The Sun's Brightness[edit]

The sun has an apparent magnitude of -26.74. It should be added to this article that the apparent magnitude of the sun converts to 98,000 lux.

Color[edit]

The sun is white. This is mentioned in the article. But the picture is orange. Can we replace it with a true color picture so as not to perpetuate the myth of an orange sun? — DanielLC 23:59, 10 June 2014 (UTC)

I totally agree. There has been previous discussion about this on the infobox talk page (Template_talk:Solar_System_Infobox/Sun#Replaced_the_false_color_image_of_sun.) and here (Talk:Sun/Archive_6#True_color), but there was no consensus. Maybe this time though. Ulflund (talk) 01:24, 11 June 2014 (UTC)
Moderately agree. We have a source that we cite in the lead [1] saying the Sun is white, so unless there's a WP:RS saying the Sun is some other color, it's white, and so the infobox picture should be white. Furthermore, if you're floating in space and close enough to see it directly as a disk rather than a dot, it'll look white, correct? That said, I don't find the current infobox misleading; I don't know that anyone is really going to think the Sun is (tangerine?) orange and flecked with red and white dots and visible flares like in the current infobox picture, which quite clearly is not the Sun as we see it with our eyes. Rolf H Nelson (talk) 04:36, 12 June 2014 (UTC)
If we end up keeping the current image, we should at least caption it as being an extreme ultraviolet image; it's not obvious to a layman like me what part of the spectrum this is until I click through to the image template file. Rolf H Nelson (talk) 04:40, 12 June 2014 (UTC)
The sun is "white" because the sun defined "white" in your eyes. Does it not depend, where in the sky it is? So at sunset it is defiantly red. In space, it is defiantly too bright to see. Is red really such a bad choice? wouldn't black and white end up looking like the moon (on tv)?DarkShroom (talk) 01:12, 13 July 2014 (UTC)
btw further the sun is actually modelled as a black body, black bodies emit red light as they get up to temperature, they then go yellow and eventually white when your eyes are saturated, so yeah again i like red, especially since it is not something you'll ever look at anyway DarkShroom (talk) 01:21, 13 July 2014 (UTC)

rotational velocity data comment[edit]

Minor point; rotational velocity is listed 7.189×103 km/h (superscript 3 doesn't copy correctly). Altho not much of a concern, takes fewer characters & space, and, more importantly, easier to read/interpret if listed 7,189 km/h. If number was larger then scientific notation would be beneficial. Number is not large so scientific notation not necessary. More legible without. This would also be true for the "Average Density" listing of 1.408×103 kg/m.

Shouldn't list "declination" and "RA"[edit]

I believe that declination and RA are references to where a celestial object appears to be, from earth, on the celestial sphere. (Click on the "declination" link to see what I mean)

The Sun has a declination, though it is continually changing between -23.4 and +23.4 degrees, and it has an RA that is also changing.

Can anyone explain to me why these values are here and what they mean? Dgluss (talk) 23:00, 14 August 2014 (UTC)

I'd like to remove the declination and RA listed in the article, since they are wrong. See [1], for example, for the current correct values.
