Inside the sun image

I can’t see the image fully ~2026-93758-4 (talk) 15:52, 11 February 2026 (UTC)

Do you mean the "Structure" image? Is it cut off somehow? —Antonissimo (talk) 23:49, 12 February 2026 (UTC)

Under the Sun#Formation heading there is the following text. This edit should be made to add a link to a relevant article:

−

The stars [[HD 162826]] and [[HD 186302]] share similarities with the Sun and are hypothesised to be its stellar siblings, formed in the same molecular cloud.

The stars [[HD 162826]] and [[HD 186302]] share similarities with the Sun and are hypothesised to be [[solar sibling]]s, formed in the same molecular cloud as the Sun.

Thanks. However I have chosen a different path: I deleted this content. The specific candidates have been disputed. I think for an article at this level we should focus on more settled science about the Sun. We should update solar siblings as new studies have been published but no review that list confirmed sibling, more like questions if it is even possible to identify them.

Chemical composition

I find it very hard to believe that the sun at present contains more hydrogen and less helium than at the time it was formed. After all it spent a few billion years converting hydrogen into helium See Sun#Composition ~2026-42779-07 (talk) 21:30, 1 August 2026 (UTC)

The article does not give the current composition of the Sun as far as I can tell. Numbers in the first paragraph for H and He are for the photosphere, and near the end the article claims the photosphere composition is near the primordial composition. So that is what leads to your observation.

The end of the first paragraph seems to give composition of the interior but not for H / He. The middle of the section claims changes in composition due to fusion. All around a mess. Johnjbarton (talk) 22:50, 1 August 2026 (UTC)

In the Physical characteristics tab.
Please change the Volume value from 1.412×10¹⁸ km³ to 1.410×10¹⁸ km³.So that it correlated with the existing Equatorial radius value of 695,700 km. ~2026-43091-55 (talk) 23:07, 5 August 2026 (UTC)

Thanks. I added a reference that gives the current value. I also changed the radius value and some temperatures. They were sourced to

• Prša, A., Harmanec, P., Torres, G., Mamajek, E., Asplund, M., Capitaine, N., ... & Stewart, S. G. (2016). Nominal values for selected solar and planetary quantities: IAU 2015 resolution B3. The Astronomical Journal, 152(2), 41.

which has a table with the values and a note: these values should not be considered the true solar/planetary properties. They should be understood as conversion values only. Johnjbarton (talk) 02:26, 6 August 2026 (UTC)

Pronunciation in the Etymology section

In the spoken Wikipedia version of this page, the narrator admitted that they may not be pronouncing the words correctly. Does anyone know how pronounce these correctly in case the author wants to re-record that section? Could anyone make an audio recording of that section being spoken correctly for future reference?
