I feel that the standard infobox for moons above is inadequate for the irregular satellites given typically limited amount of available data, very perturbed orbits, numerous assumptions etc. I suggest to adapt a shorter infobox for the irregulars following a few simple guidelines
For a sample please see here. I’d like to apply it first to the Neptune’s irregulars currently without infoboxes anyway. Eurocommuter 13:19, 5 September 2006 (UTC)

Thank you for the feedback, George. In detail:
Sources; I’ve got a core list here.
Example of refs: Ananke
I’ll implement your comments in the next draft. Your comments are highly appreciated. TNO infobox could be the next one to be reviewed. Regards Eurocommuter 15:10, 5 September 2006 (UTC)

Draft template for the infobox is here. The example of application is there. Eurocommuter 09:43, 6 September 2006 (UTC)
There is usually a "discover" section in the comet infobox, but it isn't displayed. Why isn't it showing? Also, why isn't there a section for argument of perihelion, etc? Thanks. AstroHurricane001( Talk+ Contribs+ Ubx) 00:24, 18 January 2007 (UTC)
The minor planets example is out of date. All or almost all the most significant ones (hundreds) now use Template:Infobox Planet instead. Deuar 16:51, 30 March 2007 (UTC)
Almost none of the infobox data for the 8 planets show any citations. More often than not the data disagrees with NASA statistics from the External Links, even when the "epoch 2000" is accounted for. Where do the data come from, and how can we check for typos? From my amateur's point of view, it looks as if we need to get the basic facts straight before we worry about comets, asteroids and such.

User:Sardanaphalus has proposed moving Template:Infobox Planet to Template:Infobox Nonstellar body (or some other generic term). Please join the discussion at Template talk:Infobox Planet#Template's name. -- Ckatz chat spy 05:49, 8 March 2008 (UTC)
In all the astronomical Infoboxes available in each of the text boxes using non-astronomical nomenclature and inconsistent units.
The units to describe double stars and binary stars of arcseconds is " or arcsec. The units to describe the apparent dimensions of deep-sky objects I.e. Galaxies. Nebula, etc. is in arcmin or ' . NOT arcmins)
Use superscript –1, not solidus /, for units: e.g. km s–1 not km/s.
Standard Units are;
Mean Density g cm-3 NOT g/cm3
Velocity m s-2 NOT m/s2 OR km s-2 NOT km/s2
Parallax The unit is in mas. NOT milliarcseconds
Proper Motion mas yr-1 NOT mas/yr
Age Is either 'a', yr. or years. S.I. standard is "a" However a, in astronomy it can be confused with the semi-major axis 'a' in binaries.
Energy J (Joules) NOT ergs (Non-SI) W (Watts) but sometimes used J.sec-1
DIstances
Solar System A.U. not AU, or at least AU. km. (use Scientific Notation i.e. 1.4×109 NOT "Ga"
Stars parsec (pc.) is preferred over light-years (ly.), and pc. over ly.
Planetary Nebulae Distance in kpc.
Globular and Open Clusters Distance in kiloparsec (kpc). NEVER kly (kilolight-years
Milky Way Distance in kiloparsec (kpc). NEVER kly (kilolight-years
Galaxies Megaparsecs (Mpc.) NOT Mly.(Megalight years)
Metallicity
Unit is [X/H] and is a value between whole number and fraction. Ie. 0.20 or 1.25, NOT in %percentage ( often the more specific ratio. I.e. [Fe/H] or [H/He] is used instead of [X/H] )
Orbital elements There are seven elements that describe the orbit. These are in the following order
P Period yr. (years)
T Periastron (Epoch of passage through Periastron) yr,. (years)
a Semi-major axis (in arcsec)
i Inclination (measured in degrees or °)
Ω Descending Node (measured in degrees or °) (If Ω* it is the Ascending Node)|
NOTE : In the Solar System it is called the "Longitude of the Node"
ω Longitude of periastron (measured in degrees or °)
NOTE: Presently Missing in starbox example for visual binary orbit
Ref. [ 6th Orbit Catalog Text ]
(Units are normally "d" = days, "y" = years, "c" = centuries)
Solar Values Ie. Mʘ NOT Mʘ
Lʘ NOT Lʘ
Rʘ NOT Rʘ
NOTE: The < math > equation should be M{\odot}=1.98892\times10^{30}\hbox{ kg}
NOT M{\odot}=1.98892\times10^{30}\hbox{ kg}
The problem is subscripting the solar mass symbol, is that it is the central dot is unable to seen. Difficult to interpret if say the symbol was earth mass (for example)
Starbox catalogue should have an order based on order of importance.
Greek designation is first, them Flamsteed Designation next. Then followed by;
HIP FK5 HR HD SAO CP CD LHS Gliese, etc.
NOT in the order: {{ Starbox catalog | | names = α1 Cen, HIP 71683, FK5 538, HR 5459 HD 128620, SAO 252838
CP -60° 5483 LHS 50, A, Gliese 559A, YPC 3309.00
According to WP:DATE errors and uncertainty are written as;
"Uncertainties can be written in various ways:; Value/±/uncertainty/×/10n/unit symbol (e.g. 1.534±0.35×1023 m "
There is not spaces between the number and the error/uncertainty, as they are both implicitly related.
Also If you use scientific notation, according to the WP:MoS should be separated by the 'multiplication sign.
However, the units must be as specified in S.I. units.
I.e, As 1.02 ± 0.08 mas. This should be 1.02±0.08 mas or if need be 1.02±0.08 milliarcsec
Looking at the astronomical text throughout Wikipedia the units used are very confusing and are non-standard combinations.
I also think this is an important need an WP:Astronomy_Units Page, which gives the uses standard usage, and with a list of redundancy by highest to lowest in preference(s). Adoption can be made from some Astronomical Style Guide, as used with the major journals of astronomical papers. Another good general source and summary is something like "Norton's Star Atlas 2000.0" in the Appendix "Units and Notation"even or the yearly "The Astronomical Almanac."
I added a the template Template:mpcat which you can use like this:
or like this
I put it into a few infoboxes in some of the articles I have been working on recently. I am suggesting we begin switching all of the infoboxes over to this new system, as well as ammend the the instructions on the infbox page to include these. Here is a list of articles which use this new system I am proposing: 4660 Nereus, 1862 Apollo, 1999 UJ7, as well as about 15 others (check my user page for a list of asteroids using this template). Let me know if you have any ideas to improve the template. - AndrewBuck ( talk) 06:30, 23 April 2009 (UTC)
I notice that Inforbox planet has a line for " mean anomaly", and maybe others do as well. But what does that mean? At what epoch? The mean anomaly of an object is constantly changin'. If we're gonna put this line, then we should specify the epoch. Eric Kvaalen ( talk) 04:35, 31 July 2015 (UTC)
