我们指出，存在一个新的广义相对论贡献的近日点推进的水星，而小于所产生的贡献从太阳四极矩和角动量，是100倍以上的第二后牛顿贡献。它部分来自后牛顿运动方程中水星与太阳和其他行星相互作用的相对论性“交叉项”，部分来自水星运动和运动行星重力磁场之间的相互作用。在每世纪42.98角秒的主要广义相对论岁差的10^{6}分之几处，这些效应很可能被BepiColombo使命探测到，该使命计划在2018年左右发射，以放置和跟踪水星周围的两个轨道器。
We point out the existence of a new general relativistic contribution to the perihelion advance of Mercury that, while smaller than the contributions arising from the solar quadrupole moment and angular momentum, is 100 times larger than the second-post-Newtonian contribution. It arises in part from relativistic "crossterms" in the post-Newtonian equations of motion between Mercury's interaction with the Sun and with the other planets, and in part from an interaction between Mercury's motion and the gravitomagnetic field of the moving planets. At a few parts in 10^{6} of the leading general relativistic precession of 42.98 arcseconds per century, these effects are likely to be detectable by the BepiColombo mission to place and track two orbiters around Mercury, scheduled for launch around 2018.
