List of unnumbered trans-Neptunian objects

	TNOs: a vs. e (semi-log plot, 30–1000 AU):
	Resonant plutinos (39 AU) and twotinos (48 AU) Inner and outer classical objects (< 39 and > 49 AU) Other resonant objects besides plutinos and twotinos Classical Kuiper belt objects (cubewanos) Scattered disc objects (SDO) Other TNOs (dots) and centaurs (asterisk) Sednoids, prominent ETNOs
	Distribution of 3,590 listed TNO objects (with a > 30.1 AU, including candidates) by subclass from Johnston's Archive (hover)

This is a list of unnumbered trans-Neptunian objects (TNOs) first observed since 1993 and grouped by the year of principal provisional designation. The data is sourced from the Minor Planet Center's (MPC) List of Trans Neptunian Objects and List Of Centaurs and Scattered-Disk Objects.^[2]^[3] These objects will eventually be numbered as secured discoveries with an official discoverer determined by the MPC. Until then, additional observations are needed to sufficiently decrease an object's orbital uncertainty. As of April 2022, there are 3,141 unnumbered objects, defined here as minor planets with a semi-major axis larger than 30.1 AU (Neptune's average orbital distance from the Sun).^{[lower-alpha 1]}

The list also contains information from "Johnston's Archive", such as an object's diameter, its dynamical class and binary status with the satellite's diameter, as well as its albedo, spectral taxonomy and B–R color index.^[1] Members of the extreme trans-Neptunian objects (ESDOs, EDDOs and sednoids) – with a semi-major axis greater than 150 AU and perihelion greater than 30 AU – are also identified.

Notes

1 2 According to Johnston's Archive,^{[lower-alpha 2]} there are 50+ objects with a semi-major axis larger than 30.1 AU that are excluded from the two MPC sources. These ignored objects are the damocloids and the Neptune trojans, as well as three unusual objects 2003 UY₂₈₃ (MPC/JPL), 2004 CM₁₁₁ (MPC/JPL) and 2015 RL₂₇₇ (MPC/JPL).
