Deneva, also known as Deneva Prime, was the inhabited prime planet in its star system. The planet was affiliated with the United Federation of Planets. By the 2260s, the Human citizens of this planet were called Denevans.
The Deneva colony was established on this planet in the mid-22nd century. This planet was, also, the location of the Deneva Station. The reason for colonization was that the planet would serve as a freighting-line base in the sector. Supplies would be sent to the miners in the system's asteroid belt and what was mined in the asteroids would be sent back to Deneva for transfer to other Earth, and later Federation, worlds and colonies. Deneva was considered one of the most beautiful worlds in the galaxy. In 2267, there were over a million inhabitants on this world, with more than a hundred thousand living in the capital city alone. The nearest starbase was Starbase 10. (TOS: "Operation -- Annihilate!", ENT: "Horizon", "Rogue Planet")
Montgomery Scott worked in this freighting line as an engineering adviser early in his career. He was on a couple of runs.
In late 2266 – eight months before the visit of the USS Enterprise – space vessels from Ingraham B brought an infestation of neural parasites. These parasites would have wiped out the colony, as they had Ingraham B and at least three other civilized worlds, had not Captain Kirk and his crew destroyed them. Many people died from the infestation, including Kirk's brother Sam, just before the arrival of the Enterprise, and his wife Aurelan, soon after. The couple had moved to the planet with their son Peter not long before the infestation. (TOS: "Operation -- Annihilate!")
