Glossary term: Ceinture de Kuiper
Description: La ceinture de Kuiper est une bande de petits objets glacés situés dans le Système solaire externe, principalement au-delà de l'orbite de Neptune. La plupart des objets se trouvent à des distances de 40 à 48 unités astronomiques du Soleil.
Les objets de la ceinture de Kuiper sont pour la plupart de petite taille, bien que l'on y trouve plusieurs planètes naines, dont Pluton. Contrairement aux petits corps et aux planètes naines de la ceinture d'astéroïdes, les objets de la ceinture de Kuiper sont principalement constitués d'eau gelée, de méthane et d'ammoniac.
