Scope based on gravity

I am concerned about basing the scope solely on gravity. My recollection is that some asteroids are thought to be solid, that is, bound together as a result of their formation process, and not just held together by gravity. Jc3s5h (talk) 14:28, 3 November 2011 (UTC)

Would we still retain similar scope if it just said, "...collection of matter bound together."? AstroCog (talk) 14:33, 3 November 2011 (UTC)
Artificial space objects are also bound together, but that's OK, they are specifically excluded. I notice the guideline is prepared for the future, by specifying "artificial" rather than "man-made". So we are excluding extra-terrestrial spacecraft. Jc3s5h (talk) 14:49, 3 November 2011 (UTC)
Some other topics are not held together by gravity but should be in scope, eg articles on generic concepts, articles on constellations, list articles, voids such as Northern Local Supervoid. Graeme Bartlett (talk) 20:36, 3 November 2011 (UTC)
All excellent and valid points. I think the guideline should be tweaked to accommodate some of this. At the moment I'm not convinced that constellations, or asterisms, are within the scope of an "object", but they are already included via WP:GNG anyway. I'll see what some other WP:ASTRONOMY editors say. AstroCog (talk) 02:06, 4 November 2011 (UTC)
If they are alignment structures (like optical double stars which are not binaries) then they are not even matter that is bound together... 65.94.77.11 (talk) 08:21, 5 November 2011 (UTC)
Wording has been slightly tweaked to accommodate this. AstroCog (talk) 22:04, 5 November 2011 (UTC)
I like it. Regards, RJH (talk) 17:03, 6 November 2011 (UTC)

Notability through naming

Point 3 of the criteria currently reads:

"The object has been the subject of multiple, non-trivial published works. This includes published works in all forms, such as newspaper articles, books, television documentaries and articles in peer-reviewed scientific journals. (...)"
It occurs to me that if an asteroid is named after a particularly well-known individual - for example, 51826 Kalpanachawla - the resulting flurry of news stories about the naming can easily produce "multiple, non-trivial published works" without actually containing any information or analysis. We've emphasised above that naming doesn't itself constitute notability, so I doubt this is intended by the spirit of the guideline - might it be worth adding some language to address this point? Shimgray | talk | 19:49, 8 November 2011 (UTC)
I think this is covered by the "Significant coverage" clause of WP:GNG. But perhaps it needs to be clarified?
"The object has been the subject of significant coverage in multiple, non-trivial published works. This includes published works in all forms, such as newspaper articles, books, television documentaries and articles in peer-reviewed scientific journals. (...)"
Regards, RJH (talk) 21:27, 8 November 2011 (UTC)
Naming itself is a bad guideline. Mostly because naming is usually based on the discoverer's suggestion. If I discovered a random spec of unremarkable dust, and I thought Franz Ferdinand was a cool guy, it could very well end up being named something like 12353 FranzFerdinand. But it's not because I think Franz Ferdinand is a cool guy that my spec of dust becomes notable.
Notable specs of dusts are those extensively studied. If 123535 really is notable, then it shouldn't be hard finding sources to support that, rather than going "Well Franz Ferdinand is a notable guy, therefore this minor asteroid is too". Headbomb {talk / contribs / physics / books} 18:22, 9 November 2011 (UTC)
Just to clarify my original comment, I agree with you entirely :-). I'm just concerned to address the odd cases where the "act of naming" gets notable levels of coverage despite little or nothing being known about the body bar its name, which is definitely outside the spirit of the guideline. Shimgray | talk | 00:18, 12 November 2011 (UTC)
That is why I suggested above that any article about a named astronomical object which is determined to fail notability guidelines be merged into the article about the person it is named after. In the case of 123535, were that article found fail the guidelines, the information should then be merged into the article about Kalpana Chawla. That way no information is lost. -- llywrch (talk) 22:54, 10 November 2011 (UTC)

Visible to the naked eye

Should we use the Class 1 rating on the Bortle Dark-Sky Scale to determine whether an object is visible to the naked eye? I know my own eyes don't even come close to that limit. Regards, RJH (talk) 20:50, 1 December 2011 (UTC)

I had assumed it would just use the "notional" definition of an apparent magnitude >= 6, regardless of whether anyone's looking and what condition they're doing so in! Shimgray | talk | 20:57, 1 December 2011 (UTC)
I use >= 6 apparent mag. Seems the easiest and most widespread way to think about it. Cheers, AstroCog (talk) 21:09, 1 December 2011 (UTC)
For giggles that gives you 5469 stars brighter than vmag 6. -- Kheider (talk) 21:15, 1 December 2011 (UTC)
That's practically nothing at all, astronomically speaking ;-) AstroCog (talk) 03:07, 2 December 2011 (UTC)
I think there may be some stars with Flamsteed designations that are below magnitude 6.0; 63 Ophiuchi for example. If I may, I'd like to suggest using magnitude 6.5 as the limit so that we include all of the 6th magnitude stars (5.5–6.5). Thank you. Regards, RJH (talk) 15:34, 2 December 2011 (UTC)
That sounds fair enough, we could even stretch it to say observed brighter than 6.9 at some point in time, but are there any visible stars that would not meet the other requirements above? Graeme Bartlett (talk) 21:07, 2 December 2011 (UTC)
Anything brighter than seventh magnitude would seem almost guaranteed to fall under the "discovered without the help of modern technology / pre-1850" clause, I'd have thought. Shimgray | talk | 21:19, 2 December 2011 (UTC)
Yes that's true. Regards, RJH (talk) 22:33, 2 December 2011 (UTC)

Examples?

I don't know very much about astronomy. And I realize that people who don't know anything about astronomy probably aren't the targets of this essay/guideline, because they're not the sorts of people who would create random stub articles about non-notable planets or stars.

Nonetheless, I found this essay/guideline a bit abstract. I think it could be helped with a few examples, like maybe a named planet or something that isn't notable (or an un-named one that is), or commonly created non-notable astronomy articles. Just a thought. AgnosticAphid talk 18:32, 3 November 2011 (UTC)

AgnosticAphid, that's an excellent suggestion, and one that we knew would have to be added to the guideline eventually. I'll add some examples to the guideline tonight, if one of the other co-authors doesn't do it first. AstroCog (talk) 18:44, 3 November 2011 (UTC)
Two minor planets for comparison - 532 Herculina and 10979 Fristephenson. Fristephenson easily fails all four - it's dark, it's obscure, it was discovered through a mass photographic search, and there's been no significant research published on it. Herculina probably fails point 4 (Wolf was a pioneer in using photography) but it certainly passes point 3 - two papers explicitly studying it, and significant coverage in a number of others. Shimgray | talk | 21:05, 3 November 2011 (UTC)
I've begun an examples section in the guideline, which includes the 532 Herculina example and non-notable asteroid for which there is no article. AgnosticAphid, is this the kind of thing you had in mind? AstroCog (talk) 02:46, 4 November 2011 (UTC)
Yes, I thought that was helpful. I'd suggest adding "rather than in its own article" to the very end of the section or maybe italicizing "for the individual or character" to make it slightly more clear, even though I know that it's a restatement of the criteria. But overall I think this guideline is great and that the examples help. AgnosticAphid talk 18:56, 4 November 2011 (UTC)
Help out future participants in AFDs: It can be helpful to provide examples various types of objects or things in space which fall just inside or just outside the guideline, and why. Vague definitions just invite endless bickering at future AFDs. Edison (talk) 00:47, 22 November 2011 (UTC)
  • The criteria are left intentionally open-ended so that we're not too restrictive, but I see your point. Do you mean something like, "For example, a main sequence star identified in the Hipparcos catalog but is not the subject of any other studies or articles does not qualify for a stand-alone article."? AstroCog (talk) 04:40, 22 November 2011 (UTC)

Proposal to promote Notability (astronomical objects) to guideline

Suggested change

One suggested change: "The object was discovered before 1850; prior to the advent of stellar astrophotography or automated technology.", change to at least 1950. Fotaun (talk) 17:22, 3 December 2011 (UTC)

Might I ask why you would prefer 1950? That was well after astrophotography came into widespread use. Regards, RJH (talk) 17:28, 3 December 2011 (UTC)
  • Well, it would protect early astrophotography and many already covered objects. Fotaun (talk) 18:32, 3 December 2011 (UTC)
1850 was the date arrived at by consensus. These discussions have been going on for more than two months at WP:ASTRONOMY and WP:ASTRO, so if you are so concerned, you should have jumped in then. Like RJH said, astrophotography was already established by 1950, and even the blink comparator had been in use by astronomers for decades by 1950. The point of this criteria was to allow for objects that are conspicuous enough to have been easily noted by pre-modern astronomers, without the help of much technology. AstroCog (talk) 18:13, 3 December 2011 (UTC)

When may we have a ruling?

Great job with this, and congratulations on all your hard work and this impressive document. Right about now would be a fantastic moment for you all to get this guideline finished and adopted. Can consensus be reached? How many holdouts are there, and their can their concerns be satisfied or it hopeless? What is the next step in the process? Can you give us some idea as to when we might have a decision? Can the holdouts agree to allow adoption with the provisio that further changes may still be made in the future? It's important. Chrisrus (talk) 03:01, 21 November 2011 (UTC)

Proposals can be often be discussed for a month or more and then be closed by an administrator. Just be patient and let it run its course here. There's no rush to have this finish right now as opposed to next month. It's a discussion, not a numbers game, so just be patient. Cheers, AstroCog (talk) 03:06, 21 November 2011 (UTC)

Congratulations...

...on the new guidelines! What's the next step in implementation? Some of us outside this community are concerned that notablity issues be dealt with in a timely manner. Chrisrus (talk) 20:22, 3 December 2011 (UTC)

Deletions

I am upset that this passed, and I am afraid that many articles fellow editors have worked will now be deleted, either now or in the future. Fotaun (talk) 17:22, 3 December 2011 (UTC)

I don't think the spirit of this guideline to delete any pre-existing article that is developed beyond a sub-stub. Articles that people have worked hard on, should be able to achieve near start-class status/upper stub-status without too much editing. -- Kheider (talk) 17:39, 3 December 2011 (UTC)
Kheider is right. I'm not sure why you are afraid. At worst, this guideline could provide a kick in the pants to expand any trivial stubs that have been created. If they can't be expanded, then you should agree that they should be redirected or deleted. For now, I have no intention on hunting for stubs to destroy. I have appealed to the astronomy editor community at WP:ASTRONOMY and WP:ASTRO to keep an eye on new PRODs and AFDs to make sure the guideline is applied correctly and not maliciously. Cheers, AstroCog (talk) 18:07, 3 December 2011 (UTC)
Maybe you two can be trusted to be fair, but Wikipedia can be used by nearly anyone and in the long term, others may not be so prudent. Fotaun (talk) 18:36, 3 December 2011 (UTC)
May I ask a more fundamental question? Do you want to keep these articles because you and others worked on them, or because visitors are likely to look them up during a search? If the former, then you can always choose to preserve them on a web site. If the latter, and you think the pages are unlikely to survive an AfD, then it would be a more general concern and we should take a look at what can be done. Regards, RJH (talk)
What you really want to do is mention somewhere in the article why an object is notable. I also recommend using 3 references and having 4-5 sentences about the object. I had doubts about the new article 2011 UL21 being very notable based on briefly having a Torino scale 1 rating, until I realized, "it is likely the largest PHA discovered in the last few years". That makes it more notable than a newly discovered 10km asteroid confined to the main-belt that has no real notable characteristic. -- Kheider (talk) 18:52, 3 December 2011 (UTC)
Even more than notability, we want encyclopedic content. Fotaun (talk) 19:22, 3 December 2011 (UTC)
The general question of what is encyclopedic content is at a higher level than what is covered by this specialized guideline. Regards, RJH (talk) 21:34, 3 December 2011 (UTC)
Right, this "specialized guideline" violates a higher principle. Fotaun (talk) 22:31, 3 December 2011 (UTC)
Ah well, we can't please everybody. Good luck. RJH (talk) 02:11, 4 December 2011 (UTC)
This sounds suspiciously like "Do not lose the WP:EFFORT", which is actually on the list of bad excuses for keeping a non-notable article. But the real answer is that information should be WP:PRESERVEd, largely by WP:MERGEing it to a notable subject or list. Maintaining a completely separate, stand-alone article is not the only possible way to preserve good work. WhatamIdoing (talk) 03:30, 5 December 2011 (UTC)
Right, we do have both lists of minor planets and lists of stars in constellations that can both serve as destinations for otherwise non-notable astronomical object articles. The one small concern is that the list of minor planets does not include a means to include information about the object's name origin. But I think that can be addressed by adding a column to the tables or by means of footnotes. Regards, RJH (talk) 15:37, 5 December 2011 (UTC)

1992 SY

And let the action begin: Wikipedia:Articles for deletion/(52340) 1992 SY. (jpldata) -- Kheider (talk) 15:33, 8 December 2011 (UTC)

Vested interest?

This guideline contains the following statement:

For the purposes of this guideline, "independent" means independent of the scientist or scientists who discovered the object, or who have a vested interest in studying the object

In this context, do we know what "vested interest" implies? I'd assume that every astronomer has some sort of interest in the objects they study, as well as something at stake in the observations (whether it be professional prestige through published works, defense of their particular favored hypothesis, proof that their model gives good results, or whatever). Where should one draw the line in determining at what point the author of a scholarly paper is sufficiently independent? If an object has 20 different papers from 20 different teams, surely the odds are that at least some of them will be considered sufficiently independent? Regards, RJH (talk) 20:06, 13 April 2012 (UTC)

I wrote that, and I think at the time I was thinking of a case where an amateur astronomer discovered some rock, named it, and then tried to promote the discovery themselves, which may include creating WP articles themselves - so maybe the language should be more about conflict of interest rather than "vested interest". AstroCog (talk) 22:08, 13 April 2012 (UTC)
Yes, I think that would help to clarify the language, at least for me. Thank you. Regards, RJH (talk) 22:38, 13 April 2012 (UTC)

NEOs

I think that notability should automatically be assumed for anything that makes it on to a near-Earth object, earth-crossing asteroid or similar list in a recognised database. Anything that has even a remote possibility in the far future of smashing into the earth and demolishing civilisation is notable by common sense, if nothing else. SpinningSpark 16:00, 8 May 2012 (UTC)

I respectfully disagree, Wikipedia is not a crystal ball so we shouldn't have an article on an object just because it might someday be notable (ending civilization would be pretty notable, admittedly). For the same reason, we don't have articles about random children because someday they might grow up to become president of the US and unleash a nuclear winter that ends human civilization. Notability is not predicted. Notable Earth-crossing asteroids, such as 99942 Apophis can get an article if they have garnered substantial coverage due to their probability of impact.... Sailsbystars (talk) 16:27, 8 May 2012 (UTC)
Exactly. Listing thousands of pages on objects about which virtually nothing is known provides no benefit to the reader and serves only to attract vandalism and rubbish. Common sense suggests it's better to focus on improving the quality of a smaller number of pages about more significant topics. Regards, RJH (talk) 17:03, 8 May 2012 (UTC)
What about Potentially hazardous objects. The very fact that someone has calculated their potential hazard and listed them makes them something of note. SpinningSpark 17:38, 8 May 2012 (UTC)
That list of objects would still be just a directory, which is banned by WP:NOTADIRECTORY. It isn't the job of Wikipedia to track such things, just like we don't cover all the criminals in the Federal penitentiaries. We should just cover those objects that have had significant coverage.
The concept of notability on Wikipedia is a little different than how you are using it. It's not what's individually important to you or I, but rather what has demonstrated importance to a widespread audience through reliable media publications. Now the risk is real and of widespread interest, but individual NEOs do not thereby inherit that notability, per WP:NOTINHERITED. Regards, RJH (talk) 19:09, 8 May 2012 (UTC)
Yes, yes. You don't need to spell out to me how Wikipedia defines notability. I was putting forward a case along the same lines as WP:PROF assumes notability for an academic elected to a select society, or WP:MUSIC for a musician nominated for a major award. There are not so many PHAs and they are studied individually, rather than as a class of asteroid, for obvious reasons. SpinningSpark 00:00, 9 May 2012 (UTC)
Fine. Asteroids that are subjects of individual study should be able to satisfy this criteria. Regards, RJH (talk) 04:33, 9 May 2012 (UTC)
I would like to point out that objects that are virtual impactors in next 100 years are much more notable than random Potentially hazardous objects that may or may not ever pose a real risk. -- Kheider (talk) 04:41, 9 May 2012 (UTC)

True. Looking at the list, I do see a number of objects that are sufficiently notable. However, I can't see the latest discoveries (from 2012) having much Wikipedia notability yet. There only appear to be two objects that have a rating of greater than zero on the Torino scale. Regards, RJH (talk) 14:55, 9 May 2012 (UTC)

2012 DA14 is good example of a recent discovery being notable as it has quite a bit of press coverage. -- Kheider (talk) 18:47, 9 May 2012 (UTC)
Okay. But is that an exception or the rule? Regards, RJH (talk) 18:55, 9 May 2012 (UTC)
I don't think we need to change any of our guideline, as the press coverage will automatically help the topic over the line if the object has a chance of hitting the earth. Graeme Bartlett (talk) 21:26, 9 May 2012 (UTC)
I agree. Why should these objects be given special treatment. One of the goals of the guideline was to take away special treatment to classes of objects. If one of these objects have sufficient coverage to meet the criteria, then it can get an article. If it doesn't meet the criteria, then I'm not sure what argument could be made in favor of it. Cheers, AstroCog (talk) 02:13, 10 May 2012 (UTC)
