[edit] Summary
(voir plus loin pour la description en français)
Distribution of orbits for Centaurs (in polar coordinate system).
The position of an object represents
- its orbit’s semi-major axis a in AU and orbital period ini years (horizontal axis)
- orbit’s inclination i in degrees (vertical axis).
The size of the circle illustrates the object’s size relative to others. For a few large objects, the diameter drawn represents the best current estimates. For all others, the circles represent the absolute magnitude of the object. The eccentricity of the orbit is shown indirectly by a segment extending from the left (perihelion) to the aphelion to the right. In other words, the segment illustrates the variations of the object's distance from the Sun. Objects with nearly circular orbits will show short segments while highly elliptical orbits will be represented by long segments.
The orbits of planets Saturn, Uranus and Neptune are marked with grey arcs.

[edit] Description en français
Distribution des centaures.
La position d’un objet représente
- le demi axe majeur (rayon moyen) de son orbite a en in au (l’axe horizontal)
- l’inclination de son orbite i en degrés.
Le diamètre du cercle montre la taille relative de l’objet aux autres. Pour quelques grands objets, le diamètre représente la meilleure estimation connue. Pour tous les autre, le diamètre du cercle représente la magnitude absolue de l’objet. L’excentricité de l’orbite est représentée indirectement par un segment qui s’étend du périhélie à gauche à l’aphélie à droite. En d’autres termes, le segment illustre les variations de la distance du Soleil. Les objets avec des orbites quasi circulaires ont donc des courts segments et les orbites très excentriques sont repérées par des segments longs.
Les orbites de Jupiter, Saturne et Uranus sont marquées.
