Talk:Kepler-22b

This chart is copied straight out of the article for Gliese 581 g.
Does anyone else think it would be a good idea to make it a standard chart for all extra-solar planets that are compared to Earth?
With the relevent values swapped in of course.

I do think Earth's comparable figure should be included. I believe it is 14C from the article Earth. Comparison with Earth is I imagine a point of great interest in an article like this 86.184.160.59 (talk) 12:58, 7 December 2011 (UTC)

I would also have to agree with this. Thing that makes this planet have such hype about it and a reason we are all here making edits is the fact that it is comparable to earth. I think it important to have an easy chart like this to allow us to see the details quick and easy. Also it allows a spot of the information to be added quickly as it continues to come out. MathewDill (talk) 16:09, 8 December 2011 (UTC)

Since no one disagree with two agree votes I will add it.24.79.40.48 (talk) 00:27, 15 December 2011 (UTC)

These charts are nonsense and should not be used. Please see discussion at Equilibrium_Temperature. Also, 2 of the references don't point anywhere. Q Science (talk) 10:15, 15 December 2011 (UTC)

In fact, none of the temperatures seems to be supported by either of the sources. Dubious indeed...--Roentgenium111 (talk) 19:38, 26 October 2012 (UTC)

the references have to be corrected as they didn't copy over correctly http://en.wikipedia.org/wiki/Gliese_581_g#Temperatures

In citation #7 it suggest that the gavity for the two different types of planets it could be. That is 1.75 for rocky planet and 6.17 for a neptune like planet. Would it be worth noting that is has an estimated gravity range between 1.75-6.17 or is this to early to even suggest?MathewDill (talk) 16:14, 8 December 2011 (UTC)

It's not too early to suggest a range of masses and thus gravities. Something that size and dark must be planetary in composition. It must be in the earth-neptune range of densities.

I think citation #7 is wrong. If the object has the same density as earth, its surface gravity would be 2.4G. If it is neptune-like with a density of 1.7 then its 'surface' gravity would be 0.75G. (i.e. as compared to earth, 2.4^3 volume. 2.4 farther away. 1/2.4^2 for 1/r^2 so for same density 2.4G. For (1.7/5.5) times the density, 2.4*1.7/5.5=0.75G)

Please be skeptical about citation #7.

See my reply below. (It's now ref. #8.) (And please sign your post(s)!) --Roentgenium111 (talk) 00:37, 11 December 2011 (UTC)

Yeah is the gravitational force the same on Kepler 22b I do not know what it is. 2600:1016:B029:977:20C5:6ECC:ADAF:9FA (talk) 21:24, 8 March 2025 (UTC)

This should be on the newsfeed at the front wiki page --NarlySai — Preceding unsigned comment added by 82.42.184.75 (talk) 16:59, 8 December 2011 (UTC)

Okay everyone. Firstly, there is not enough information currently available about the planet. Secondly, too much information is being added which is either irrelevant or repetitive then being removed by one Wikipedian, whilst being reverted by another. This has got to stop. This shouldn't be the most massive article or even an average sized one. The amount of actual data available should be reflected in the article's size and if this means just one paragraph and an infobox, so be it. I just wanted to stress this. — Preceding unsigned comment added by KirtZJ (talk • contribs)

Personally I wouldn't sweat it. This happens any time an important scientific discovery is announced. Eventually the dust will settle and the article can be tidied up. Regards, RJH (talk) 17:07, 9 December 2011 (UTC)

Exoplanet has updated it to .21 jupiter radi from .234? Some good news. http://www.exoplanet.eu/catalog-all.php?&munit=&runit=&punit=&mode=-7&more=

--Matthurricane (talk) 03:24, 10 December 2011 (UTC)

This line from the page is misreported in the media and makes no sense whatsoever.

"It has been estimated that it is probably a "Neptunian" gas planet with a mass of ~35 Earth masses, but in the "best case" it could be an ocean world with only some 10 Earth masses."

A Neptunian planet would have a low density, so for a fixed radius it would have a low mass. A more earth like ocean planet would have a higher density, so for a fixed radius it would have a higher mass. The referenced article either transposed the numbers or the writer doesn't understand basic math. If you watch Bill Boruki's presentation at the Kepler Science Conference he shows a slide presenting the different composition possibilities for Kepler-22b. You can see from the slide that a higher mass planet would be a denser more ocean like planet. I tried to correct this error in the article, but someone reverted it. This should be fixed, since it is an obvious error in the referenced article. Martin Cash (talk) 16:50, 10 December 2011 (UTC)

Thanks for noting. It seems the reference uses "Neptunian" strictly in the sense of "mass similar to Neptune's", so a "Neptunian" needs not be a gas giant. So they apparently made no factual errors, but only used unfortunate wordings. I've tried to fix it in the article.

Do you have a link to Boruki's slide? That would be a good source... --Roentgenium111 (talk) 00:16, 11 December 2011 (UTC)

PS: Do you mean this slide ? According to it, a water planet of this size would only have some 4 Earth masses, even lower than the referenced article's value. And the 35 Earth-masses might correspond to an Earth-like composition, according to the slide. But such a massive "terrestrial" planet sounds very dubious to me... --Roentgenium111 (talk) 00:33, 11 December 2011 (UTC)

Yes, that's the slide. The text in the article should be updated to reflect that slide, not the misreported line from the media. Thanks.Martin Cash (talk) 02:28, 11 December 2011 (UTC)

Well, the slide doesn't say which of the compositions is most likely, which is a useful info from the PHL website IMO. Personally, I would expect Kepler-22b to be a "gas dwarf" like Kepler-11f with only some 2 Earth masses, since it's even cooler than 11f (thus being able to hold even more hydrogen). But I haven't seen any source stating that opinion. --Roentgenium111 (talk) 19:09, 11 December 2011 (UTC)

The article says that additional confirmation data was provided by ground based telescopes, but doesn't clarify exactly which method/s were used. Would it be correct in assuming that it is also the transit method based on subsequent transits or was it observed also using another different method ? --EvenGreenerFish (talk) 20:48, 10 December 2011 (UTC)

The paper mentions data acquired at the WIYN 3.5m, although the radial velocity data was only an upper limit. The paper is now linked to in the external link sections so you can see for yourself. The secondary sources mentioned nothing beyond "Sptizer and ground based observatories." Sailsbystars (talk) 21:35, 10 December 2011 (UTC)

Is the Article Title Name best phrased as: "Kepler-22b" (hyphen/no-space) - Or - "Kepler-22 b" (hyphen/space) - Or - "Kepler 22 b" (space/space) - Or - "Kepler 22-b" (space/hyphen) - Or - "Kepler 22b" (space/no-space) - Or - Some Other? - Seems there may be ample examples for the various phrasings - For Example, see "Kepler-10b" and "Kepler-16b" and "Kepler-22b" (per SIMBAD) - AS WELL AS - "Kepler-22 b" (per UPR Arecibo) and "Kepler-22 b" (per EPE) and "Kepler-22 b" (per EDE) and "Kepler-10 b" (per NASA) - AS WELL AS - "Gliese 581 d" and "Gliese 581 g" - AS WELL AS - "Kepler 22-b" (per Sci Am) - AS WELL AS - "Kepler 22b" (per CAS) - ALSO SEE - the Official Wikipedia "Extrasolar Planet" Naming Convention - AND - Nomenclature of "Extrasolar Planets" - AND - Astronomical Naming of "Extrasolar Planets" - AND - an earlier related Naming Discussion (thanks to Aldaron) - AND - the Official IAU "Extrasolar Planet" Naming Convention - in any case - Enjoy! :) Drbogdan (talk) 23:42, 10 December 2011 (UTC)

I believe "Kepler-22b" without spaces seems more appropriate. – Phoenix B 1of3 (talk) 03:13, 11 December 2011 (UTC)

"Kepler-22b" is the formatting on the Kepler discoveries website, I think it makes sense to keep this. Hekerui (talk) 13:27, 11 December 2011 (UTC)

I'd go with SIMBAD and the exoplanet database, which are pretty close to the final word in these matters. Except apparently they disagree. The Kepler-22 part seems to be pretty standard, but as to whether the b gets a space or not there does not seem to be a single answer. Argh! For now I think we should just leave the title be and go with the mantra of WP:AINT. Sailsbystars (talk) 13:32, 11 December 2011 (UTC)

The general question of whether there should be a space between the star number and the planet letter has been the subject of much past discussion, both are used in the literature, where the decision is generally a matter of a given publisher's editorial policy, and not one of established guidelines. Most comprehensive online databases include a space and this corresponds to the only statement on the matter that I'm aware of. — Aldaron • T/C 18:38, 11 December 2011 (UTC)

There may be a major database that uses it that way, but we should make Wikipedia articles on Kepler objects uniform in style, which means not using a space. Please check the other similar articles you started - I suspect you made a mistake. Hekerui (talk) 21:52, 11 December 2011 (UTC)

I believe you misunderstand the point, which is to be have a style that reflects actual use. As explained, both the IAU and all databases use a space. This has been explained before. — Aldaron • T/C 02:27, 12 December 2011 (UTC)

In that case a centralized discussion about changing all the article names to reflect your concerns should decide that. However, I don't see consensus on the discussion page you linked. Regards Hekerui (talk) 15:00, 12 December 2011 (UTC)

As Wikipedia:Naming conventions (astronomical objects)#Extrasolar planets states that either form is acceptable and neither name has particular prominence on Google scholar, I'd like to suggest just leaving it be. Regards, RJH (talk) 16:43, 12 December 2011 (UTC)

It could be made searchable by all of those. I forget how to do it, but there is a way. 64.134.29.243 (talk) 19:40, 12 December 2011 (UTC)

I notice that certain notable exo-bodies get proper names (like Wolf, or Lalande, Crab Nebulae etc...) will Kepler 22b receive one? As it seems that it certainly does qualify. 64.134.29.243 (talk) 19:43, 12 December 2011 (UTC)

There are no "official" rules for when stars or exoplanets qualify to get a proper name (unlike the situation e.g. for minor planets). Since no single exoplanet has received a proper name yet, I doubt this one will get one. --Roentgenium111 (talk) 20:04, 12 December 2011 (UTC)

If it does, I vote for "Krypton", just for the fun of it. It fits the general description. :D

--72.196.104.217 (talk) 17:05, 16 December 2011 (UTC)

I'd like to know more accurate list of transit dates for this object. The current dates mentioned in the article are far too vague (ie 1st - "mid-2009". 3rd - "late 2010"). If the orbital period is 290 days (article also contradicts by claiming 289 on same page), then one should be able to accurately extrapolate a complete list of transit dates. --EvenGreenerFish (talk) 05:05, 27 August 2012 (UTC)

The exact dates you added in 2012 ("Dec. 2010, May 2011") blatantly contradict the period claim... Did you just (mis)calculate them yourself, or did you have a (non-mentioned) source? --Roentgenium111 (talk) 16:21, 13 May 2013 (UTC)

This article has the actual three transits used in the confirmation process listed in Barycentric Julian dates.

BJD2454966.69775 +/-0.002182 (three dates cited: 13, 14 & 15 of May)

BJD2455256.55988 +/-0.001853

BJD2455546.42440 +/-0.00191 (one date cited: 1 October)

I have attempted to reconcile these dates in UTC without much success. Though within the article, at least two of the transit dates are explicitly mentioned, though I'm not sure as to which format.--EvenGreenerFish (talk) 14:47, 20 May 2013 (UTC)

Thanks for working on it, but which article has those transit dates? The BJD dates and the 1Oct. 2011 are in the discovery article, but the "cited" May dates aren't. This WP article needs a reliable source for them if they should stay. BTW, the 3rd transit wasn't in Oct. 2011, but in the "2010 holiday season", according to the source we have (as well as maths).--Roentgenium111 (talk) 15:45, 20 May 2013 (UTC)

PS: The three BJD dates are 15 May 2009, 1 March 2010, 15 Dec. 2010 (Univ. Time each) according to ...--Roentgenium111 (talk) 20:11, 20 May 2013 (UTC)

Added to article, removed unref.ed dates. If I calculated correctly, the sixth transit would have occurred on 3 May 2013, when Kepler was unfortunately in safe mode. --Roentgenium111 (talk) 13:42, 22 May 2013 (UTC)

I believe that this is misleading. It depicts a blue/green planet with clouds much like Earth, although little is actually known of whether there is even an atmosphere and may mislead people into making superficial assumptions about habitability. I propose that it should be replaced by a nondescript ball with a comparison in size to the Earth (and possibly Neptune) similarly to many similar articles and the artists conception should be moved to the "Possible Composition and Structure" section. --EvenGreenerFish (talk) 05:28, 27 August 2012 (UTC)

I've done so. Feel free to make it look nicer. --107.203.16.194 (talk) 07:18, 27 December 2012 (UTC)

Actually I think the blue/green is supposed to reference Uranus and Neptune, as given its size 22b is thought to be a mini-Neptune/waterworld and hence why there are no distinguishable landforms in the image. Unlike those two however Kepler-22b is assumed to have the right environmental conditions for particularly bright cloud layers, such as Earth's, to form. So the image is not that bad and about as accurate as can be expected, though perhaps the reality could be misleading to the uninitiated. ChiZeroOne (talk) 13:05, 27 December 2012 (UTC)

In the infobox, the mass is marked as .97 Solar Mass, whereas the actual text gives an estimate by the Habitable Exoplanets Catalog which provides a figure of 6.36 earth masses. Someone should check/update the infobox or the text, whichever is is need of more update. 68.190.33.136 (talk) 15:03, 21 April 2013 (UTC)

The mass of the parent star is listed as .97 Solar Masses, not the planet. ChiZeroOne (talk) 15:12, 21 April 2013 (UTC)

It is listed here as a "Start Class" article, but that is hardly the case anymore. Cliffswallow-vaulting (talk) 03:13, 30 July 2014 (UTC)

It has become a really good article as well. Compliments to whoever did the work. Cliffswallow-vaulting (talk) 03:15, 30 July 2014 (UTC)

The section Orbit states "It has an eccentricity of 0, meaning its orbit is basically circular.[2]", which is not supported by the source and is contradicted in later information on the page.2003:6F:8F18:C300:288D:9EA3:B14:94AD (talk) 12:22, 6 September 2016 (UTC)

The image in the infobox should not be used as it does not follow the usage guide for the template:

This template is part of a group of templates that are used to display information about a specific extrasolar planet.
Images of published planetary properties are preferred where available, especially when they are available from cited publications.
Artist's conception, regardless of the source, should be avoided.
Examples of acceptable images include
* direct images, such as one used for GJ 758 b, in the rare cases where these are available;
* output of a model that is integral to a cited paper, such as the image used in HD 80606 b;
* user-generated images that clearly illustrate published properties, such as the size comparisons currently used in GJ 1214 b or Gliese 436 b.

My edits followed these guidelines but were revered by User:MarioProtIV. I'm opening discussion as to why ...

The habitable zone diagram belongs in the orbit section, not in the infobox.

In the first paragraph, it is stated that Kepler-22b is 600 light years or 180 parsecs away from the earth, but under physical characteristics, it's stated that the planet is 620ly and 190pc away. Both of these statements are cited in the article, but from different sources. I recommend amending the first paragraph to read 620ly, as that statement has more corroborated sources supporting it and also question whether the Brian Dunbar source is entirely accurate. A minor thing, but one that makes us look contradictory and sloppy. 103.251.15.64 (talk) 03:16, 9 November 2022 (UTC)

I've changed the second one to 600ly as all 4 sources connected to the 2 paragraphs surrounding the distance all say 600ly, which remains the publish data by nasa. Lilsharkman (talk) 06:08, 13 March 2023 (UTC)

The parallax from Gaia DR3 (generally the best source for stellar distances) puts the Kepler-22 system at a distance of about 644 light-years. SevenSpheres (talk) 21:36, 18 April 2023 (UTC)
