Talk:Summer Triangle

(random heading)
The southern triangle is drawn upon the southern hemisphere's celestial sphere.
 * The constellation named The Southern Triangle has an article HERE! ... said: Rursus (bork²) 12:52, 2 May 2009 (UTC)

Pardon I do not edit frequently. Something seems wrong on this page. Vega is the apparently brightest star in this constellation, but the data in the table seems to indicate that Deneb is brightest. Are the stars labeled wrong in the picture or are the data in the table wrong? Can someone either fix this or explain this? Betweendust (talk) 05:08, 15 July 2009 (UTC)


 * Deneb is the most luminous of the three stars but it is much farther away than the others. The *apparent* magnitude of Vega is greatest of the three. The table is correct. Skeptic2 (talk) 09:17, 17 July 2009 (UTC)

Thanks. I did not understand the scale of Apparent Magnitude. —Preceding unsigned comment added by Betweendust (talk • contribs) 04:30, 2 August 2009 (UTC)

Circumpolar stars
About 10-14,000 years ago, these would have been circumpolar stars in the northern sky. See pole star for maps.&mdash;RJH (talk) 20:48, 29 September 2009 (UTC)


 * No, +14,000 yr into the future they will be (see the plus sign in File:Precession N.gif), but only north of about 60° N. Rursus dixit. ( m bork3 !) 19:31, 10 March 2010 (UTC)

There is no "Autumn Triangle"
There is no commonly identified asterism or 'folk star pattern' known as the "Autumn Triangle". Previous links did not point to an article in any case. It is pointless to have a link to a non-existent article about a non-existent star pattern. — Preceding unsigned comment added by 70.192.7.151 (talk) 05:44, 20 August 2013 (UTC)


 * Autumn Triangle is described at Autumn_Triangle as The Hamal, Diphda, Alpheratz triangle is given the name Autumn Triangle., so either that needs to be removed as unsourced, or allow the redirect link to stay. 05:54, 20 August 2013 (UTC)


 * Thanks. I didn't see that final sentence in the asterism article. It carried a 'citation needed' tag already so I have deleted it there, too. There is no common asterism known as the "Autumn Triangle". It was perhaps an invention of a small group who decided to add it to Wikipedia. For reference, hit the Google Books Advanced Search page. Search on the phrase "Summer Triangle" first. Set the dates for 1905 through 2005. You will find literally hundreds of books discussing the Summer Triangle all the way back to 1913 (that early reference should probably make its way into this article, incidentally). Do the same for "Autumn Triangle". The only hits for that phrase are accidental and/or unrelated to astronomy. This phrase is a Wikipedian coinage --not a real thing. — Preceding unsigned comment added by 70.192.7.151 (talk) 21:05, 20 August 2013 (UTC)


 * I also couldn't find any sources, except in reference to the summer triangle, so I redirected Autumn Triangle here. Tom Ruen (talk) 21:35, 20 August 2013 (UTC)

Visibility
It's so badly named. Even at my location (latitude 52.75N), Vega and Deneb do not set, and Altair is visible in the evening all through autumn, and doesn't finally disappear until January- by which time it has reappeared in the dawn sky. Even though it's not far north of the celestial equator, it is about 30° north of the ecliptic so is always well away from the sun, and above the horizon for longer when the sun is south of it in midwinter. The whole asterism is actually visible all year at mid-north European latitudes. Walshie79 (talk) 20:02, 21 December 2016 (UTC)
