Image: KBOs and resonances

Description: Distribution of Kuiper belt objects' orbits. Objects in resonance are plotted in red (Neptune trojans 1:1, plutinos 2:3, twotinos 1:2,…). Classical objects are plotted in blue. Scattered disk objects (not members of the Kuiper Belt) are shown in grey, Sednoids in yellow. Generated by Renerpho. Main graph The position of an object represents its orbit’s semi-major axis a in AU and orbital period P in years (horizontal axis, logarithmic scale) 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 diameter corresponding to the absolute magnitude and an albedo of 0.09 (mean value for medium sized KBOs). Main resonances with Neptune are marked with vertical red bars; 1:1 marks the position of Neptune’s orbit (and its Trojan asteroids), 2:3 marks the orbit of Pluto (and the other Plutinos) etc. Data source JPL Small-Body Database as of 2016-09-04. Resonant orbits' classification and diameter estimates from [1] (2016-05-01).
