Vulcanis VII

Vulcanis VII (also known as Vulcan/Vulcanis A VII, Nevasa VII, Ko'vel VII, Omicron-2 Eridani/Omicron-2 Eridani A VII, 40 Eridani/40 Eridani A VII or Keid VII) was a planet, the seventh planet in the 40 Eridani star system, in orbit of the star 40 Eridani A. (ST reference: Spaceflight Chronology; TOS novel: Spock's World)

While the Spaceflight Chronology showed a silhouette of this world, it misattributed the Vulcan system's location as being in the Epsilon Eridani system. Spock's World correctly identified the 40 Eridani location, and mentioned the seven planets, making it the only other source to mention this world.

Vulcanis VII was a larger world, classified as uninhabitable, located somewhat far from the central star at over 50 AUs' distance. (ST reference: Spaceflight Chronology)
