The example on the far right is the recommended table format for minor planets —note the recommended unit links. It is generated by the {{Minor Planet}} template (now replaced by the {{Infobox Planet}} with the minorplanet flag; see below). 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 that can greatly facilitate preparation of these. The most recent version can be downloaded from http://www.bigfoot.com/~D.U.Thibault (at the bottom of the page, under the heading "Delphi 7 and Wikipedia").

A more compact form of this with just the orbital elements is on the near right {{Minor planet}} (note the lower case 'p'). The two are incompatible at the moment, something which Nicholas intends to fix one day.

A few short-hand templates are useful when dealing with asteroids with provisional designations. They are Template:mp, Template:mpl, and Template:mpl-. Mpl ("minor planet link") is used to write a link, like so {{mpl|(15874) 1996 TL|66}} = (15874) 1996 TL66, whilst mp ("minor planet") saves you from typing <sub></sub> if you'd rather not: {{mp|(15874) 1996 TL|66}} = (15874) 1996 TL66. Mpl- is used with numbered asteroids that have kept (so far) their provisional designations: {{mpl-|15760|1992 QB|1}} = 1992 QB1 instead of (15760) 1992 QB1.

Footers[edit]

Particularly useful are {{MinorPlanets Navigator}} and {{MinorPlanets Footer}}. Scroll down beyond the table to the right to see examples of these.

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)
