Source-derived summary

The following is a partial list of minor planets, running from minor-planet number 400001 through 401000, inclusive. The primary data for this and other partial lists is based on JPL's "Small-Body Orbital Elements" and data available from the Minor Planet Center. Critical list information is also provided by the MPC, unless otherwise specified from Lowell Observatory. 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

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). Before May 2021, citations were published in MPC's Minor Planet Circulars for many decades.

Editorial summary

The public source identifies “List of minor planets: 400001–401000” as wikimedia list article. This brief keeps that definition visible, then builds a research path around List, minor and planets.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—2021—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with List, minor and planets providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “List of minor planets: 400001–401000”, the useful work is to connect “wikimedia list article” to the records capable of establishing context and consequence.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 9, 2026. The linked authority identifier is Q18349114. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2021.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
