Periodic Comet Names and Designations
This list was compiled for the Planetary Data System Small Bodies Node (PDS SBN) to provide a cross reference between a periodic comet's official designation and its name. For completeness, it also includes the previous names by which a comet may have been known, as well as the Belyaev/Carusi catalog identification numbers. A more detailed description of the table's contents is given following the table.
To determine which objects to include in the list, we adopt the IAU definition for short-period comets. This includes all numbered periodic comets (those observed on at least two apparitions) and unnumbered comets whose orbital periods have been determined to be less than 200 years. An exception to this is the sungrazing comets observed by SOHO, for which three apparitions are required. (The orbits of these comets are not determined accurately enough to unambiguously distinguish the same object after only two orbits.)
The initial list of periodic comets was extracted from the 2003 version of the Catalog of Cometary Orbits (Marsden & Williams). Periodic updates to this list are obtained from IAU Circulars, Minor Planet Electronic Circulars and Central Bureau Electronic Telegrams. The list is complete through the date given. A file containing the order in which the comets were designated as periodic (starting in 1995) is given here. Due to changes in policies regarding MPC updates around the start of 2012, entries from after that date are only added to the list when their orbital elements have included an epoch, suggesting that the orbits are well-determined.
Note: When this list was initially compiled there were a number of entries for which the serial number in the PDS Name was incorrect. On January 13, 2006 these were corrected to reflect the proper order in which they were designated as periodic. A list of the changes is given here. Also included are any subsequent changes and the reason they were made.

Notes about the table content
Official Designation
The official comet designation as assigned by the IAU Central Bureau for Astronomical Telegrams (CBAT). This is a unique identifier based on the year and month of the comet's discovery (see the Minor Planet Circulars 23803-23804 for details). For multiple apparition (numbered) comets, the principal designation is adopted from the Catalog of Cometary Orbits.
Orbital Period and Time of Perihelion
The orbital period (in years) and the date of perihelion corresponding to the principal designation are included to provide a backup for distinguishing between comets when an ambiguous name or designation is used. (e.g., 2P/ could refer to the official designation of Encke, or the Belyaev/Carusi designation of Tempel-Tuttle).
PDS Name
The name of the comet, derived from the name(s) of the discoverer(s). To ensure that each name is unique, a serial number has been appended to identify the different comets discovered by the same observer(s). In cases where historical numbers already exist, these have been retained. In cases where multiple comets were discovered after the CBAT and the Minor Planet Center (MPC) stopped using these numbers, they have been added, either in the order of the comet's identification as periodic or when it has been given an official name (whichever came second). All first discovery names have had a "1" appended to avoid the need for changing names at a future date if a second comet is discovered by the same observer(s) or by a new observer with the same name.
Note that in the case of Chiron and Echeclus, there are no serial numbers. This is because "Chiron" and "Echeclus" are the names that were assigned to these objects under asteroid naming conventions, not the name of the discoverers. Furthermore, there are currently eight periodic comets that have also been assigned numbers in the asteroid classification system:
95P/Chiron (2060)
107P/Wilson-Harrington 1 (4015)
133P/Elst-Pizzaro 1 (7968)
174P/Echeclus (60558)
176P/LINEAR 52 (118401)
282P/(323137)
288P/(300163)
362P/(457175)
Belyaev/Carusi ID
The designations used in the Belyaev et al. Catalog of Short Period Comets. The same designations were used and updated by Carusi et al. in their Long Term Evolution of Comets. These catalogs represent an independent numbering system that has been superseded by the official designations presented here, and only the numbers that deviate from the official designation are noted. The 500 level numbers used in these catalogs denote comets that had only had one apparition at the time the catalog was published. It is assumed that the user will not search for a comet using this designation.
Previous Name
Previous names usually come from an original discovery, after which the comet was lost. Upon rediscovery, a second (or third) name was added, and this new name is the one currently in use. Note that alternate names have only been included for comets that were rediscovered (and thus had their name changed) after 1950. There are two justifications for this restriction: First, there are a number of ambiguities and multiple rediscoveries before 1950, and avoiding the renaming of these comets simplifies the list. More importantly, however, there is not likely to be much significant literature regarding these older comets under their earlier names. After all, since the comets were lost, they were apparently not extensively studied after their original discovery. Most of the alternate names were found from the histories given in Comets: A Descriptive Catalog by Gary Kronk, as well as from Kronk's Cometography web site. Others were determined from changes in different versions of the MPC catalog in recent years.
