[edit] Stars

Do we have any idea of how many stars might be in the Local Group? -- Tarquin 07:19, 2 May 2005 (UTC)

There are about 10^11 stars in the Milky Way (See, for example, Binney & Tremaine, page 1) so figure for the group we're talking around 10^12, within a factor of about 3 or so. Even the number of stars in the Milky way contains a lot of conjecture, so I wouldn't expect a longer search to give a more exact number.--WilyD 8:45, Sept 29 2005 (EST)


[edit] Map

Where does the map come from? Who made it? What about taking the 3D map used in the german article?--CWitte 14:43, 9 Jun 2005 (UTC)

I would say the German map is better, but I don't know what other people have to say about that.DaMatriX

  • The map is from "Atlas of the Universe", without the z=0 plane drawn in. It does not list all the galaxies mentioned in the article. Those very close to the Milky Way await zooming in at the Atlas site, and some don't show at all, like [I]And IV[/I]. I don't find it at all useful. Someone should feed the coordinates into a general purpose (and free) 3D viewing program. —Długosz 14-Sept-2007. —Preceding unsigned comment added by Długosz (talk • contribs) 16:29, 14 September 2007 (UTC)

[edit] Merge from List of nearest galaxies

  • OPPOSE a list is useful by itself, and would clutter the Local Group article. And not everything on the list need be a Local Group member. 132.205.45.110 22:37, 13 January 2006 (UTC)
  • OPPOSE "Local Group" is an established astronomical term, with a clear definition of its member galaxies. A list is nice, but only as an additional overview, and might describe either more or less galaxies (depending on the range) than the Local Group. --84.178.157.201 11:19, 18 January 2006 (UTC)
  • OPPOSE I agree, it should remain separate. --JorisvS 12:00, 27 May 2006 (UTC)

[edit] More dwarf galaxies

Two more faint local group dwarfs - [1] - one in Canes Venatici, the other in Bootes. -- ALoan (Talk) 10:59, 10 May 2006 (UTC)

[edit] Size and distance

It's a nice, useful list. However, I miss certain things, especially the distance to the Milky Way Galaxy and the size of the Galaxy. It would a better list with this information. --JorisvS 12:02, 27 May 2006 (UTC)

  • Care to elaborate? The distance to the Milky way galaxy isn't an obvious number (perhaps zero, up to - 8kpc? maybe). And who cares what size the individual galaxies are? That's why they have individual articles .... isn't it? WilyD 22:43, 7 November 2006 (UTC)
