message: *Should Wikilinks to "Gliese ###" stars be to "Gl ###" or to "Gliese ###"?  IMHO the latter is more desireable.  --Bletch 15:24, 30 Aug 2004 (UTC)
replies: text: IMHO the best way to proceed is to use full name for one-word abbreviations (Gliese instead of Gl in the case of original Gliese stars, Messier instead of M, A -> Abell and so on) and abbreviation for longer designations (NGC instead of New General Catalogue, HD instead of Henry Draper, etc.; no one uses those unabbreviated names anyway). For the same reason, newer Gliese-Jahreiss (sp?) stars should be GJ ####.--Jyril 13:41, 2 May 2006 (UTC)

message: In this table the value of magnitude at which the star appears on the terestrial sky may not be forgotten! I provided for this important value a column! Please add the values!
:All of the data for stars less than 13 parsecs is now updated with Hipparcos data using proper motions to bring it into line with J2000.0. The magnitudes of some binary stars are integrated on some of the Hipparcos entries, so have largely used a different source for those. The exception is Xi Ursae Majoris A&B, which don't have any Hipparcos data (despite being catalogued as HIP55203.) Richard B 00:47, 29 November 2005 (UTC)
thread_title: Add Magnitude of stars as seen from earth

message: I'm not quite clear why somebody set the precision of the R.A. coordinate to hundredths of a second of arc. Under the very best seeing conditions and a decent telescope, you're lucky to be able to resolve a second of arc, never mind a hundredth. I would think rounding to a tenth of a second would be more than sufficient for the purposes of an encyclopedia. :) — RJH 16:17, 30 April 2006 (UTC)
replies: text: It's actually not 0.01 arcsec. RA is measured in hours, minutes, seconds - not degrees, minutes, seconds. 1 second of RA is equivalent to 15 seconds of declination at the equator (and 15 arcseconds). 0.01 seconds of RA is therefore equal to 0.15 arcseconds (again at the equator) - so it's actually rounded to worse than 1/10 arcsecond already.

thread_title:  RA precision 

message: Excuse my naivety in astronomy... but the closest star to earth is Proxima Centauri which is strangely abscent from the chart. Is this because it has been grouped with Alpha Centauri A & B somehow? Enigmatical 02:37, 5 May 2006 (UTC)
replies: text: This is a list of nearest bright stars. Proxima Centauri is a very dim star. It is visually dimmer than most stars on the list even as seen from Alpha Centauri itself.--Jyril 05:09, 5 May 2006 (UTC)
thread_title:  Proxima Centauri? 

message: The following statement was added to the text:
:At roughly 50 light years, the sun is no longer visible to the naked eye.
In this article, the Sun is listed with an absolute visual magnitude Mv of 4.80. Per the absolute magnitude article, at a distance of 50 light years, the apparent magnitude m of the Sun would be:
: \begin{smallmatrix}m\ =\ M_v\ +\ 5((\log_{10} D) - 1)\ =\ 4.80\ +\ 5((\log_{10} 15.33) - 1)\ =\ 5.72\end{smallmatrix}
where D is the distance of 50 ly in parsecs (= 15.33). This result is above the limiting magnitude for a dark sky, which is 6 (or lower depending on the observer).
Thus, unless I am mistaken, I think the statement is in error, so I removed the statement from the article.—RJH (talk) 17:57, 17 February 2010 (UTC)
