[edit] Summary in English

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

Trans-Neptunian Objects (High Res)

See also the high resolution (richer content) version.

[edit] Main graph

The characteristics of an object in the graph represent:

Distance along horizontal axis
- the object's orbital semi-major axis a in Astronomical Units
- orbital period in years (in red)
Distance along vertical axis - the object's orbital inclination i in degrees
Size of the circle - 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 H of the object.
vertical bars mark orbital resonances with Neptune; 1:1 marks the position of Neptune’s orbit (and its Trojan asteroids), 2:3 marks the orbit of Pluto and plutinos.

[edit] Families

Cubewanos

Centaurs (not formally members of Trans-Neptunian objects, shown for reference only)

Resonant objects - Plutinos and Resonant trans-Neptunian objects

Scattered disc objects

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

[edit] Data source

Minor Planet Center Orbit database (MPCORB) as of 2008-10-05. Resonant orbits' classification from MPEC Circular 2008-S05 (2008-10-01). Diameter estimates include Stansberry et al (Spitzer). See refs in the related articles.

[edit] Description en français

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

[edit] 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.

[edit] 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.

[edit] Source des données

Base de données MPCORB au 1er decembre 2007, sauf pour la classification des orbites résonantes où le Minor Planet Circular 2007-W54 [1] a été utilisé.
