Notes
The discovery table consist of the following fields:
- Astronomers and Institutions: links to the corresponding article about the discovering astronomer or institution on Wikipedia. If not linked, the displayed name should be a redirect to this list. For example, the page Masanao Abe forwards to the anchored table row List of minor planet discoverers § M. Abe using the astronomer's MPC-name as ID.
- Discoveries: displays the total number of discovered and co-discovered minor planets made by the discoverer (numbered bodies only). It links to the corresponding "Discovery by..." category, which are subcategories of Category:Discoveries by astronomer and Category:Astronomical discoveries by institution, respectively. These categories do not contain discoveries for which no page on Wikipedia exists. Astronomers with only a few discoveries often do not have their own discovery-category (redlinks). For those who have discovered only one single minor planet, the link in the discovery column directly points to the corresponding entry in the list of minor planets. There are typically no linked categories for astronomers with an unknown first name.
- DOB–DOD and Observatory code: displays the date of birth and death for astronomers, and alphanumeric IAU code(s) for institutions, respectively.
- Country: nationality of the astronomer or location of the discovering dedicated institution, respectively. Some discoverers have assigned two flags, with the first being the most appropriate to allow for a sensible sorting by country.
- Link-label; info, links and, notes: The link-label is used for piped discoverer links, intended for a consistent usage in minor-planet object articles and in the List of minor planets (see index). After the link-label, additional information is given: this includes links to external sources (Src), links to the MPC database (see here) for objects discovered or co-discovered by the astronomer, and trans-wiki links to existing articles on French, German and Italian Wikipedia. (The link-label should be separated by a semi-colon from all other information).
- Name(s) at MPC: displays the name of the discoverer as used by the MPC (non-diacritical version; where the abbreviated first name is written before the family name). Some discoverers have multiple names due to inconsistencies and typos.
- Cite: minor-planet discoverers are often honored with the naming of (one or several) asteroids by their colleges. The associated citation typically gives the discoverer's full name, his or her date of birth and additional biographical information.
