Talk:Vulpecula

Cat
I've removed cat Astronomy from this article since the Constellation category is already a member (eventually). Ian Cairns 19:19, 18 May 2005 (UTC)

Area
Sources differ on how many square degrees: some say 268 and some say 278. I have made the change to 268, because more sources say 268 (especially if you exclude Wikipedia mirrors), and also some sources that say 268 give higher precision: 268.2 or 268.165.

The only way to know for sure would be to look up Delporte's exact 1930 boundaries and do the calculation using spherical trigonometry. -- Curps 18:39, 6 August 2005 (UTC)


 * Actually, there's another way to be reasonably confident of the result: the total area of the sky is 4&pi; steradians, or 4&pi; &times; (180/&pi;)2 = 41252.961 square degrees. The total areas of all 88 constellations have to add up to this. Putting the information from List of constellations by area into a spreadsheet, we get the right result if the area for Vulpecula is 268 degrees, not 278 degrees. -- Curps 19:20, 6 August 2005 (UTC)

This change also affects the following pages: Columba (54th by area, not 55th) and List of constellations by area. -- Curps 18:42, 6 August 2005 (UTC)

Distance
Where does the figure for the distance come from? According to the Bright Star Catalogue Alpha Vul's parallax is 0.014" which translates into 233 light years. I won't change it for now but would like to know the source of the existing value. --Kalsermar 16:06, 14 September 2005 (UTC)
 * Obviously Hipparcos. The BSC values are long out of date. Skeptic2 (talk) 22:37, 14 October 2008 (UTC)

Disambiguation?
May I suggest a disambiguation page, for people looking for information on the Trichosurus vulpecula? —Preceding unsigned comment added by 220.239.32.109 (talk) 14:36, 14 January 2008 (UTC)

NGC 7052 is an elliptical galaxy
The page states that NGC 7052 is an edge-on spiral galaxy, it is really an elliptical. 108.18.181.48 (talk) 20:40, 27 June 2015 (UTC)
