论文摘要
假设行星9在外部太阳系中的存在已被调用，以作为对跨纽布对物体轨道中异常聚类的合理解释。在这里，我们建议一些到达地球的流星物可以作为使者，具有揭示迄今为止未发现的大型物体的存在的潜力。最近作为第一个星际流星提出的奇特的流星木炭2014-01-08可能就是这样的使者。流星辐射位于先前工作中Planet 9位置计算的最大概率区域。偶然造成的巧合的几率约为1％。此外，根据引力遭遇在地球上抛弃它的假设，有关炭干2014-01-08的一些统计异常。然后，及时将其轨迹倒退将导致行星9更可能居住的天空区域。根据可用数据，我们提出了坐标R.A.的区域。 53.0 +/- 4.3度，偏转9.2 +/- 1.3度，作为行星9的合理候选位置。
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.
