Meanings of minor planet names: 50001–51000

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.

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.

Official naming citations of newly named small Solar System bodies are published in MPC's Minor Planet Circulars several times a year.[1] Recent citations can also be found on the JPL Small-Body Database (SBDB).[2] 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.[3][4] Based on Paul Herget's The Names of the Minor Planets,[5] Schmadel also researched the unclear origin of numerous asteroids, most of which had been named prior to World War II.  This article incorporates public domain material from the United States Government document: "SBDB". New namings may only be added after official publication as the preannouncement of names is condemned by the Committee on Small Body Nomenclature.[6]
