Merge other mass articles with this one?

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

  • Oppose I think there is enough out there that it can be kept as a standalone article. 76.66.196.139 (talk) 06:06, 22 September 2009 (UTC)
  • Oppose If there's one "astronomical mass" article that should remain independent, it's this one. The solar mass effectively serves as the standard for all the other masses. Physchim62 (talk) 08:33, 22 September 2009 (UTC)
  • Oppose This is quite a commonly used mass and the standard for stellar masses in addition to masses of black holes and galaxies. There are enough users who would want to know about solar mass with out the extra 'baggage' of other less commonly used masses. From the stand of precedence all other standard units have their own separate pages. TStein (talk) 15:40, 22 September 2009 (UTC)
  • Oppose This one is fine by itself. There's a clear distinction in astronomy between the units used at stellar scales and those used at planetary scales. Iridia (talk) 00:21, 23 September 2009 (UTC)

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)
