Kal-Apton

Kal-Apton (also known as Kal-Ai-Ton/Kal-ap-ton, Vulcan/Vulcanis A V, Nevasa V, Ko'vel V, Keid V, Omicron-2 Eridani/Omicron-2 Eridani A V or 40 Eridani/40 Eridani A V) was a planet, the fifth planet in the 40 Eridani star system, in orbit of the star 40 Eridani A. Kal-Apton was a class J gas giant, located around 6 AUs from the central star. 


 * 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 total number seven planets, making it the only other source to infer the existence of this world.
