'''Periodic comets''' are defined for these purposes as those [[comet]]s having orbital periods of less than 200 years (also known as "short-period comets") ''or'' which have been observed during more than a single [[perihelion]] passage (e.g. [[153P/Ikeya-Zhang]]). (Note that "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 as [[P/2005 T5 (Broughton)]].

In nearly all cases, comets are named after their discoverer(s), but in a few cases such as [[2P/Encke]] and [[27P/Crommelin]] they were named for a person who calculated their orbits (the orbit computers). The orbits of periodic comets are especially tricky to calculate because of all the possible perturbations from every planet, and in the days before electronic computers some people dedicated their entire careers to this. 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's [[coma (cometary)|coma]] and tail.

Periodic comets sometimes bear the same name repeatedly (e.g. the nine Shoemaker-Levy comets or the twenty-three [[Near Earth Asteroid Tracking|NEAT]] comets); the IAU system distinguishes between them either through the number prefix or by the full designation (e. g. [[181P/Shoemaker-Levy|181P]] and [[192/Shoemaker-Levy|192P]] 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]] and [[C/1994 E2]] after Shoemaker-Levy 9.
__FORCETOC__


In [[Astronomical_nomenclature#Comets|comet nomenclature]], the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet which has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated &mdash;usually historical comets), or "A" for an object that was mistakenly identified as a comet, but is actually a [[minor planet]].

Some lists retain the "C" prefix for comets of periods larger than about 30 years until their return is confirmed (e.g. [http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2008+E1 C/2008 E1 (Catalina)] vs. [http://pdssbn.astro.umd.edu/comet_data/periodic_comets.html P/2008 E1 (Catalina 9)]).

:No problem. That was always the most likely explanation. The edit summary was not so much a complaint as an attempt to ensure that it didn't happen again. You appear to be doing a good job in trying circumstances on that article. Keep it up. [[User:Arbus Driver|-Arb.]] 09:06, 27 September 2007 (UTC)

::Your approach (direct Wikimapia text link followed by <nowiki>{{</nowiki>coord<nowiki>}}</nowiki>) works well in [[Jamaica_Province_of_the_Moravian_Church#Organisation|that article]] with one minor quibble: it would look better if the coords were displayed in a slightly smaller font - as things stand they seem to overpower the accompanying text.

Hello. As you are well aware, [[Wikipedia:External links]] does not condone external links in article body outside the External links section, and with links to geographical information services in particular, it instructs to give the information as coordinates only, not links to specific map services. WikiMapia is a great service, but [[User:Arbus Driver/WikiMapia Profile|you as an advocate of WikiMapia]] should try to understand that not everyone shares your enthusiasm about combining Wikipedia with a project that has incompatible goals, stucture, and terms of use.

Revision as of 13:44, 10 October 2008

Periodic comets are defined for these purposes as those comets having orbital periods of less than 200 years (also known as "short-period comets") or which have been observed during more than a single perihelion passage (e.g. 153P/Ikeya-Zhang). (Note that "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 as P/2005 T5 (Broughton).

In nearly all cases, comets are named after their discoverer(s), but in a few cases such as 2P/Encke and 27P/Crommelin they were named for a person who calculated their orbits (the orbit computers). The orbits of periodic comets are especially tricky to calculate because of all the possible perturbations from every planet, and in the days before electronic computers some people dedicated their entire careers to this. 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's coma and tail.

Periodic comets sometimes bear the same name repeatedly (e.g. the nine Shoemaker-Levy comets or the twenty-three NEAT comets); the IAU system distinguishes between them either through the number prefix or by the full designation (e. g. 181P and 192P 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 and C/1994 E2 after Shoemaker-Levy 9.

In comet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet which has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated —usually historical comets), or "A" for an object that was mistakenly identified as a comet, but is actually a minor planet.

Some lists retain the "C" prefix for comets of periods larger than about 30 years until their return is confirmed (e.g. C/2008 E1 (Catalina) vs. P/2008 E1 (Catalina 9)).
