Why is beta brighter than alpha? Nik42 06:05, 17 September 2006 (UTC)
Bayer designations often don't follow the alphabetical/decreasing brightness rule. The brightness measurements were made by eye which explains some of the discrepancies. In addition, they often follow some asterism (like is the case in Ursa Major and Sagittarius) and therefore the alpha star may be far from being the brightest star.--JyriLtalk 00:14, 31 December 2006 (UTC)
"Beta" was not brighter than "Alpha" in Bayer's Uranometria (1603). Bayer wrote that three stars ― Alpha, Beta, and Gamma Trianguli were same class (not magnitude) "Quartae Diff[erentiae]" in the star list of the constellation "TRIANGVRVM". Alpha Trianguli is prior to Beta Trianguli on their position within the constellation Triangulum. It is same case of the Plough in Ursa Major and "Castor and Pollux" in Gemini, not Sagittarius.--Bay Flam 08:24, 8 May 2007 (UTC)
(1) Give a source for the claim. (2) If it is changed, it will be in future. For now, the name of the constellation is Triangulum.--JyriLtalk 00:14, 31 December 2006 (UTC)
Nope, the "official" name is Triangulum, not Triangulum Borale. I've never ever heard of "Triangulum Borale". Said: Rursus 20:08, 4 May 2007 (UTC)
Surely Triangulum is official name of this constellation. "Triangulus Septentrionalis" (sic), the Northern Triangle with TRIANGVRVM found in the star list of Bayer's Uranometria. Please see above.--Bay Flam 08:24, 8 May 2007 (UTC)
"nearly isosceles" is in the lede, but its shape is not mentioned in the body text. Given that the lede is a summary, my own view is that "nearly" could be dropped in the lede, but i decline to take responsibility for someone more pedantic than myself seeking to have this reversed during an FAC :-)

I would change "the first quasar observed" to "the first quasar ever observed", I just think that scans more clearly.
"Recent measurements of its motion indicate that it is moving at 190 kilometres (120 mi) per second in the direction of the Andromeda Galaxy, which has led astronomers to surmise that it may actually be orbiting the larger galaxy". Since when did something move towards another thing, when it is orbiting around it? What is meant here?
Took a while, couldn't track down the book, but got the paper which first mentioned it - it is about escape velocities of the larger object (Andromeda) but also warns of uncertainty in distances/margins of error to these galaxies and stops short of proposing it is a satellite. However a 2013 study does so I have added it here instead. Cas Liber (talk·contribs) 12:39, 2 October 2013 (UTC)
Sorry, but february isn't 45 days before the summer solstice!
Aha, the sun is in it at a different time - the two are not related per se. Given the confusion I have removed that as not germane to the article (as it refers to the Way of Enlil and not the Plough. Cas Liber (talk·contribs) 02:45, 18 November 2013 (UTC) used "which" instead of a participle to hopefully delineate it better. Cas Liber (talk·contribs) 02:47, 18 November 2013 (UTC)
