论文摘要
Kuiper带对象，或更一般的跨核对象（TNOS）是海王星轨道以外的行星。一些TNO演变成海王星交叉轨道，并成为半人马场。反过来，许多半人马到达了木星 - 横断轨道，并成为木星家族彗星（JFCS）。 TNO是JFC的主要来源。 TNO提供的窗口与JFC的窗口不同，具有更原始的身体以及不同的尺寸和温度范围。正是在这种情况下，本章写了。在这里，我们讨论了从跨北河区到JFC的动态途径，以及与JFC人群相关的TNO的最重要特性，包括考虑其起源，组成，形态和大小分布的考虑。我们尽可能将这些属性与JFC相关联。我们反思一些有关我们对TNO的不完整知识的关键问题，因为它们与CentAurs和JFC人群有关。我们将简短的讨论讨论了著名的新设施，以及他们将对这些杰出问题产生的影响。
Kuiper Belt Objects, or more generally Trans-Neptunian Objects (TNOs), are planetesimals found beyond the orbit of Neptune. Some TNOs evolve onto Neptune-crossing orbits and become Centaurs. Many Centaurs, in turn, reach Jupiter-crossing orbits and become Jupiter-family comets (JFCs). TNOs are the main source of the JFCs. TNOs offer a different window than the JFCs, of more primordial bodies and over a different size and temperature range. It is in that context that this chapter is written. Here we discuss the dynamical pathways taken from the trans-Neptunian region to the JFCs, and the most important properties of TNOs that relate to the JFC population, including considerations of their origins, compositions, morphologies, and size distributions. We relate these properties to the JFCs whenever possible. We reflect on a few key outstanding issues regarding our incomplete knowledge of TNOs as they pertain to the Centaurs and JFC populations. We finish with a short discussion of notable new and upcoming facilities and the impacts they will have regarding these outstanding questions.
