View source for Wiki143:WikiProject Astronomical objects/Infoboxes

This page is where work is being done to come up with a generic table template to be used for organizing a list of facts about various astronomical bodies such as [[planet]]s, [[natural satellite]]s, and maybe also smaller bodies such as [[asteroid]]s and [[comet]]s (though I suspect that both asteroids and comets will be better served by having their own template design).

=== Main template: Infobox planet ===
{{main|Template:Infobox planet}}

This template has been designed for the presentation of information on non-stellar astronomical objects: planets (including extrasolar planets), dwarf planets, moons and minor planets. For {{section link||Extrasolar planets}} and {{section link||Comets}}, alternative templates exist.

The adjunct infobox-example is generated by the {{tl|Infobox planet}} template for the minor planet {{mpl|(78799) 2002 XW|93}}. This example uses the following wikicode:

==== Note ====
* for a clean syntax, citations should be listed separately in the article's "References" section {{crossreference|(see {{section link||References: segregated citations used in infobox}})}}.
* The above example uses a basic parameter selection for minor planets with some parameters such as {{para|image}} and {{para|mass}} left empty.
* The template has an optional ''astron'' argument whose default value is ''helion''; this allows its use to describe asteroid moons, as in the [[S/2000 (1998 WW31) 1|S/2000 ({{mp|1998 WW|31}}) 1]] example.
* Formatting unnamed minor planets
** use {{tl|mp}} to format unnamed minor planets: <code><nowiki>{{mp|(78799) 2002 XW|93}}</nowiki></code> displays as {{mp|(78799) 2002 XW|93}}
** use {{tl|mpl}} to add a link: <code><nowiki>{{mpl|(78799) 2002 XW|93}}</nowiki></code> displays as {{mpl|(78799) 2002 XW|93}}
** use {{tl|mpl-}} to suppress the designation's number part: <code><nowiki>{{mpl-|78799|2002 XW|93}}</nowiki></code> displays as {{mpl-|78799|2002 XW|93}}
** for more details {{crossreference|see [[:Template:mp/doc]]}}
** to modify the article's title with subscripted index, use <code><nowiki>{{DISPLAYTITLE:}}</nowiki></code>. See  first line in the [https://en.wikipedia.org/w/index.php?title=(78799)_2002_XW93&action=edit#editform edit window] of article {{mpl|(78799) 2002 XW|93}}

As discussed above, [[comet]]s might be served better by a different template. Here is a suggestion for {{tl|Comet}} we can toy with until we are happy with it. [[User:Awolf002|Awolf002]] 00:23, 5 December 2005 (UTC)

This example table should be edited and used for galaxy groups, clusters, and superclusters.   It automatically assigns the article to [[:Category:Galaxy clusters]].

The sample data for this group was taken from the [http://nedwww.ipac.caltech.edu/ NASA/IPAC Extragalactic Database (NED)] on 2006-09-18.  However, NED may not be the best reference for all galaxy groups.  It can be reliably used for compact groups such as the one in this example, and it can be used reliably for most Abell clusters and other moderate and high-redshift clusters, but it should be used cautiously (if used at all) for nearby galaxy groups such as the [[M81 Group]].
