TNO/centaur eccentricities vs. semimajor axes and resonance objects

compiled by Wm. Robert Johnston
last updated 14 February 2015

The above graph plots eccentricity versus semimajor axis for outer solar system objects (red points). Orbital resonances with Neptune are also identified (green lines).

The following table lists resonance locations and objects in each resonance as currently identified. Note that while additional objects have semimajor axes near these values, their orbits are less well determined. These are as determined by the Deep Ecliptic Survey supplemented by the Minor Planet Center.
