The Kuiper Belt and Other Debris Disks

TL;DR

This paper reviews the Kuiper belt and debris disks, highlighting their significance in understanding Solar system formation and their relationship with similar structures around other stars.

Contribution

It synthesizes current knowledge of the Kuiper belt and debris disks, emphasizing their roles in Solar system history and comparative planetary science.

Findings

Kuiper belt is a collisional dust source.

Debris disks around stars are analogous to our Kuiper belt.

Studying the Solar system helps interpret distant debris disks.

Abstract

We discuss the current knowledge of the Solar system, focusing on bodies in the outer regions, on the information they provide concerning Solar system formation, and on the possible relationships that may exist between our system and the debris disks of other stars. Beyond the domains of the Terrestrial and giant planets, the comets in the Kuiper belt and the Oort cloud preserve some of our most pristine materials. The Kuiper belt, in particular, is a collisional dust source and a scientific bridge to the dusty "debris disks" observed around many nearby main-sequence stars. Study of the Solar system provides a level of detail that we cannot discern in the distant disks while observations of the disks may help to set the Solar system in proper context.
