Spectral classes are real science. Every bit of information on this page is scientifically accurate. --BlueMars 23:09, 24 April 2006 (UTC)
Yes, however, this is all real world information, therefore what does it have to do with Star Trek? All that links here are real world star pages. --Alan del Beccio 01:46, 20 October 2006 (UTC)
The term spectral type was used in "Spock's Brain", that is the closest reference I can find to this term. --Alan del Beccio 22:10, 31 January 2007 (UTC)
Yes, and terms like G-type star (the Insectoid ship in "Beyond the Farthest Star" was found far away from a G1 star (hence, the episode's title)), F-type star, O-type star etc sneak up in several episodes, so the stellar classification system is still in use in the 24th century. --Jörg 08:25, 1 February 2007 (UTC)
Additionally, a graphic of the O-type star from "Juggernaut" lists it as
  • Astronomical Body
  • Spectral type = O
More evidence for the spectral classification and maybe reason to move this page to "Spectral type". --Jörg 16:48, 26 March 2007 (UTC)
