List of minor planets: 520001–521000
This is a partial list of minor planets numbered 520001 to 521000. The data mainly comes from NASA/JPL's Small-Body Orbital Elements and the Minor Planet Center (MPC), with possible information from Lowell Observatory when noted.
The page explains the table columns, links to other pages in the series, and provides a summary of named bodies in this number range along with their naming citations.
New names may be added only after official publication; pre-announcements are not allowed by the IAU Working Group for Small Bodies Nomenclature.
When a discovery is confirmed, it receives a permanent number from the MPC, and the discoverers may propose a name following IAU rules. This list covers only those minor planets in this range that have received names and explains the meanings of those names.
Official naming citations are approved and published by the WGSBN. Before May 2021, citations appeared in MPC’s Minor Planet Circulars; more recent citations can be found in the JPL Small-Body Database. The origins of many names were researched by Lutz D. Schmadel for the Dictionary of Minor Planet Names, based on Paul Herget’s The Names of the Minor Planets, and much of this work is in the public domain.
The WGSBN provides the official naming guidelines for non-cometary small bodies.
