Class KEdit

Theta 116 VIII is a "Class K Transjovian" planet (per bridge display). It is unclear if "Transjovian" contradicts the Star Charts listing or simply is a further specification of the "Adaptable" type. The preceding unsigned comment was added by Cid Highwind (talk • contribs).

I assume the current information comes from the Star Trek: Star Charts? I agree that it is fairly consistent with canon, and that there is no need not to follow up on it. In other words, I like it :) -- Harry 05:03, 25 Dec 2003 (PST)

Correct, it's Star Charts plus the Transjovian (sub-)type from (TNG: "The Royale"). -- Cid Highwind 08:26, 25 Dec 2003 (PST)

VfD for Planetary classes from Star Trek: Star Charts Edit

Class A, Class B, Class C, Class E, Class F, Class G, Class H, Class I, Class N, Class Q, Class R, Class S, Class T
  • Appears to be based solely on Star Trek: Star Charts, with no true-to-television-Trek references. --Alan del Beccio 07:47, 17 Aug 2005 (UTC) Updated - 08:05, 20 Aug 2005 (UTC)
  • Delete. Great book, it's when people take it for canon it becomes more then it's worth. - AJHalliwell 08:11, 20 Aug 2005 (UTC) (UPDATE) This planet Scrabble is getting out of hand. Delete all, and any other non-cited that is put on here. - AJHalliwell 08:30, 20 Aug 2005 (UTC)
  • Keep Class H, was mentioned in "The Ensigns of Command" as far as I'm aware. Could be rewritten, though. Redirect all non-canon others to Planetary classification instead of deleting them, to avoid future trouble. -- Cid Highwind 10:59, 20 Aug 2005 (UTC)
  • Agreed to delete or redirect all non-canon planet classes -- I don't even think there is need for a deletion proceeding -- some of these articles have been deleted numerous times! -- Captain Mike K. Barteltalk 21:50, 21 Aug 2005 (UTC)

Merge suggestionEdit

This table is a little messy. It only contains "canon" classes (of course), but then also lists non-canon (=Star Charts) information for these classes. Star Trek: Star Charts has the same table, but leaves cells empty that are already listed here. This helps no one... I suggest to have the complete table (all classes, all info) listed at ST:SC (because most of the info here is from that book), and have a smaller table listing all referenced classes with examples, but without unreferenced info, here. -- Cid Highwind 09:43, 23 March 2006 (UTC)

Merge with... Edit

With virtually no information left in the main text, I suggest to merge this (and all other "Star Charts planetary classes") to the main article about planetary classification, alternatively with the Star Trek: Star Charts article itself. -- Cid Highwind 09:31, 24 November 2006 (UTC)

Star Trek Star ChartsEdit

why are the Star Trek Star Charts an accepeted souce here?--Shisma 15:38, 23 November 2006 (UTC)

They aren't. Feel free to fix it. :) -- Cid Highwind 15:40, 23 November 2006 (UTC)

Theta 116 VIII Edit

If you look at the computer screen in "The Royale", Theta 116 VIII is actually listed as class C not class K as someone here is suggesting. The preceding unsigned comment was added by (talk).

Have you actually looked at the screenshot I provided? You can clearly see on this DVD screenshot, that it is K, not C. Look at the "C" in "class", only 5 letters next to the "K" and you'll see the difference. For everyone else, the image and the previous discussion can be found here. --Jörg 09:04, 24 October 2006 (UTC)

Class VEdit

The first change introduced an HTML-error, because a part of the table structure was deleted. The second one was a link to Class V (Gas Core), which seems non-canon to me... -- Cid Highwind 10:20, 18 Jan 2004 (PST)

Old VersionEdit

Class Name
Class A: Geothermal
Class B: Geomorteus
Class C: Geoinactive
Class E: Geoplastic
Class F: Geometallic
Class G: Geocrystalline
Class I: Gas Supergiant
Class O: Pelagic
Class P: Glaciated
Class Q: Variable
Class R: Rogue
Class S: Ultragiant (small)
Class T: Ultragiant (large)

these are the classes i ended up removing, REASON: No canon mentions. --Captainmike 23:13, 3 Jun 2004 (CEST)

Class N Edit

I was going through "Night Terrors" frame by frame, at the part where Data is looking throug the computer for explosives.. One frame shows:

Non-oxidizing chemical explosive used in Class-N(2) planetary environments for engineering applications.
This substance is unstable in oxygen atmospheres and must be handled in accordance with SFRA 2884.3 safety regulations.

This seems to make Class N canon? Skold 04:18, 28 January 2006 (UTC)

I would say so. --Alan del Beccio 04:46, 28 January 2006 (UTC)
Uh... I just tidied up after the Class N article was deleted for not being referenced. Apparently, this note was not used in the deletion discussion regarding "Class N"? -- Cid Highwind 09:43, 23 March 2006 (UTC)

Class PEdit

Class P should be deleted from the table since it is not canon. A P-class planet has never been mentioned on screen even though many seem to fit into the Star Charts description of one. The preceding unsigned comment was added by (talk).

Did any of the episodes listed actually mention the phrase "class p" -- also, all Star Charts info should be moved to background section -- Captain M.K.B. 15:21, 23 March 2006 (UTC)
Definitely not "Broken Bow" or "What Are Little Girls Made Of?" - not sure about the two DS9 episodes, but I believe those references are assumptions as well, based on the fact that the episodes dealt with "glaciated" planets. -- Cid Highwind 12:29, 24 March 2006 (UTC)

Class T Edit

Janeway mentions a "T Class" gas giant in "Good Shepherd". I've added it to the list. Skold 03:58, 25 March 2006 (UTC)

Hidden textEdit

What is the deal with all the suppressed text in the table (evident in the code)? Is that supposed there? -- Capricorn (talk) 23:59, October 31, 2016 (UTC)

Anyone? Please? I'd like to make what I think are important improvement to that table but am worried about messing some kind of thing up... Capricorn (talk) 06:35, November 9, 2016 (UTC) Final last ditch effort bump -- Capricorn (talk) 05:21, November 27, 2016 (UTC)

I've gone and removed it. Below I've preserved the entire table but with the stuff I removed made visible I realize that's not the clearest way to document what I've done, but sorry, anything more was beyond my understanding of these infernal tables. -- Capricorn (talk) 18:25, December 1, 2016 (UTC)

Class Description Examples Age

Class O Edit

Forgive me if I'm out of protocol. I'm watching Star Trek: Voyager on Netflix and a Class O planet was just mentioned as having an Oxygen / Argon atmosphere (Season 2 Ep. 1 "The 37's). Why is Class O not included in the list? --Savage Valkyrie (talk) 04:24, February 17, 2017 (UTC)

It was Class L. --Alan del Beccio (talk) 04:56, February 17, 2017 (UTC)
