Class L,O,and P planets are habitable, so are (with terraforming or domes) D,H,K,N,and R. It's all blue so possibly calss O. but there's no canon evidence --Sciofficer 00:59, 17 April 2006 (UTC)
- Non-canon speculation can be discussed in a background section, but it has to have at least some bearing on the events or implications of the episode. I suggest the background on planet classification be pulled unless its importance can be more clearly stated. Aholland 01:48, 17 April 2006 (UTC)
