标题： A candidate location for Planet Nine from an interstellar meteoroid: The messenger hypothesis

摘要： 假设太阳系外部存在一颗假想中的第九行星已被提出作为一种可能的解释，用于解释跨海王星天体轨道中出现的异常聚集现象。 我们在此提出，一些到达地球的流星可能充当信使，有可能揭示出一个迄今为止未被发现的大量物体的存在。 最近提出的作为第一个星际流星的奇特流星CNEOS 2014-01-08可能是这样一个信使。 该流星的辐射点位于之前研究中计算出的第九行星位置的最大概率区域内。 这种巧合由偶然性导致的概率约为1\%。 关于CNEOS 2014-01-08的异常现象，在假设它是由引力相遇被抛向地球的情况下可以得到解决。 将其轨迹逆向推算，则会指向第九行星更可能存在的天空区域。 根据现有数据，我们提议坐标R.A. 53.0 +/- 4.3 度，赤纬 9.2 +/- 1.3 度的区域作为第九行星的一个合理候选位置。 显示英文摘要

摘要： The existence of a hypothetical Planet 9 lurkng in the outer solar system has been invoked as a plausible explanation for the anomalous clustering in the orbits of trans-Neptunian objects. Here we propose that some meteoroids arriving at Earth could serve as messengers with the potential of revealing the presence of a hitherto undiscovered massive object. The peculiar meteor CNEOS 2014-01-08, recently put forward as the first interstellar meteor, might be one such messenger. The meteor radiant is in the maximum probability region calculated for the Planet 9 location in previous works. The odds of this coincidence being due to chance are ~1%. Furthermore, some statistical anomalies about CNEOS 2014-01-08 are resolved under the hypothesis that it was flung at Earth by a gravitational encounter. Integrating its trajectory backwards in time would then lead to the region of the sky where Planet 9 is more likely to reside. Based on the available data, we propose the region at coordinates R.A. 53.0 +/- 4.3 deg, declination 9.2 +/- 1.3 deg as a plausible candidate location for Planet 9.
