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 planets, natural satellites, and maybe also smaller bodies such as asteroids and comets (though I suspect that both asteroids and comets will be better served by having their own template design).

The example on the far right is the recommended table format for minor planets. It is generated by the {{Infobox Planet}} template. 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 example.

Urhixidur wrote a nifty Windows tool (AstOrb Browser) that can greatly facilitate preparation of these. The most recent version can be downloaded from http://www.angelfire.com/pq/Urhixidur/index.html (at the bottom of the page, under the heading "Delphi 7 and Wikipedia"). Since version 1.4.4, it uses the {{Infobox Planet}} format instead of {{Minor Planet}}. It also automatically generates the footers mentioned below, and integrates the necessary diacriticals.

Some values require special attention, as they are not filled in by AstOrb Browser, or are filled in using default values (the default Diameter, Albedo and Density can be overridden, and will revise the dependent values accordingly):

  • The discoverer and discovered values can be obtained from the "Discovery" link, or from the List of asteroids.
  • The alt_names link should be followed to reach the MPC query form, whence you can obtain the alternative designations (for 61 Danaë, you'd enter "(61)"). Since this page has been broken for a long time now, you can reach the alt_names listing directly by specifying the URL http://scully.cfa.harvard.edu/~cgi/PDes?pm=05178 (for (5178) in this example).
  • The mp_category is defaulted to "Main belt", and should be changed as appropriate.
  • The dimensions can be replaced by more accurate/recent values, supplying the reference (this value should be entered in AstOrb Browser in order to recompute the mass, gravity and escape velocity accordingly).
  • The mass, surface_grav and escape_velocity should be marked with a ? if the density and/or dimensions are guesswork.
  • The guesswork albedo, should whenever possible be replaced by a more accurate/recent value, supplying the reference, as was done here (you should use <ref> instead of <sup>, however).

A few short-hand templates are useful when dealing with minor planets with provisional designations. They are Template:mp, Template:mpl, and Template:mpl-:

  • mp ("minor planet") saves you from typing <sub></sub> if you'd rather not: {{mp|15874|1996 TL|66}} or {{mp|(15874) 1996 TL|66}} = (15874) 1996 TL66.
  • mpl ("minor planet link") is used to write a link, like so {{mpl|15874|1996 TL|66}} or {{mpl|(15874) 1996 TL|66}} = (15874) 1996 TL66.
  • mpl- ("minor planet link, abridged") is used with numbered minor planets that have kept (so far) their provisional designations when one wishes to hide the number from inline display: {{mpl-|15760|1992 QB|1}} = 1992 QB1 (instead of (15760) 1992 QB1).
  • mp and mpl can also be used to either write out or create links to the provisional designations used for minor planet satellites (e.g. {{mpl|S|2000|1998 WW|31|1}} = S/2000 (1998 WW31) 1).

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

Template: {{Galaxy cluster}}

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 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.
