Abstract

We analyze the minimum orbital intersection distances (MOIDs) for a sample of long-period comets (1360) and the giant planets of the Solar System. Our calculations have revealed a considerable number of long-period comets that may have had close encounters with the giant planets: Jupiter (268), Saturn (176), Uranus (81), and Neptune (75). Among them there are 107 cases where the comet approaches two or more planets. Besides, we have also performed an analysis of the cometary orbits based on Tisserand’s criterion, which showed that more than 10\(\%\) of the comets from the group of Jupiter have \(2<T<3\). There are such values in slightly smaller quantities in the groups of other planets as well. We have also tested our statistical results and conclusions.

关于巨型行星长周期彗星族的存在

摘要

我们分析了一个长周期彗星（1360）和太阳系巨大行星的样本的最小轨道相交距离（MOID）。我们的计算结果表明，可能有大量的与彗星紧密相遇的长周期彗星：木星（268），土星（176），天王星（81）和海王星（75）。其中有107颗彗星接近两个或更多行星的情况。此外，我们还根据蒂瑟兰德准则对彗星轨道进行了分析，结果表明，来自木星群的彗星中有10个以上\（\％\）具有\（2 <T <3 \）。在其他行星的组中也存在少量这样的值。我们还测试了我们的统计结果和结论。
