You know, I have never been able to find a reference to this star in any of my sources, I only know the spectral type because they mention it in dialog. But you know I'd love to know where you are getting your base information on this system. --TOSrules 07:26, Nov 13, 2004 (CET)

The old Star Trek series suffered from the limits they put on star names used -- usually familiar to amateur astronomers. Either they were inconceivably close for the story premise, or inconceivably far away, or not likely to support the story in some way (too large or bright or unstable a star).
In the case of Sigma Draconis, being only 18 light years away, it is inconceivable that the system had not been extensively explored before the incidents of "Spock's Brain". It appears to have been charted by little more than an automated probe and perhaps a pass by a manned vessel (a merchant ship, perhaps). Surely it would have been visited by Archer's Enterprise or the sister ship Columbia, and after the Xindi destroyed Earth ("Twilight"), humans could have scattered in various place, including settling in the equatorial regions of Sigma Draconis VI. Since there was no prime directive at the time, humans could have also hidden by establishing settlements on SD III and IV, isolated from the rest of the populations.
Rigel was very over-used, and perhaps the producers should have done careful checks on stars before they were used in a script, and then kept a record for back-checks. Rigel has several uses implying several planets that are used, including a "cabaret" on Rigel II, a dilithium mine on Rigil XII, the fortress and Kalor on Rigil VII. In addition, it was the next target of the doomsday machine, which was still close to the edge of the galaxy (either the outer rim or one flank). Gcapp1959 07:54, 29 August 2008 (UTC)
