== Third party references ==

I note that this article has no third party references at all. I think the concept of the article is useful, but it's misleading and uncited to say that the IAU (1976) System of Constants (a specific document) is the generic "astronomical system of units". This article covers a number of units which are used for convenience in astronomy, all of which are recognized by standards bodies and common usage as real units. Putting that in one article is helpful, but framing it as a single, coherent system of units is a little misleading, I think. —Alex (] | ] | ]) 23:24, 13 July 2015 (UTC)

Merge other mass articles with this one?

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section.

With "concerns" about the stubbyness of some mass articles, should the Solar mass article be merged into this?

Should other mass articles; Jupiter mass, Earth mass, Lunar mass be merged into this article?

This could be done under a heading "Other units used in Astronomy". HarryAlffa (talk) 11:32, 21 September 2009 (UTC)

Solar mass

The following is a closed discussion of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the proposal was no merge

The above discussion is preserved as an archive of the proposal. Please do not modify it. Subsequent comments should be made in a new section on this talk page. No further edits should be made to this section.

Jupiter mass

Earth mass

Lunar mass

Discussion

I would prefer a separate article on planetary mass rather than merging them here: they are empirical quantities rather than a system of units. Physchim62 (talk) 08:33, 22 September 2009 (UTC)

Sounds good to me.TStein (talk) 15:46, 22 September 2009 (UTC)
Is the mass of Jupiter an IAU standard? I didn't see it listed in the referenced document.—RJH (talk) 16:50, 22 September 2009 (UTC)
The mass of Jupiter is not a standard. The best estimates come from it being an adjusted parameter in solar system ephemerides, in which the unit of mass is the solar mass. You can also create separate "Jovian" ephemerides, but I think the accuracy of these is much less that the ones based on the solar system as a whole. Physchim62 (talk) 19:39, 22 September 2009 (UTC)
Alright, we have Physchim62 and TStein at this page, and at Talk:Jupiter we have Kheider and myself in clear support of a merged planetary mass article, to merge Jupiter mass and Earth mass. I would say this is probably sufficient consensus: are there any other suggestions, or any objections? Iridia (talk) 00:34, 23 September 2009 (UTC)
What I suggest is that I create Planetary mass – I say me simply because I happen to know my way around the sources to a certain extent – but without explicitly merging the other articles. Then we can have another couple of days of discussion as to where things go before taking the plunge. Merging is relatively easy, but demerging afterwards is more difficult, so I don't think we need to be in a rush. There's enough material to create an article on planetary mass from scratch, even if we end up never doing any merges, and I can get a first version out this afternoon (European time). Physchim62 (talk) 11:54, 23 September 2009 (UTC)
Comment shouldn't it be planet-based mass units? (or similar) 76.66.197.30 (talk) 04:57, 24 September 2009 (UTC)

It took me a bit longer than I thought, but planetary mass is now up and open for improvement! Physchim62 (talk) 13:00, 26 September 2009 (UTC)

This poll is closed, as the merge suggestion is replaced by a new proposal at planetary mass, and per a slight consensus here. 76.66.197.30 (talk) 14:17, 29 September 2009 (UTC)
The discussion above is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.

Digit?

I see no mention is this article of the digit, from Classical times until (very?) recently one-twelfth of the apparent diameter of the sun or moon and used, I believe, in measurement of eclipses. Has this been replaced by some other unit, or simply forgotten? Justlettersandnumbers (talk) 17:10, 26 August 2011 (UTC)

Length

Are Lunar radius, Earth radius, Jupiter radius and Solar radius notable enough to be worth mentioning in this article? These units appear in popular science articles as well as in scientific papers. --Artman40 (talk) 13:00, 23 June 2014 (UTC)

Third party references

I note that this article has no third party references at all. I think the concept of the article is useful, but it's misleading and uncited to say that the IAU (1976) System of Constants (a specific document) is the generic "astronomical system of units".
