Definition

The Kuiper Belt is the region in the solar system beyond the orbit of Neptune that contains icy bodies orbiting the Sun.

Overview

In the last decades, the outer solar system has been found to be densely populated by a multitude of icy bodies called Kuiper Belt objects, Edgeworth–Kuiper objects, or Trans-Neptunian Objects. The discovery of these bodies revolutionized our understanding of the solar system and most ideas relative to the evolution of the protoplanetary nebula. The general interest in the outer solar system grew rapidly in the scientific community. In fact, these bodies located so far from the Sun are considered as the fossils of the protoplanetary disk, which, consequently, can provide important information on the processes that dominated the evolution of the early solar nebula as well as of other planetary systems around young stars.
