Kappa Zeta was a planet, the sixth planet of the Kappa system, located in the galaxy's Alpha or Beta Quadrant.
History and specifics[]
Kappa Zeta was scanned as part of the starship USS Enterprise's initial exploration of the Kappa system. It had a highly eccentric orbit which put its closest point in the system just within the orbit of the third planet, but most of the time it was the outermost planet. A star chart of the system denoted Kappa Zeta as one of three larger planets in the system, possibly a gas giant. (TOS comic: "Creeping Death")
