# List of minor planets: 10001–11000

This range of the minor-planet catalog covers the 1,000 consecutively numbered minor planets from 10001 to 11000, small solar-system bodies (overwhelmingly asteroids) that have received permanent numbers from the [Minor Planet Center](https://www.edgepedia.org/minor-planet-center) (MPC). Each entry is identified by its number in parentheses followed by its provisional designation, in the form (10001) 1969 TC1 style used throughout the numbered catalog.

| Key fact | Detail |
|---|---|
| Catalog range | Minor planet numbers 10001 through 11000, a block of 1,000 consecutive permanent numbers in the MPC numbered catalog<sup>[1](https://docs.minorplanetcenter.net/mpc-ops-docs/data-and-services/schema/numbered-identifications/)</sup> |
| Packed designation form | In MPC observation records, six-digit numbers are stored in packed form, with `A0000` equal to 100000, so numbers in this range appear as packed five-character codes<sup>[2](https://docs.minorplanetcenter.net/mpc-ops-docs/observations/mpc1992-format/)</sup> |
| Numbering authority | The MPC maintains the numbered identifications table, which contains all numbered objects with their primary provisional designations and is continuously updated<sup>[1](https://docs.minorplanetcenter.net/mpc-ops-docs/data-and-services/schema/numbered-identifications/)</sup> |
| Naming authority | The IAU Working Group on Small Body Nomenclature (WGSBN), a working group with 15 members, 11 of them voting, assigns names to minor planets<sup>[3](https://www.wgsbn-iau.org/)</sup> |
| Naming privilege | The discoverer may propose a name for ten years following the numbering of the object<sup>[4](https://iauarchive.eso.org/public/themes/naming/)</sup> |
| Data access | The JPL Small-Body Database Lookup accepts an IAU number such as a number in this range and returns orbital elements, physical parameters, and discovery circumstances where available<sup>[5](https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html)</sup> |

## Numbering and designation

[A minor](https://www.edgepedia.org/a-minor) planet enters this range only after the MPC assigns it a permanent number, which links the object to its primary provisional designation, the year-and-letter code it carried at discovery. The numbered identifications table records this pairing for every numbered object, together with references to the MPC publications in which the numbering appeared<sup>[1](https://docs.minorplanetcenter.net/mpc-ops-docs/data-and-services/schema/numbered-identifications/)</sup>. Because numbers above 99999 require six digits, the MPC's fixed-format observation records store them in a packed alphanumeric form rather than as plain numerals; the format documentation defines `A0000` as the packed representation of 100000, and numbers in the 10001–11000 range follow the same packed convention<sup>[2](https://docs.minorplanetcenter.net/mpc-ops-docs/observations/mpc1992-format/)</sup>.

## Naming

Numbering and naming are separate steps run by separate bodies. Once an object is numbered, its discoverer is invited to propose a name, a privilege that lasts ten years from numbering<sup>[4](https://iauarchive.eso.org/public/themes/naming/)</sup>. The fifteen-person WGSBN judges all proposals against published guidelines: names should be 16 characters or less, preferably one word, pronounceable in some language, and not too similar to existing minor-planet or satellite names; names of people or events known mainly for political or military activities are unsuitable until 100 years after the death or event, purely commercial names are not allowed, and pet-animal names are discouraged<sup>[4](https://iauarchive.eso.org/public/themes/naming/)</sup>. The WGSBN publishes approved names and citations in the WGSBN Bulletin, issued in numbered batches; recent issues have added names for 8 to 65 minor planets at a time<sup>[3](https://www.wgsbn-iau.org/)</sup>. Across the whole catalog, 26566 minor planets currently carry names<sup>[3](https://www.wgsbn-iau.org/)</sup>, so most objects in the 10001–11000 range are identified by number and provisional designation alone.

## Where the data lives

For any object in this range, two complementary services provide the record. The MPC side holds the numbering and identification history<sup>[1](https://docs.minorplanetcenter.net/mpc-ops-docs/data-and-services/schema/numbered-identifications/)</sup>. The [JPL Small-Body Database](https://www.edgepedia.org/jpl-small-body-database) (SBDB) holds orbital and selected physical data for all known asteroids and comets, computed by JPL's Solar System Dynamics group from MPC observations including radar astrometry where available; its lookup tool accepts the IAU number directly<sup>[5](https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html)</sup><sup> • </sup><sup>[6](https://ssd-api.jpl.nasa.gov/doc/sbdb.html)</sup>. The MPC also offers a List API that can return catalog subsets such as main-belt asteroids or near-Earth objects, filtered by designation pattern<sup>[7](https://docs.minorplanetcenter.net/mpc-ops-docs/apis/list/)</sup>.
