List of minor planets: 550001–551000

The following is a partial list of minor planets, running from minor-planet number 550001 through 551000, inclusive. The primary data for this and other partial lists is based on JPL's "Small-Body Orbital Elements"^[1] and data available from the Minor Planet Center.^[2][3] Critical list information is also provided by the MPC,^[2][3] unless otherwise specified from Lowell Observatory.^[4] A detailed description of the table's columns and additional sources are given on the main page including a complete list of every page in this series, and a statistical break-up on the dynamical classification of minor planets.

Also see the summary list of all named bodies in numerical and alphabetical order, and the corresponding naming citations for the number range of this particular list. New namings may only be added to this list after official publication, as the preannouncement of names is condemned by the Working Group for Small Bodies Nomenclature of the International Astronomical Union.

Meaning of names

This is a partial list of meanings of minor-planet names. Also see list of named minor planets (alphabetical) for a condensed version without naming citations.

As minor planet discoveries are confirmed, they are given a permanent number by the IAU's Minor Planet Center (MPC), and the discoverers can then submit names for them, following the IAU's naming conventions. The list below concerns those minor planets in the specified number-range that have received names, and explains the meanings of those names.

Official naming citations of newly named small Solar System bodies are approved and published in a bulletin by IAU's Working Group for Small Bodies Nomenclature (WGSBN).^[5] Before May 2021, citations were published in MPC's Minor Planet Circulars for many decades.^[6] Recent citations can also be found on the JPL Small-Body Database (SBDB).^[7] Until his death in 2016, German astronomer Lutz D. Schmadel compiled these citations into the Dictionary of Minor Planet Names (DMP) and regularly updated the collection.^[8][9]

Based on Paul Herget's The Names of the Minor Planets,^[10] Schmadel also researched the unclear origin of numerous asteroids, most of which had been named prior to World War II. This article incorporates text from this source, which is in the public domain: SBDB New namings may only be added to this list below after official publication as the preannouncement of names is condemned.^[11] The WGSBN publishes a comprehensive guideline for the naming rules of non-cometary small Solar System bodies.^[12]
