Summary

(voir plus loin pour la description en français)

The distribution and classification of the trans-Neptunian Objects. Generated by a program written by Eurocommuter.

Main graph

The position of an object represents

  • its orbit’s semi-major axis a in AU (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 the others, the diameter of the circle represents the absolute magnitude of the object.
  • orbital resonances with Neptune are marked with vertical bars; 1:1 marks the position of Neptune’s orbit (and its Trojan asteroids), 2:3 marks the orbit of Pluto and plutinos.

Families

  • Centaurs are not formally members of Trans-Neptunian objects, shown for reference only
  • Kuiper Belt, includes
    • cubewanos, in blue
    • resonant objects: plutinos and twotinos, in red
  • Scattered Disk objects, in grey

To highlight other resonant objects, all of them are plotted in red.

Data source

MPCORB as of Feb 14th, 2006, except for resonant orbits' classification. Minor Planet Circular 2005-X77 [1] was used instead.

Description en français

La distribution et les familles des transneptuniens Graphique généré par un programme écrit par Eurocommuter.

Graphe principal

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 (axe vertical).

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 autres, le diamètre du cercle représente la magnitude absolue de l’objet.

Les positions des résonances avec Neptune sont marqués par des traits verticaux; 1:1 marque la position de l’orbite de Neptune (et ses Troyens), 2:3 marque l’orbite de Pluton (et ses lunes) etc.

Familles

  • Centaures ne sont pas formellement membres des transneptuniens
  • La Ceinture de Kuiper regroupe
    • Objets classiques, cubewanos, en bleu
    • Objets résonants en 2:3 et 1:2, en rouge
  • Objets épars, en gris

Pour repérage facile tous les autres objets résonants sont en rouge.

Source des donnés

Base de donnés MPCORB au 14 Février, 2006 sauf pour la classification des orbites résonantes où le Minor Planet Circular 2005-X77 [2] a été utilisé.
