution

It offers a revised calculation of Mercury's precession rate, challenging the magnitude of the recently proposed relativistic contribution.

Findings

Revised Mercury precession rate is approximately 6.4×10⁻⁸ degrees per century.

The new estimate is about 30 times larger than the second-post-Newtonian contribution.

The calculated precession rate differs notably from the recent prediction by C. M. Will.

Abstract

C. M. Will in a recent Letter [arXiv:1802.05304] predicts a new Mercury's precession rate which is $100$ times larger than the second-post-Newtonian contribution, our calculation is about $30$ times larger. Thus the new Mercury's precession rate is about $6.4\ast 10^{-8}$, instead of $6.2\ast 10^{-8}$, degrees per century.
