Abstract
The planetary instability described by the Nice model proposes a Neptune dynamic that differs in part from the gradual outward migration previously used to explain the structure of the Kuiper belt (see lecture 4). It is therefore necessary to revisit the origin of this structure in the light of the Nice model to verify its validity. It emerges that certain subtle aspects of the distribution of trans-Neptunian objects can only be explained by taking into account a phase of dynamical instability of the giant planets, such as that described by the Nice model.
