Occasionally, comets will break up into multiple chunks, as volatiles coming off the comet and rotational forces may cause it to break into two or more pieces. Please provide feedback on the SBN website. (The orbits of these comets are not determined accurately enough to unambiguously distinguish the same object after only two orbits.). 95P/Chiron (2060) The initial list of periodic comets was extracted from the 2003 version of the Catalog of Cometary Orbits (Marsden & Williams). In 1995, comet 73P/Schwassmann–Wachmann, broke up into several pieces and as of its last perihelion date, the pieces numbered at least 67 with 73P/Schwassmann–Wachmann C as the presumed original nucleus. List of Periodic Comets A periodic comet is given the designation "P". 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. Catalog of Short Period Comets. This is a list of 57P/du Toit–Neujmin–Delporte (2 entries) with all its cometary fragments listed at JPL's SBDB (see list). 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. There are also 27 Encke-type comets (ETCs), 14 Halley-type comets (HTCs), 5 Chiron-type comets (CTCs), and one long-period comet (i.e. To determine which objects to include in the list, we adopt the IAU definition for short-period comets.

A file containing the order in which the comets were designated as periodic (starting in 1995) is given here. Encke. 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. Giotto (flyby 1986), Vega 1 (flyby 1986), Vega 2 (flyby 1986), ICE (distant flyby 1986), Sakigake (distant flyby 1986) 2P/Encke. The 500 level numbers used in these catalogs denote comets that had only had one apparition at the time the catalog was published. 2.3 … Comet; Period (yrs) Perihelion (AU) Ashbrook-Jackson; 7.49; 2.316; Borrelly; 6.88; 1.365; Brooks 2; 6.89; 1.843; Bus; 6.52; 2.183; Ciffreo; 7.23; 1.70877; Encke; 3.28; 0.331; Forbes; 6.13; 1.44684; Gehrels 3; 8.11; 3.427; Giclas; 6.96; 1.84679; Halley; 76; 0.587; Harrington; 6.78; 1.572; Hartley 3; 6.84; 2.462; Holmes; 7.09; 2.177; Howell; 5.58; 1.40914; Kohoutek; 6.67; 1.785; Kojima; 7.85; 2.399; Lovas 2; 6.76; 1.462; … Please provide feedback on the MPC website. to Ecliptic Perihelion Passage.

This is a list of periodic comets that were numbered by the Minor Planet Center after having been observed on at least two occasions. Periodic updates to this list are obtained from IAU Circulars, Minor Planet Electronic Circulars and Central Bureau Electronic Telegrams. 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. Comet. This is a list of 73P/Schwassmann–Wachmann (68 entries) with all its cometary fragments listed at JPL's SBDB (see list). Upon rediscovery, a second (or third) name was added, and this new name is the one currently in use. "Periodic comet" is also sometimes used to mean any comet with a periodic orbit, even if greater than 200 years. 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. Once a comet's … 2.2 57P/du Toit–Neujmin–Delporte. A more detailed description of the table's contents is given following the table. A butterfly preserved and made perfect with a dart through it.
