Under the subtitle "Motion in the Solar System"
There is an unsupported conclusion with an orphan reference. To wit: "[…] The orbits of the inner planets, including of the Earth, are similarly displaced by the same gravitational forces, so the movement of the Sun has little effect on the relative positions of the Earth and the Sun or on solar irradiance on the Earth as a function of time.[140] […]"
Checking footnote 140 reveals:
Retraction of: Scientific Reports 10.1038/s41598-019-45584-3, published online 24 June 2019 The Editors have retracted this Article. After publication, concerns were raised regarding the interpretation of how the Earth-Sun distance changes over time and that some of the assumptions on which analyses presented in the Article are based are incorrect.The analyses presented in the section entitled “Effects of SIM on a temperature in the terrestrial hemispheres” are based on the assumption that the orbits of the Earth and the Sun about the Solar System barycenter are uncorrelated, so that the Earth-Sun distance changes by an amount comparable to the Sun-barycenter distance. Post-publication peer review has shown that this assumption is inaccurate because the motions of the Earth and the Sun are primarily due to Jupiter and the other giant planets, which accelerate the Earth and the Sun in nearly the same direction, and thereby generate highly-correlated motions in the Earth and Sun. Current ephemeris calculations [1,2] show that the Earth-Sun distance varies over a timescale of a few centuries by substantially less than the amount reported in this article. As a result the Editors no longer have confidence in the conclusions presented. S. I. Zharkov agrees with the retraction. V. V. Zharkova, E. Popova, and S. J. Shepherd disagree with the retraction.

The Sun's low lithium level is key to its stable luminosity and low large solar flare events. Yet lithium is not in the page at all. Should be added. [1] [2] [3] [4] — Preceding unsigned comment added by Telecineguy ( talk • contribs) 23:58, 19 February 2024 (UTC)

Can we somehow change the reference named "IAU2015resB3" to not use "cs2" mode, to avoid the article being in the "CS1 maint: overridden setting" maintenance category? Maxim Masiutin ( talk) 20:30, 24 March 2024 (UTC)
The word "than" should be removed from this sentence in Life phases in the Sun page.
The Sun today is roughly halfway through the most stable part of its life. It has not changed dramatically in over four billion years and will remain fairly stable for about than five billion more. Tjkarani ( talk) 20:26, 29 March 2024 (UTC)
When I read the article it reads very much like someone stood on the Sun and was able to do actual measurements, even though the constitution of the Sun is fairly unknown. People once believed it was a burning ball of fire, but if that were true, it would have died out really quickly, because there's no oxygen. That explains to some extent the move to nuclear fusion, but one might argue that nuclear fusion actually costs energy rather than produce it.
A viable alternative that was once brought to my attention was that the Sun is made out of an inert gas, most probably Radon. It was brought to my attention, but I have no references, sorry. The reason this explanation is so viable is as follows:
The Sun when it's a highly abrasive solvent with near perfect light absorbing and emitting qualities expends very little energy on itself and replenishes really quickly with matter and light hitting it. The Sun itself as such is very cold, because almost all of the energy it receives as matter or light is sent back out again as light into the Universe, of which only a small portion reaches the Earth, but that small portion by itself is thus big that it can heat us sufficiently.
The formation of stars out of gases provides a good first step for corroborating this theory, because in space inert gases can actually liquify and maybe even solidify due to the extreme coldness of space. Essentially the Sun isn't much different from a tube or bulb of inert gas, but without the glass container around it, and under its own gravity it's probably a lot more dense than gas in a tube or bulb.

I feel like an FAR may be needed. This article contains unsourced text and there is a better source needed tag. The lede would also stylistically look better if the second and third paragraphs were about the size of the current fourth paragraph, but that isn't a requirement. 750 h+ 15:03, 2 May 2024 (UTC)
Reading the topic "FAR" (which I believe is wiki-speak for "Featured article review") I saw the article has a "better source needed" tag. I thought I could make a quick fix.
Surprise! The tag concerns a retracted article on Solar motion relative to the solar barycenter (center of mass for solar system). The article failed to account for correlated motions of the planets and thus incorrectly connected the Sun's motion to Sun-Earth motion.
So easy fix: find a different source? Oh, it turns out that one of the leading theories of the cycles of Sun spots relates to the Sun's motion relative to the barycenter, and that in turn relates to climate change. Consequently you can find lots of refs with lots of different stories. I guess that may explain why the paper was officially retracted rather than say publishing a correction.
For this reason I am changing the paragraph to include content based solely on the 1964 paper by Paul Jose. Johnjbarton ( talk) 15:36, 8 May 2024 (UTC)
The intro currently says
but this is not in the article as far as I can tell. The closest thing I found was:
which would mean the intro should say "all as visible light, ultraviolet, and infrared radiation." Which is equivalent to "mainly as pretty much anything". Johnjbarton ( talk) 02:52, 22 May 2024 (UTC)
