Comets with less than 200 year orbital periods

For a list of numbered periodic comets, seeList of numbered comets.

Periodic comets (also known as short-period comets) arecomets withorbital periods of less than 200 years or that have been observed during more than a singleperihelion passage^[1] (e.g.153P/Ikeya–Zhang). "Periodic comet" is also sometimes used to mean any comet with a periodic orbit, even if greater than 200 years.

Periodic comets receive a permanent number prefix usually after the second perihelion passage, which is why there are a number of unnumbered periodic comets, such asP/2005 T5 (Broughton) [it]. Comets that are not observed after a number of perihelion passages, or presumed to be destroyed, are given the D designation, and likewise comets given a periodic number and subsequently lost are given [n]D instead of [n]P, such as3D/Biela or5D/Brorsen.

In nearly all cases, comets are named after their discoverers, but in a few cases such as2P/Encke and27P/Crommelin they were named for a person who calculated their orbits (the orbit computers). The long-term orbits of comets can be difficult to calculate due to errors in the known trajectory that can accumulate fromperturbations from the planets. Even so, quite a few comets were lost because their orbits are also affected by non-gravitational effects such as the release of gas and other material that forms the comet'scoma and tail. Unlike along-period comet, the nextperihelion passage of a numbered periodic comet can be predicted with a high degree of accuracy.

Periodic comets sometimes bear the same name repeatedly (e.g. the nine Shoemaker–Levy comets or the twenty-fourNEAT comets); the IAU system distinguishes between them either through the number prefix or by the full designation (e. g.181P and192P/Shoemaker–Levy are both "Comet Shoemaker–Levy"). In the literature, an informal numbering system is applied to periodic comets (skipping the non-periodic ones), thus 181P and 192P are known as Comet Shoemaker–Levy 6 and Comet Shoemaker–Levy 1, respectively. Non-periodic Shoemaker–Levy comets are interleaved in this sequence:C/1991 B1 between 2 and 3,C/1991 T2 between 5 and 6,C/1993 K1 andC/1994 E2 after Shoemaker–Levy 9.

Incomet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet that has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated —usually historical comets), "I" for aninterstellar object, or "A" for an object that was either mistakenly identified as a comet, but is actually aminor planet,^[1] or for an object on a hyperbolic orbit that does not show cometary activity.^[2] Some lists retain the "C" prefix for comets of periods larger than about 30 years until their return is confirmed.^[3]

List of unnumbered Jupiter-family comets

[edit]

WhileJupiter-family comets are officially defined by 2 <T_Jupiter < 3, they can also be loosely defined as any comet with a period of less than 20 years, a relatively lowinclination, and an orbit coinciding loosely with that of Jupiter. These comets are often patchily observed, as orbital interactions with theplanet often cause comets' orbits to becomeperturbed, causing them to not be found at the expected position in the sky and subsequently lost. Additionally, their low cometaryalbedos and frequent proximity to theSun compared toOort Cloud comets cause them to much more quickly become depleted of volatiles, making them comparativelydimmer than comets with longer orbital periods.
