Better picture?

The first non-infobox photo in this article ("The Sun, as seen from the Earth's surface") is actually... not great quality? Should we add a picture taken with a better camera? Or maybe I'm just underestimating how hard it is to take a good photo of something as bright as the Sun. Alex Martin ( talk) 04:23, 23 June 2021 (UTC)

I think the current photo is fine, but maybe I'm misunderstanding your proposal. Are saying that it should be replaced with a higher quality, almost identical photo or an entirely different one? If it's the latter, doesn't the current photo depict how the sun looks to the naked eye and is therefore important that it stays? CoronalMassAffection ( talk) 18:44, 27 June 2021 (UTC)
The current image has a lot of lens flare that makes it look... I guess "blotchy" is the best word. I'm not sure how one would actually go about improving it, though, so maybe it should just be left. Alex Martin ( talk) 22:01, 29 June 2021 (UTC)

Why use "visible brightness" instead of "apparent magnitude"?

The article's sidebar says: Visual brightness (V) −26.74[5]

On WP for other stars the term apparent magnitude is frequently (perhaps exclusively?) used, and clicking on the "Visual brightness" in the sidebar brings you to the apparent magnitude article. Also, the term "visual brightness" doesn't appear in the apparent magnitude article. And finally, Google says the term "absolute magnitude of the sun" appears 78,000 times on the web, but the term "visual brightness of the sun" appears only ten times. Perhaps the term in the sidebar could be changed to apparent magnitude? Bob Enyart, Denver KGOV radio host ( talk) 15:37, 20 August 2021 (UTC)

Removed chart of terrestrial irradiation

Hello! I've removed a misleading chart with commit. The main problem is that it shows irradiance levels of what the Earth receives per m³ (minus atmospheric absorption), and not what is emitted from the surface of the Sun, which should be the topic. (The supplementary text was nice, however.) It would be nice to have a chart that shows actual radiation values at the source (63MW/m³ I think?) with both black body values and actual, showing the Sun's own absorption lines. Daniel Santos ( talk) 14:55, 29 August 2021 (UTC)

The chart that you've removed shows the solar irradiance at a distance of 1 AU and does not include atmospheric absorption. It shows the spectrum that is emitted from the sun without other factors. This convention is quite common as these values can actually be measured while the emission of the sun at the surface cannot. That can only be hypothesized.
In any case, you can make an other chart with the data you want to show. But until that is done the perfectly serviceable chart should stay up. Kardoen ( talk) 17:10, 29 August 2021 (UTC)

Formation prose structure

I’ve noticed that a lot of highly technical and detailed science articles write origins sections backwards for some reason, when the reader expects them in chronological order. For example, we don’t find out that the Sun was likely formed from the remnants of a supernova until the end, instead of explaining this at the beginning. I’ve seen this kind of thing in many different articles and I’ve never understood why people write like this. Wouldn’t it make more sense and clear up a great deal of confusion and facilitate understanding and comprehension by reversing the chronological narrative structure of the paragraph? Viriditas ( talk) 23:03, 22 May 2022 (UTC)

I'm not sure I understand the issue here. Supernovae (as an original source of the Sun) are mentioned in the second named section "General characteristics", and then in the first sub-section of the "Life phases" section. How much earlier do you want it mentioned? The "Life phases" section is admittedly halfway down the article, but I don't see a problem with explaining in detail what the sun is, looks like, etc., before describing how it got to this point. The lead only very briefly refers to the formation of the Sun, and nothing about supernovae, but it seems proportionate. It is also not entirely accurate to say that the Sun forms "from the remnants of a supernova". Supernovae are known/speculated to be the triggers of star formation, but not necessarily *all* star formation, and it is likely that only a few percent of the Sun's material originated in an earlier supernova explosion. The Sun is/was mostly hydrogen and helium, which are mostly primordial. Only the heavier elements are likely from supernovae, and even a fair proportion of those from other sources, and these make up less than 2% of the Sun by mass. It is unclear within an order of magnitude just how much of the hydrogen and helium has previously been part of a star, much less ejected from a supernova. Or maybe I've completely missed the point and you're referring to some other paragraph and only tangentially to supernovae? Lithopsian ( talk) 10:46, 23 May 2022 (UTC)
@ Lithopsian: I thought the section heading would explain it, but apparently that didn’t work. I’m only talking about the Sun#Formation section. Viriditas ( talk) 20:47, 23 May 2022 (UTC)
The kind of "reverse" origin section is an accident of ease of inquiry. The problem is that it is always easier to reconstruct events in the past that happened closer to the present. Couple this with the problem of infinite regress and you end up with a conundrum for those trying to explain concepts that often results in this kind of preference for picking a series of origin points that go backwards in time as though answering the questions from the five-year-old about, "Yeah, but where did that come from?" In general, the Sun is described as originating from the presolar nebula in most standard accounts. Where the nebula came from is a great question, but is one that doesn't have nearly as clear an explanation and so the vague evidence about "a few supernovae" that provided the metallic content and shockwave physics is definitely something that people who are interested in explaining "origins" of the Sun will add as an afterthought. Sorry that I can't be more helpful than this. It would be great if we could start every article from the Big Bang and move forward, but I think in practice the reverse lookback approach is often a more stable way to present what we know with greater certainty. jps ( talk) 11:42, 23 May 2022 (UTC)

"Heated to incandescence"

I think "heated to incandescence" is redundant, since the same sentence already mentions hot plasma. Can a hot plasma be "heated to incandescence"? Perhaps "to incandescence" should be dropped so that the sentence would be "It is a nearly perfect ball of hot plasma, heated by nuclear fusion..." Brandmeister talk 14:44, 27 September 2022 (UTC)

While the properties of plasma are familiar to you and I, a good chunk of the readers of this page won’t have the same knowledge and will probably benefit from having the “heated to incandescence” line. I support its continued inclusion. Marchantiophyta ( talk) 17:50, 30 September 2022 (UTC)

How can this have a black body spectrum? Oscar Blauman 16:04, 30 September 2022 (UTC) — Preceding unsigned comment added by Omblauman ( talkcontribs) Furthermore: "The photosphere is tens to hundreds of kilometers thick, and is slightly less opaque than air on Earth." How a BB can be less opaque than something else? — Preceding unsigned comment added by Omblauman ( talkcontribs) 16:07, 30 September 2022 (UTC)

I'm not sure what all your complaints are, but the question about opacity of a black body, I can answer. The Sun, as a whole, approximates a black body. A thin slice of relatively transparent atmosphere is not itself a black body, although enough of it together could be (assuming enough variation that it is not entirely transparent at soem wavelength). Generally, black bodies are the sum of many interactions which results in all incoming radiation being absorbed (rather than reflected). Conversely, this black body emits radiation based on its temperature. Going beyond this requires diving into statistical mechanics. Tarl N. ( discuss) 23:14, 30 September 2022 (UTC)

Name

The Sun has several alternative names listed in English. However, none of the alternatives are commonly recognized names for the Sun itself and instead refer to Greek and Roman deities.

Correction...

Every second, the Sun's core fuses about 600 million tons of hydrogen into helium, and in the process converts 4 million tons of matter into energy.

This should read 620 million.. The nuclear fission page has it updated already.

Power density of the sun myth perpetuated here

"The large power output of the Sun is mainly due to the huge size and density of its core (compared to Earth and objects on Earth), with only a fairly small amount of power being generated per cubic metre. Theoretical models of the Sun's interior indicate a maximum power density, or energy production, of approximately 276.5 watts per cubic metre at the center of the core, which is about the same power density inside a compost pile."'

This is wrong. The cited source is some abc austrailia blog.. This is the power density of the entire sun, NOT the core. Fusion only takes place in the core.

No, the power density at the extreme center of the core is ~280 W/m^3. It is much lower than that when averaged over the entire sun's volume. VQuakr ( talk) 22:01, 21 November 2022 (UTC)

History of spectroscopy of stars

I miss info about history how these things were discovered and/or developed. I tried to find more, and found info about close to current affairs, but most articles about EM spectrum, spectroscopy etc. lack a section about history, and where I saw it, it was more superficial than not.

Some might say that that is not notable, but if we need, and want, next generations of passionate researchers, they need, preferably as children, to be able to see how we got to the current level of knowledge, not only how to find useful data in WP.

Marjan Tomki SI, then let's ignore all rules and make it happen! CactiStaccingCrane ( talk) 07:13, 8 January 2023 (UTC)
The problem is sources...
Several (at least 4) decades ago I encountered several books, in my native Slovenian language that influenced me massively on areas of chemistry and biology (and with some others to science in general).
A generation later a niece of mine read the same 4 books from my bookshelf, and it went on through teachers training for biology and chemistry, and university study and graduation in biology, through masters and PhD in moleculary genetics, to what she is working on now. And she was through her studies, and is now an excellent source for current state of science in that area for mne (but not published and peer reviewed I can cite, so not valid as WP verifiable).
I can still recall (and retell) most of the contents of most of those books (and from time to time do that in suitable chunks to interested audience of junior generations, in which case I check the up-to-date validity of the facts the story is about if I can, or we do that check together).
As far as I recall we found those facts still valid, even if in some cases a bit incomplete. But that checking and taking conclusions would be probably taken as original research by WP (unless we would search, and took notes about that, for literal citations for them - which children and also most adults would find boring, and that would kill their interest instead of enticing it. (Being rigorous about sources is a pretty much later step - usually when they ask where I know something from I can introduce both checking and looking for sources, and requiring them being as rigorous with it as they require it from me, and same rules for everybody usually get easily accepted by most).
On biology those books were a series of Paul de Cruifs that can still be found, and cited; on chemistry it was a book (supposedly translated in Slovenian from Russian) Stories about Elements (Povesti o Elementih, in Slovenian) of Nechayew (Nečajev in Slovenian, probably Нечаев in Russian). Problem is that I couldn't find any mention of the author or his book in any language but that edition in Slovenian. My copy from those years back was read by a lot of people and didn't return (yet). I found another copy for my niece (the one mentioned above) for her son in Germany (to have something to read to both keep him used to her native language and get interested in chemistry), so currently don't have a Slovenian copy at hand.
So at the moment I can't add citations to the source for the stories I needed when young, if I retell them. Do we dare to ignore that WP rule? Marjan Tomki SI ( talk) 09:16, 21 January 2023 (UTC)

There are multiple typos on this page.

There are multiple typos within this page, even if it is a featured page. I will list all of them.

- Under heading 'Composition' there is text on the 3rd - 4th line of the 4th paragraph that reads as follows: 'The proportions of heavier elements is unchanged.' This is incorrect, it should be: 'The proportions of heavier elements ARE unchanged.'

- Under heading 'Solar activity', which is, in turn, under 'Magnetic activity', the 3rd - 4th line of the 1st paragraph states: 'Both coronal-mass ejections and high-speed streams of solar wind carry plasma and interplanetary magnetic field outward into the Solar System.' It should be 'Both coronal-mass ejections and high-speed streams of solar wind carry plasma and THE interplanetary magnetic field outward into the Solar System.'

- Under heading 'Celestial neighbourhood', which, in turn, is under 'Motion and location', there are examples of which both British English and American English are used in the same context. These are:

  • The title: 'Celestial NEIGHBOURHOOD' as an example of British English
  • On the 1st - 2nd line of the 2nd paragraph, the sentence ' The Local Bubble is a small superbubble compared to the NEIGHBOURING wider Radcliffe Wave and Split linear structures (formerly Gould Belt), each of which are some thousands of light-years in length.' is an example of British English
  • In the same paragraph, in lines 4 - 5, we get 'The density of all matter in the local NEIGHBORHOOD is 0.097±0.013 M☉·pc−3.' This is an example of American English.

- Under heading 'Solar space missions', which is, in turn, under 'Observational history' states, in the 1st line of the 4th paragraph: 'In 1980, the Solar Maximum Mission probes WAS launched by NASA.' This should be changed to 'In 1980, the Solar Maximum Mission probes WERE launched by NASA.', as probes is a plural, and requires a plural verb (in this case, 'were') for the sentence to make sense grammatically.

- Under the same heading, 'Solar space missions', when talking about the Solar Terrestrial Relations Observatory (STEREO) mission in paragraph 9, in lines 1 - 3, the following sentence is stated: 'Two identical spacecraft were launched into orbits that CAUSE them to (respectively) pull further ahead of and fall gradually behind Earth.' This should be 'Two identical spacecraft were launched into orbits that CAUSED them to (respectively) pull further ahead of and fall gradually behind Earth.', as the beginning of the sentence clearly stated that this had already happened with the use of the word 'launched' in past tense, all verbs in the sentence should also be in past tense, therefore, 'CAUSE' should become 'CAUSED'.

- Under heading 'Religious aspects', in the last line of the 3rd paragraph, the text reads: 'In the form of the sun disc Aten, the Sun had a brief resurgence during the Amarna Period when it again became the preeminent, if not only, divinity for the Pharaoh Akhenaton.' 'Akhenaton' is a straight up typo, and should be replaced with 'Akhenaten' as even it's Wikipedia page spells it like this.

Some of the changes had to be made over at Solar System (since some of the issues you referenced were transcluded from that page), which was not unified in its English variation and hadn't been at any point since its creation back in 2001 - there was a fair amount of work figuring out the correct variation for that article and unifying it appropriately.

Dwarf Star

The article suggests that the Sun is incorrectly called a dwarf star. This is not the case, the Sun IS a dwarf star.

Yes, the Sun is a dwarf star. I think the uncertainty implied in the article with "As such, it is informally, and not completely accurately, referred to as a yellow dwarf (its light is actually white)" is about its colour, not about whether it is a dwarf. The article is trying to say that the Sun is often called a yellow star, even though it is white. That you misread this as meaning the Sun may not be a dwarf star shows an ambiguity in the text.

Picture of the Sun

Concerning the picture of the Sun. Why is the light intensity of the Sun graduated (less intense at the periphery)? Normally, projection of a lighted ball will have the same light intensity all over the projection. Henrikoesterbro ( talk) 13:01, 24 July 2023 (UTC)

atmosphere of the sun -- temperature

We can read: The average temperature of the corona and solar wind is about 1,000,000–2,000,000 K; however, in the hottest regions it is 8,000,000–20,000,000 K. source 81 the source doesn't confirm. Hard to find sources but at most it would be 5 millions K???? please confirm Chanterel G ( talk) 02:12, 31 August 2023 (UTC)

Center Density

How can 162.2 g/cm³ be 12.4× Earth while Earth is at mean 5.513 and even if we use a molten iron core of 7.87 we get a factor of 30. 2A01:C23:855F:3900:D975:C91E:BCDA:F14F ( talk) 16:33, 16 September 2023 (UTC)

First sentence

Hi there, I get the argument about "keep it simple", but how about the following, because I find it important to spell things out as much as possible for people who have no clue about astronomy:

"The Sun is a star and the center which Earth and all of the Solar System moves around."

What do you think? Nsae Comp ( talk) 01:15, 7 October 2023 (UTC)

It doesnt need to be this sentence, I just see the need to mention Earth right away to put the Sun easily into relation. Nsae Comp ( talk) 07:06, 7 October 2023 (UTC)
Earth is already specifically singled-out and adequately mentioned in the first paragraph, no need to repeat it in the first sentence. The Sun's relationship with Earth is understood and described with the existing language in the third sentence. Randy Kryn ( talk) 10:49, 7 October 2023 (UTC)
For ease to follow the discussion, here my last proposal that was taken out now. I liked it for being concise.

"The Sun is the star at the center of the Solar System, with Earth as one of its orbiting planets."

... who knows maybe someone else can do something that suits everyone. Nsae Comp ( talk) 13:18, 7 October 2023 (UTC)
Getting close. I think we should stick with the opening clause "The Sun is the star at the center of the Solar System", and I think a second clause would be useful, but "with Earth as one of its orbiting planets" is both too specific (singling out Earth) and too vague ("...one of its orbiting planets"). How about "...around which the Earth and other planets orbit"? Obviously there is more than planets, but the original "all of the Solar System" didn't sit well and I can't think of something succinct enough to be in the opening sentence and clear enough to cover everything in the Solar System. After all, the article is about the Sun and cluttering up the opening sentence with details of something else (ie. the Solar System) is a great idea). Perhaps better to relegate that idea to a later sentence that could be more complete, leaving the opening sentence very simply describing the Sun? Lithopsian ( talk) 14:19, 8 October 2023 (UTC)
"The Sun is the star at the center of the Solar System" seems enough. 'Solar System' already covers the planets, the moons, the asteroids, comets and other riff raff (wondering if a giant star's planetary system includes periodic comets as big as Earth). Randy Kryn ( talk) 22:54, 8 October 2023 (UTC)
...here one more possibility; only because I just thought of this version:
"The Sun is the star at the center of our planetary system." ;) Nsae Comp ( talk) 06:25, 12 October 2023 (UTC)
See MOS:OUR, and the Sun anchors the named Solar System, not a planetary system which is a term used for other stars outside of the Solar System. Randy Kryn ( talk) 13:18, 12 October 2023 (UTC)

NASA data

User:Randy Kryn, personally I think that this table at Sun#General_characteristics should be removed mainly because it is essentially another infobox but in the body, which increase maintenance cost for future editors; we already have much more precise and comprehensive information in the infobox cited to reliable sources (even for occasional comparison with Earth's statistics). I have a feeling that you want to make the infobox less long by offloading some of the statistics to a dedicated table, and to be honest that's a pretty good idea that we should discuss further here.

In the edit summary you said that "infobox does not preclude the same information appearing in the text, and most infobox information usually appears in the text", but in Wikipedia:Manual of Style/Infoboxes, it is explicitly said that "As with any guideline, there will be exceptions where a piece of key specialised information is difficult to integrate into the body text, but where that information may be placed in the infobox." CactiStaccingCrane ( talk) 16:03, 8 January 2024 (UTC)

Hello CactiStaccingCrane. The chart in the text seems a good addition which was added almost six months ago. I didn't focus on the length of the infobox but yes, it does come across as too large. Randy Kryn ( talk) 16:12, 8 January 2024 (UTC)
Could you clarify why you think it is a good addition, when we already have the infobox for the same statistics? CactiStaccingCrane ( talk) 16:14, 8 January 2024 (UTC)
They are laid out better in the chart for the average reader, making the stats more understandable. Information in an infobox does not preclude it from being included in the text, and entries in infoboxes are usually repeated in the text, in most case within the lead or close to it. Randy Kryn ( talk) 16:21, 8 January 2024 (UTC)
I'm with Cacti on this one, I see no good reason for this duplication. Artem.G ( talk) 17:03, 8 January 2024 (UTC)
Adding my $0.02 - I don't think that particular table contributes much. A table of physical characteristics is useful, but if it's in the infobox already, we don't need another. Perhaps we could shorten the infobox (which is pretty cramped), and move some of the data into a table. But this particular table, giving comparison with earth sizes, is something I find uninteresting. The fact that it's a direct copy of a NASA document also leaves me uneasy - copyright isn't an issue, but even so, a direct copy is not quite what I'd like to see on Wikipedia. Tarl N. ( discuss) 19:40, 8 January 2024 (UTC)
I'd also be in favor of deleting that table. I don't think it adds any essential new content to the page. Also, the table title is "comparison between sun and earth" but it lists a bunch of solar properties that have no earth analog, like spectral type G2V, or luminosity, where it doesn't make sense to have any comparison at all. And some quantities like "visual magnitude" make no sense for Earth without additional context (like what distance you're assuming you are observing the earth from, or that sort of thing). Aldebarium ( talk) 20:05, 8 January 2024 (UTC)
Agree with the proposed removal. Nikkimaria ( talk) 00:12, 9 January 2024 (UTC)

I am gonna go ahead and remove the table. CactiStaccingCrane ( talk) 01:32, 10 January 2024 (UTC)

CactiStaccingCrane, you don't give discussions much time do you? In my experience that's not how it works on Wikipedia, but not going to make a fuss about it since it seems the way this one would probably ('probably', not 'certainly') turn out. Randy Kryn ( talk) 04:13, 10 January 2024 (UTC)
Randy Kryn, no, it's not that I want to do things my own way, but because the problem is blindly obvious and you did not give a detailed explanation about your reasoning. You could extend this thread and challenge my actions if you wish, but I am afraid that without a good explanation from your side, it will not be successful.

Gravity waves

The article mentions "gravitational waves" - this almost certainly is wrong. Gravity waves are hydrodynamic surface waves while gravitational waves relate to general relativity. Turns out words matter. (I saw gravitational waves mentioned here as a cause of coronal temperature, and clearly the effects of GR under that gravitational regime are negligible.) 98.21.213.85 ( talk) 16:04, 28 January 2024 (UTC)
