Sigma Draconis system

The Sigma Draconis system

The Sigma Draconis system was an inhabited planetary system.

This system consisted of a primary and nine planets. Primary was named Sigma Draconis. Three planets, Sigma Draconis III, Sigma Draconis IV, and Sigma Draconis VI, were populated by native species. These three planets were classified as M class. The other planets in the system - Sigma Draconis I, Sigma Draconis II, Sigma Draconis V, Sigma Draconis VII, Sigma Draconis VIII, and Sigma Draconis IX - were not M-class. There were surveys and long-range scans of this system. Information on the system was stored in the library computers of Federation starships. In 2268, the USS Enterprise entered the system to search for Commander Spock's brain. (TOS: "Spock's Brain")
