The theory of gravitational anti-screening, which has previously been applied to various astronomical observations as an alternative to dark matter, is now applied to the solar system. The effect that gravitational anti-screening has on the precession rate of the planets will be determined and compared to current observations. In addition, the effect that gravitational anti-screening will have on certain orbital parameters of long-period comets will be determined. The set of 119 long-period comets that are considered in this paper have a broad peak of aphelion distances, based on current gravitational theory, centred at approximately 50 kAU. In the case of gravitational anti-screening, these aphelion distances will be shown to be greatly reduced to a narrow distribution centred at approximately 10 kAU. It is further found from the theory that comets orbiting at this distance will have orbital speeds approximately 20% greater than that predicted from Newtonian gravitational theory.

太阳系内的引力反屏蔽和预测

引力反屏蔽理论以前曾被应用于各种天文观测，作为暗物质的替代品，现在被应用于太阳系。引力反屏蔽对行星进动率的影响将被确定并与当前的观测结果进行比较。此外，还将确定引力反屏蔽对长周期彗星某些轨道参数的影响。根据当前的引力理论，本文考虑的 119 颗长周期彗星的远日点距离峰值很宽，中心约为 50 kAU。在引力反屏蔽的情况下，这些远日点距离将被证明大大减少到以大约 10 kAU 为中心的狭窄分布。
