Résumé
Abstract

Dix ans après la découverte du premier objet orbitant au-delà de Neptune, le nombre d'objets de la ceinture de Edgeworth-Kuiper détectés avoisine 800 : après la découverte de 1 Ceres, il a fallu en revanche attendre 115 ans pour découvrir un nombre équivalent d'astéroı̈des de la ceinture principale. Ces grandes comètes à l'apparence d'astéroı̈des sont des objets dont la faible luminosité est un défi pour les observateurs. Ce groupe représente – comme les comètes et les astéroı̈des – une source d'information précieuse sur l'environnement physique et chimique du système solaire au moment de la formation des planètes. Dans cet article, nous récapitulons les résultats des premières analyses statistiques des propriétés physiques et chimiques des objets de la ceinture de Kuiper basées sur des données de photométrie à large bande.

Ten years after the discovery of the first object entirely outside the orbit of Neptune, the number of detected Edgeworth-Kuiper Belt objects (EKBO) is close to 800: after the discovery of the asteroid 1 Ceres, it took 115 years to discover the same number of asteroids. These large comets dressed as asteroids are very elusive objects, challenging the observers with their faintness. As well as the comets and the asteroids, this group of objects represent a valuable source of information on the physical and chemical environment of the Solar System at the epoch of planet growth. In this paper we summarize the results of the first statistical studies of the bulk physical and chemical properties of EKBO, based on broad band photometry data.
