A more compact infobox, based on a this template has been suggested for the irregular satellites (e.g. S/2002 N 2). The reasons are given (and you comments are welcome) on the project page. Eurocommuter 13:40, 11 September 2006 (UTC)

jpl only mentions Sheppard, Jewitt, Fernandez, and Magnier as discoverer not Kowal and Roemer. Should we have all named or only Sheppard and Co.? -- Marsve 13:10, 16 Apr 2005 (UTC)
When looking at the orbital elements for Themisto, I can see large contradictions.
For example, for the semi-major axis, [1] gives 7.507 Mkm, [2] gives 7.284 Mkm, and this page gives yet another. Which sources are more accurate? JamesFox 17:49, 6 September 2006 (UTC)
The popular Sheppard page is based on the same source (Jacobson) but apparently not updated. Jacobson data (JPL) site are the most used ref in scientific papers for mean elements (integrated for at least 1000 years). Some papers do their own longer integrations to determine statibity or confirm some hypothesis on the origin. The osculating (Keplerian) elements for many satellites change very dramatically in short periods of time. Also, for newly discovered moons, the initial orbit elements are further refined and typically change a lot. Consequently, I believe we should quote Jacobson (JPL) as a matter of routine with a link for the Ephemeris (IAU) for today’s) orbital elements. I suggest to move this discussion to irregular satellites or the project. Please also see project page Wikipedia_talk:WikiProject_Astronomical_objects#A hundred or so irregular satellites.... My apologies I missed your post here; I haven’t got to this sat yet and it was not on my watchlist; it is not even cat as irregular satellite (see for example S/2002 N 1) for an updated example.

It was certainly thought to exist but unconfirmed for a long time. Please do not remove things without discussion. Mrwuggs 22:50, 16 October 2006 (UTC)
That's true, but most of the article is about how it was discovered, lost before it could be confirmed, and rediscovered, making the primary topic of this page the history of astronomy that surrounds it. Stacey 14:37, 18 October 2006 (UTC)
I'd like to bring this back up. The page for the hypothetical astronomical objects category gives the following definition: "Hypothetical bodies of the Solar system are astronomical bodies suggested or once believed to exist within the Solar system, but which have either not been proven to exist or been proven not to exist." Given the last clause, and that we have proof Themisto exists, either it doesn't seem to belong in this category or the category description needs to be changed. -- Patteroast 09:15, 10 February 2007 (UTC)
The image thumbnail here was present in the article, presumably because of the file name. However this is just the Celestia generic asteorid model and therefore provides precious little value to this article. Icalanise ( talk) 18:06, 22 July 2011 (UTC)
Hello fellow Wikipedians,
I have just added archive links to one external link on
Themisto (moon). Please take a moment to review
my edit. You may add {{
cbignore}}
after the link to keep me from modifying it, if I keep adding bad data, but formatting bugs should be reported instead. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}}
to keep me off the page altogether, but should be used as a last resort. I made the following changes:
When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{
Sourcecheck}}
).
