List of star systems within 500-550 light-years nominated for deletion
edit@ Wikipedia:Articles for deletion/List of star systems within 500-550 light-years ~ Tom.Reding (talk ⋅dgaf) 15:10, 21 August 2024 (UTC)
- It's not surprising that the lists of nearby star systems has kept expanding, because where do you cut them off? Praemonitus (talk) 15:38, 21 August 2024 (UTC)
- It looks like the cut-off is now 500 light years, with the outermost being List of star systems within 450–500 light-years. The outer lists are fairly short, so we could even merge the ones from 100 to 500 ly. But it's probably not worth the bother. Praemonitus (talk) 22:04, 9 September 2024 (UTC)
- I agree. Also, not bothering gives more room for expansion. ~ Tom.Reding (talk ⋅dgaf) 12:17, 10 September 2024 (UTC)

A formal RfC against Universe Guide
editSo for context, I first noticed this questionable source regarding Theta Muscae, which I then reached out at WT:ASTRO for a note, and made me realize this source has been cited in multiple existing articles and is a worse problem than I thought. A past discussion on the RSN confirms this as an unreliable source and a personal blog website of N. John Whitworth, who has superficial background in astronomy, if at all (as one can see upon the poor grammar and science fiction-like writing of the site). However, that particular discussion was quite unfruitful and did not follow the proper method on launching an RfC investigation that should have classified this as a deprecated source and discouraged its use on Wikipedia.
This time, however, I wanted to launch a formal RfC against this website. It is very popular and appears mostly on the top of Google searches, so it would be inevitable that time and time again this farce blog will be used as a source for astronomy articles. I however did not have the tools to look for articles on where this website was used as a source and make a more solid complaint, as I believe 40 articles is an underestimation. I also don't know much about the history of how this website had been cited, so if anybody out there has the technical skills to outline this, maybe you can help out. It would be greatly appreciated.
That's all. I am having quite a bad day right now after staying all night, and I became more mad upon looking at this website's entries. SkyFlubbler (talk) 00:07, 29 August 2024 (UTC)
- @SkyFlubbler: Why not do this at RSN? –LaundryPizza03 (dc̄) 02:07, 29 August 2024 (UTC)
- Special:LinkSearch may be helpful. Yes, this is clearly an unreliable source and shouldn't be cited. SevenSpheres (talk) 02:39, 29 August 2024 (UTC)
- Hey, this is exactly what I was looking for, thank you. I think I'll be writing one now. I'll go back here once it's finished. SkyFlubbler (talk) 05:01, 29 August 2024 (UTC)
- 100% not a reliable source. Please do file for it to be "officially" listed as such. There are a few other such bad sources used on some pages; I've listed some of them on here in the past. I don't think any of those had as wide a use as this one though. - Parejkoj (talk) 18:55, 30 August 2024 (UTC)
- I agree that it is an unreliable source, full of inconsistencies and wrong data. 21 Andromedae (talk) 00:34, 31 August 2024 (UTC)
- Agreed here also. Universe Guide is just an amateur site, in all senses of the word. Skeptic2 (talk) 09:32, 31 August 2024 (UTC)
- There's a claim in Saturn, a Featured article, which is cited to "Universe Guide". It needs at least a better source and perhaps a rewrite. See the opening line of Saturn#Atmosphere. Most of the other occurrences seem to be in less prominent places; they all ought to be fixed eventually, but this one sticks out in particular. I'd be concerned that any website source since 2009 could have just copied that claim from here, and I haven't yet had time to sift the literature for more trustworthy numbers.

Astronomical units
editIf you have any opinions about whether AU should be converted to SI units, please join the discussion at Wikipedia talk:Manual of Style/Dates and numbers#Astronomical units. (To keep the discussion in one place, please don't reply below). -- Beland (talk) 19:10, 6 September 2024 (UTC)
Requested move at Talk:Artemis 1#Requested move 4 September 2024
editThere is a requested move discussion at Talk:Artemis 1#Requested move 4 September 2024 that may be of interest to members of this WikiProject. RodRabelo7 (talk) 02:52, 12 September 2024 (UTC)
Radius calculation discussion
editThere is a discussion about NML Cygni and how to best calculate its radius. Please join in the conversation at Talk:List of largest stars § NML Cygni. Primefac (talk) 12:17, 17 September 2024 (UTC)
Moon discussion
edit- There is a discussion at Talk:Moon#External links that editors might be interested in joining. Otr500 (talk) 21:36, 1 October 2024 (UTC)
Merging Theia (planet) into Giant impact hypothesis
editI have proposed merging Theia (planet) into Giant impact hypothesis, see Talk:Giant-impact_hypothesis#Proposal_to_merge_Theia_(planet)_into_this_article. Participate if interested. Thanks. Hemiauchenia (talk) 03:02, 6 October 2024 (UTC)
Wikidata and Right ascension and Declination properties and Redshift
editI noticed that on WikiData, you cannot add sexagesimal hour/degree or decimal hour values to the property fields for right ascension (wikidata:property:P6257) and declination (wikidata:property:P6258).
And for redshift (wikidata:property:P1090), it should be available to specify units of "z=v/c" for unitless z-values, to distinguish it from redshifts given in km/s.
Does anyone know how to modify wikidata to do that?

- Did you try asking at the WikiData community portal? Praemonitus (talk) 04:51, 19 October 2024 (UTC)
Rename Radiation zone -> Radiative zone
editPlease see Talk:Radiation_zone#Renaming_to_Radiative_zone. and Wikipedia:Requested_moves/Technical_requests#Uncontroversial_technical_requests. Johnjbarton (talk) 22:28, 19 October 2024 (UTC)
- Because "radiation zone" has many hits on Google Scholar (for Van Allen belt), I have to do this instead: Talk:Radiation_zone#Requested_move_19_October_2024. Johnjbarton (talk) 23:57, 19 October 2024 (UTC)
The article HD 185435 has been proposed for deletion because of the following concern:
not notable per WP:NASTRO
While all constructive contributions to Wikipedia are appreciated, pages may be deleted for any of several reasons.
You may prevent the proposed deletion by removing the {{proposed deletion/dated}}
notice, but please explain why in your edit summary or on the article's talk page.
Please consider improving the page to address the issues raised. Removing {{proposed deletion/dated}}
will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion. Loooke (talk) 02:32, 27 October 2024 (UTC)
Interacting_galaxy#Notable_examples needs revising
editThe "Notes" column makes reference to the "first/second/third phase" of galactic collision, but has no additional information or citations as to what exactly defines each "phase". On top of that, the "Notes" section for NGC 2936 just contains a single question mark, and has been that way for over 6 years now. The section would also benefit from more examples of non-merger interactions, such as tidal distortion (e.g. NGC 6872), ram pressure stripping (e.g. Comet Galaxy and NGC 4402). The page in general should probably also make note of Ring galaxy formation via collision.
I'd make the necessary changes myself, but I don't know where or how to find citations, and the revision process itself would also likely be a rather large undertaking for a lone newbie editor like me, and I don't really have the spare time right now to fully dedicate myself to this.
