Talk:Sudarsky's gas giant classification

message: I've noticed that this system is being applied to extrasolar planet articles. If you are going to do this, please make sure you have a reference where the particular Sudarsky class is assigned (note that Extrasolar Visions is a speculative site, and the speculations there should not be presented as fact). As far as I have found, the only place where the classes in this system are applied to specific planets is the paper outlining this system. Even then this should be presented as a theoretical calculation, not as a fact - these planets have not been directly observed, so saying what the dominant cloud type is is impossible.

replies: text: Where exoplanets have been measured for appearance, or should have been measured but can't be seen (hinting at low albedo), or have been measured for atmosphere: I've been putting their stats in the article text to show how well Sudarsky's predictions have held up. As a bonus these measurements give real results for "appearance of extrasolar planets". -- Zimriel (talk) 04:14, 12 March 2008 (UTC)

message: * OBJECT I don't think Sudarsky is prevalent enough to merge into gas giant, besides, it'd clutter the gas giant article alot. Zzzzzzzzzzz 03:03, 24 January 2006 (UTC)

Is it really necessary to leave open the possibility that a planet the size of Jupiter might be hiding in the inner solar system somewhere? Algr 06:23, 28 January 2006 (UTC)

I've done some tweeking to David Sudarsky's system.  So it includes Neptune's class, the Venus & Mars temp. giants, plus the NH4SH giant & the Iron giant. — Hurricane Devon ( Talk ) 00:18, 6 January 2006 (UTC)

replies: text: Ok, no problem. I'm interested in how did you come up with this classification? AFAIK iron giants have been discussed before, but others are unknown to me.--Jyril 10:40, 24 January 2006 (UTC)

text: I would strongly oppose including the Sudarsky system in the extrasolar planet template, because it is speculative. Infoboxes should primarily be used for a short summary of data rather than presentation of speculation. Chaos syndrome 23:59, 29 January 2006 (UTC)
