The "Akkadian" line info should be deleted entirely; it has nothing to do with Capella and is seriously out of date. What the writer has transliterated as Dilgan iku should be read: Sumerian aš.iku "1 iku (measure)" lent into Akkadian as ikû. An iku is the basic Sumerian measure of square area, ca. 3528 sq. meters. The celestial iku refers to the big square figure within the constellation Pegasus, i.e. α, β, γ Pegasi plus α Andromedae.

The claim that Capella is part of an aboriginal constellation is puzzling. If Capella is very close to the Pole Star, how is it visible in the southern hemisphere? —Preceding unsigned comment added by 66.165.176.60 ( talk) 17:06, 15 September 2008 (UTC)
Unreferenced material re Persian names moved from article: "In Persian literature, Capella (Bozbān, Ayyuq) is a metaphor for a huge distance and also the light red colour...Other names used by other cultures include: ... in Persian, بزبان, Bozbān (English: goat-keeper) and نگهبان, Negahbān (English: guard)..."

Is anyone working on the issues brought up in the GAN review? It's been a week, and nothing has been done. Unless something happens in the next day or two, I will fail the article. Ealdgyth - Talk 18:48, 5 March 2009 (UTC)
Capella (α Aurigae, α Aur, Alpha Aurigae, Alpha Aur) is the brightest star in the constellation Auriga, the eleventh brightest star in the night sky and the third brightest star in the northern celestial hemisphere, after Arcturus and Vega
Why is Sirius not in the above list? Jprw ( talk) 21:46, 19 October 2012 (UTC)
The result of the move request was: moved per request. Favonian ( talk) 17:10, 9 March 2014 (UTC)
– Looking at the subjects listed at Capella, it strikes me that the star is far more notable than any of them, and hence I propose the star is moved to Capella and the list is moved to Capella (disambiguation). I note that the original article from 2002 to 2004 was mainly about the star, until December 2004 when it was part disambiguationand then split here to make the star article. Anyway, discuss away Cas Liber ( talk · contribs) 08:30, 2 March 2014 (UTC)
The opening paragraph states: "Although it appears to be a single star to the naked eye, it is actually a star system of four stars in two binary pairs. The first pair consists of two bright, large type-G giant stars, both with a radius around 10 times that of the Sun and two and a half times its mass, in close orbit around each other. Designated Capella Aa and Capella Ab, these two stars have both exhausted their core hydrogen fuel and become giant stars, though it is unclear exactly what stage they are on the stellar evolutionary pathway."
But under "Characteristics" it says: Aa Spectral type K0III[4] Ab Spectral type G1III[4]
So Is Capella Aa a type G or a type K star? — Preceding unsigned comment added by 86.155.239.6 ( talk) 14:42, 26 November 2015 (UTC)
The interesting info that Capella used to be the brightest star in the sky around 160k-210k years ago is sourced to "Schaaf 2008" but there's no proper reference to just what article this is. Some reference note that used to be placed before the current notes 21-22 has been removed by accident, and those two references have become orphaned. 83.251.170.27 ( talk) 13:53, 7 March 2016 (UTC)

The article says Alpha Centauri is the nearest bright star. Surely it should be Aldebaran? |

Hello fellow Wikipedians,
I have just modified one external link on Capella. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

@ Lithopsian:, do you think there is anything else missing from this article before throwing it to the wolves at FAC? cheers, Cas Liber ( talk · contribs) 23:21, 16 March 2017 (UTC)
So far as I know, a Hertzsprung-Russell diagram has temperature = color as the x-axis. There can't be two colors for one kelvin temperature. But the diagram in this article has a yellow line next to the red line for the red giant branch. I think this must be an error. Wnt ( talk) 11:29, 21 March 2018 (UTC)
The article says that Capella has 2 bright components Aa and Ab but nowhere is their most obvious and relevant attribute - their angular separation - given. The first thing someone looking Capella in a telescope wants to know is, can he expect to see these 2 separate stars. Paulhummerman ( talk) 03:25, 3 December 2020 (UTC)
