Wikipedia:Articles for deletion/List of minor planets: 500001–501000


 * The following discussion is an archived debate of the proposed deletion of the article below. Please do not modify it. Subsequent comments should be made on the appropriate discussion page (such as the article's talk page or in a deletion review).  No further edits should be made to this page.

The result was keep. Keep with respect to "List of" articles. Some copyright concerns were raised, but I'm not sufficiently convinced to speedy delete at this point - as Justlettersandnumbers states, the data we're reproducing is primarily simple facts from a government database, so even if the California Institute of Technology claims copyright over the design of their webpages, the data from NASA JPL seems like it should be PD. As Rfassbind and Dlthewave state, I'd encourage contributors to start a focused discussion perhaps at WP:CCI or one of the talk pages for more focused investigation (and please ping me if you do, as I'm interested).

No consensus with respect to "Meanings of" articles. If the nominator still wishes for those to be deleted, I'd recommend they create a new AfD, as there is some support here to delete them or merge them. Due to the combined nomination here, they may not have gotten the full attention of the participants in this debate. ST47 (talk) 14:54, 1 July 2019 (UTC)

List of minor planets: 500001–501000

 * – ( View AfD View log  Stats )

List of minor planets seems to be an attempt to build a database of all 500,000+ minor planets that have been discovered to date. The first few thousand have individual names and even Wikipedia articles in some cases, but everything past about 100,000 is nothing more than a list of numbered entries accompanied by a completely empty "meanings of names" list. They show no sign of notability or significance, neither individually nor collectively

There are over 400 pages that fit this description so I just picked the first 10 in the 500,000 series as a starting point.

Also of concern is the fact that each page is a near-exact copy of data from the Minor Planet Center, which raises potential copyright issues. –dlthewave ☎ 18:11, 23 June 2019 (UTC)

 * Comment Jesus lord I had no idea someone had made something like this on Wikipedia. I appreciate their effort but I have to agree with the nominator and agree that there seems to be a lack of notability for a lot of these.★Trekker (talk) 19:23, 23 June 2019 (UTC)


 * Speedy delete the Meanings of Names articles. Massive WP:TROUT to the irresponsible person who mass-created scores of literally empty articles that couldn't even be theoretically filled since these have only numeric names. Delete other lower-numbered Meanings of Names articles that do have some namesakes, which are copied directly from the respective citations already provided in the main lists. Perhaps the main lists could have a column for 'Named after', but we do not need to have articles just to copy and paste the primary source for something not covered by tertiary sources; the Citation column links to the meanings page through a repetition of the name, but it's unclear what warrants the duplication or what makes this a citation – both have the same JPL link in the Ref column. Weak keep the main planet lists: Yes there's a lot of them but I believe these were a compromise as a way to cover scientific information without having articles on individual asteroids, though there are still quite a few of them e.g. 4585 Ainonai that are certainly not notable, all sources being databases of stats without WP:SIGCOV. These should be redirected to the lists with linked citations. Reywas92Talk 19:24, 23 June 2019 (UTC)


 * Merge or Redirect the Meanings of minor planet names pages. Maybe we could merge all these pages into a parent Meanings of minor planet names: 500,001–600,000 page. (That sounds like a lot of work, but maybe it could be automated somehow?) The meanings of pages past 500 000 are indeed particularly sparse (note that as of May 2019, there are only 21922 named minor planets), but the occasional one does show up (e.g. 510045 Vincematteo). Supposedly the number of named minor planets is growing at a rate of about 670 namings per year, but we can always WP:SPLIT later if necessary. Keep the List of minor planet pages. This AfD for the list of minor planets page is a bit old, but I think it establishes that the concept of a list of minor planets is notable. WP:LSC suggests that it is acceptable for certain types of lists (e.g. all known species within a taxonomic family) to be exhaustive. I'd argue that a list of minor planets also falls under that category. I think the list of minor planets page was only split into subpages to keep the page sizes manageable, so the overarching notability of the list as a whole should still be applicable to these subpages, in my view. Per Copyright in lists, I don't think there's any copyright concern. Facts aren't copyrightable, and the minor planet data being listed here doesn't particularly involve any creativity in selection or arrangement. Ahiijny (talk) 20:41, 23 June 2019 (UTC)


 * Keep the List of minor planets This is something you'd expect to find in an Encyclopedia that isn't limited by space.  Keep the others also for reasons others have pointed out.   D r e a m Focus  22:59, 23 June 2019 (UTC)
 * I'm commenting only in the capacity of an AST member who has seen this discussion before.


 * I've transcluded it here since it's relevant to the overall discussion of keeping or deleting these. Primefac (talk) 01:07, 24 June 2019 (UTC)


 * Keep, the list of minor planets contains 541,128 objects in 542 partial lists. About 3,200 articles of notable objects are linked from, and about 23,500 non-notable objects are redirected to this catalog. It is neither sensible to propose the deletion of one (or 10) page(s) from a 542-page catalog, creating a gap in an otherwise complete list, nor is it correct to assert that objects above #100,000 have no notability or significance (just see object, for example). Currently, the highest numbered minor-planet articles are (named) and  (unnamed), while the highest numbered minor-planet redirects are  (named) and  (unnamed). The list of minor planets exists in 48 languages on Wikipedia including the French, Spanish and Italian versions – there is no copyright issue, as the data provided by the MPC and JPL are freely available. Also the list of minor planet meanings goes along with the catalog pages (toggling between the two lists). While there is currently no named minor planet in range 500,001–510,000, this will likely change in the near future. Deleting/merging pages would cause inconsistencies now, and numerous amendments in (re-)creating/splitting pages later on.   R fassbind  – talk  03:34, 24 June 2019 (UTC)
 * Delete per WP:NOTDIRECTORY. I have absolutely no problem with creating a list for some of the more notable minor planets, possibly the named minor planets, but this is not encyclopaedic as it stands. SportingFlyer  T · C  08:11, 24 June 2019 (UTC)
 * Keep Such lists are notable per WP:LISTN; for example, see Dictionary of Minor Planet Names, Volume 1. Our policies WP:NOTPAPER, WP:ATD and WP:PRESERVE clearly indicate that deletion is not appropriate.  The specific guideline WP:DWMP expects these lists to exist as an alternative to lots of separate pages about each minor planet.  I'm not sure why the lists of meanings have not been merged with the main lists but am content to leave such implementation decisions to the people doing the actual work. Andrew D. (talk) 09:43, 24 June 2019 (UTC)
 * Keep Nominator hasn't provided any direct wikipedia policies against this information, the concern over copyright doesn't really apply either as Minor Planet Center is a public released database via NASA and other Non-profit agencies. You could argue that  mathematical significance applies here, as you can use the data to calculate other possible uses in the data. This would make the argument of WP:NOTDIRECTORY void in many respects. I hardly see GNG or LISTN any point to the information here either. It seems we have probably been through this path before and Andrew Davidson has pointed to WP:DWMP which would suggest that this AfD would be invalid next to previous discussed policy. I see no other reasoning not the keep the articles, and keep the chain. Govvy (talk) 10:31, 24 June 2019 (UTC)
 * Strong KEEP all per above - notable per WP:LISTN. Per above, "Our policies WP:NOTPAPER, WP:ATD and WP:PRESERVE clearly indicate that deletion is not appropriate." Also, no copyright issue - the MPC and JPL archives are readily available (and they're non-profit organizations like NASA). Paintspot Infez (talk) 11:49, 24 June 2019 (UTC)
 * Comment (nom) - Although the Minor Planet data has been "publicly released" and is "freely available", this does not mean that it is in the public domain or meets Wikipedia's specific copyright requirements. Just because it's published it on the Internet doesn't mean we can copy it. Both JPL and IAU  make copyright claims for data hosted on their sites. There's certainly a grey area regarding the copyrightability of raw facts and data, but please be aware that the MP data has not been released for unrestricted copying, reuse, etc. –dlthewave ☎ 12:20, 24 June 2019 (UTC)
 * There is no copyright issue here. If you wish to argue that point there is a noticeboard to discuss such things with those familiar with copyright law.   D r e a m Focus  15:18, 24 June 2019 (UTC)
 * No, copyright's definitely an issue based only on a cursory review of the sites dlthewave has linked, and I know dlthewave to be knowledgeable about these matters. Both sites claim that the information isn't in the public domain and that permission is required to republish it, though the NASA dataset use may be acceptable if we link to it. In short, these databases aren't in the public domain, there's a colourable argument we could use some of the data, but if this is kept, we absolutely should take this to the copyvio noticeboard. Anyone claiming copyright isn't an issue here is definitively incorrect. SportingFlyer  T · C  19:03, 24 June 2019 (UTC)
 * Copyright isn't created by ipse dixit. If the material itself is not copyrightable, and facts are not, then it doesn't matter what sites claim about it. postdlf (talk) 20:56, 24 June 2019 (UTC)
 * I haven't passed judgment on whether it is copyrighted yet, but it does need to be looked at. There's a large problem with everyone saying "it's publicly available, so copyright doesn't apply!" above. Databases of facts can be copyrightable, and some of the figures (the diameter) may not actually be "facts." One of the sites say numerical calculations can change quickly.

 * Pinging CCI regulars and  for assistance with the copyright question. –dlthewave ☎ 22:59, 24 June 2019 (UTC)
 * Diameters are publicly available at the Planetary Data System. In the JPL data base, the physical data of an object is always sourced. For the scope of this AfD, all diameter data comes from the NEOWISE mission.  R fassbind  – talk  02:26, 25 June 2019 (UTC)
 * Speedy Delete as per copyright concerns above. Otherwise, this should be deleted anyway because wikipedia is not an WP:INDISCRIMINATE collection of knowledge nor a WP:DIRECTORY.--Rusf10 (talk) 20:23, 24 June 2019 (UTC)
 * Additional Comment Erm, do you some of you people even know how copyright works? minorplanetcenter.net is an NPO of Harvard and Smithsonian, the only copyright material are the images. The collected data is shared data, if the data is fact data. You can not copyright factual information. Hence you can not copyright this information. Govvy (talk) 21:47, 24 June 2019 (UTC)
 * Keep notable per WP:LISTN. Policies WP:NOTPAPER, WP:ATD and WP:PRESERVE ...deletion is not appropriate. Lubbad85  (☎)(Edits) 03:30, 25 June 2019 (UTC)
 * Comment in response to ping. I'm not the best person to ask, US copyright never ceases to perplex me. Here, for what it's worth, is my initial take. There two separate questions here, the list data (number, name, diameter, etc.), and the meanings of the names (in pages that actually have any of those, which as far as I can see does not include those listed here, which appear to be empty):
 * The listed data seems to be devoid of creative content, and is ordered in way that is available to anyone (by number); hosting it here appears to be acceptable based on WP:copyright in lists.
 * The meanings are running text giving information that could equally well be expressed in other ways, and so eligible for copyright protection. As an example, something like "Michelle Abi Hackman (born 1993) was a finalist in the 2010 Intel Science Talent Search, a science competition for high-school seniors, for her behavioral- and social-sciences project. She attends the John Miller Great Neck North High School, Great Neck, New York, U.S." was copy-pasted from here in 2016 (Internet Archive is down, so I haven't been able to verify whether that page existed before that time). The copyright statement of that website reads "", which seems clearly to indicate that the content is not unambiguously in the Public Domain. It may be, of course, that it was copied there from some other source which is verifiably PD, in which case it needs to be provided with attribution; otherwise it should be removed. Justlettersandnumbers (talk) 09:46, 25 June 2019 (UTC)
 * The meanings of minor planets is now attributed with . This has previously been done to some individual pages only. I don't think, however, that this issue belongs to the scope of this AfD.  R fassbind  – talk  18:11, 25 June 2019 (UTC)
 * Public domain resources explains US Government copyright in more detail. Although works created by government employees are automatically public domain, the work of "contractors and grantees" typically is not. JPL would appear to fall under the latter category. Since JPL does claim copyright, it would be prudent to discuss this at the copyvio noticeboard after the AfD is closed. –dlthewave ☎ 03:53, 27 June 2019 (UTC)


 * Keep, according to Minor Planet Center new method will enable minor planet numbering and naming to proceed much more frequently. CabbagePower (talk) 17:30, 25 June 2019 (UTC)
