List of TNO Objects

Trans-Neptunian objects
The below list includes all numbered minor planets that orbit the Sun at a greater distance on average than Neptune—that is, objects with a semi-major axis greater than 30.103 AU—as of 4 December 2012. It also includes several notable unnumbered TNOs; several hundred other unnumbered TNOs are known to exist but are excluded from this list. For moons of trans-Neptunian objects, see the next section.

This list consists of Kuiper belt objects, scattered disc objects and detached objects. Objects with trans-Neptunian orbits that have been classified as centaurs rather than "true" TNOs by some astronomers and institutions (notably the Deep Ecliptic Survey) have also been included. This population of objects has unstable orbits in which the closest approach to the Sun (perihelion) is well inside of Neptune's orbit but the farthest point (aphelion) is very distant; they accordingly travel across Neptune's orbit, the Kuiper belt, and sometimes the scattered disc, and are noted here with a location of "transient".
