结果表明，当人们正确地计算海王星的质量值并根据观测数据适当地调整天王星的轨道时，所谓的“无法解释的天王星运动异常”就消失了。此外，它还表明，在目前已知的太阳系框架内，每一个“海王星测量位置的不规则性”都有一个完整的解释。作为一种确定性的检验，我们整合了一份与天王星观测结果非常吻合的实际行星星历。数据中确实存在一些小的系统误差，但它们非常小；它们很容易用观测本身的一些不确定性来解释。现在已知在太阳系外有一个相当大的质量集中- 1992 QB1。然而，与任何一颗主要行星相比，这个天体都是微不足道的。对于子午线圈的观测，仍然没有证据要求甚至表明存在任何行星大小的物体；仍然没有必要假设太阳系中存在第十颗行星。
It is shown that the alleged 'unexplained anomalies in the motion of Uranus' disappear when one properly accounts for the correct value of the mass of Neptune and properly adjusts the orbit of Uranus to the observational data. Also, it is shown that each of the 'irregularities in the measured positions of Neptune' has a complete explanation within the framework of the presently known solar system. As a check of certainty, an actual planetary ephemeris is integrated which well fits the observations of Uranus. Minor systematic errors do remain in the data, but they are very small; they are easily explained by a number of uncertainties in the observations themselves. There is now known to be a mass concentration of significant size in the outer solar system - 1992 QB1. In comparison to any of the major planets, though, this object is miniscule. For the meridian circle observations, there is still no evidence which requires or even indicates the existence of any planet-sized object; there remains no need to hypothesize the existence of a tenth planet in the solar system.
