这篇文章最初是为了配合我在瑞士和夏威夷大学天文研究所举办的“第35期萨斯-费用高级课程”的一系列讲座而写的。它回顾了我目前对彗星动力学的理解，以及它们的水库的起源和原始雕刻。它开始讨论柯伊伯带的结构和柯伊伯带天体的当前动力学，包括分散的盘状天体。然后讨论了外海王星区木星族彗星和奥尔特云长周期彗星的动力学演化。奥尔特云的形成，然后审查，以及柯伊伯带的原始雕刻。最后，这些问题被重新审视的巨行星演化的一个新的模型，已被开发来解释的起源晚重轰击的类地行星。
This text was originally written to accompany a series of lectures that I gave at the `35th Saas-Fee advanced course' in Switzerland and at the Institute for Astronomy of the University of Hawaii. It reviews my current understanding of the dynamics of comets and of the origin and primordial sculpting of their reservoirs. It starts discussing the structure of the Kuiper belt and the current dynamics of Kuiper belt objects, including scattered disk objects. Then it discusses the dynamical evolution of Jupiter family comets from the trans-Neptunian region, and of long period comets from the Oort cloud. The formation of the Oort cloud is then reviewed, as well as the primordial sculpting of the Kuiper belt. Finally, these issues are revisited in the light of a new model of giant planets evolution that has been developed to explain the origin of the late heavy bombardment of the terrestrial planets.
