 Unnumbered TNOs 

There are more than 3,000 unnumbered trans-Neptunian objects, defined here as minor planets with a semi-major axis larger than 30.1 AU (Neptune's average orbital distance from the Sun). The data is sourced from MPC's "List of Trans Neptunian Objects" and "List Of Centaurs and Scattered-Disk Objects", completed with information from Johnston's Archive (diameter, class, binary status, etc.). For the list of numbered TNOs, see .

 Trans-Neptunian satellites 

A growing number of TNOs are revealed to be binary systems with a minor-planet moon orbiting its primary. There are also several multiple systems with more than one satellite.

 Diagram: orbital classes 

Trans-Neptunian objects colorized by their orbital subclass and plotted in the orbital parameter space (eccentricity and inclination versus semi-major axis). The plot for the entire region contains 1418 objects including plutinos (#185), twotinos (#36), other resonant objects (#124), cubewanos (#420), inner (#40) and outer classical objects (#6), SDOs (#289), sednoids (#11), centaurs (#101) and other TNOs (#206).
