History and specifics
Kappa Beta was scanned as part of the starship USS Enterprise's initial exploration of the Kappa system. The planet's orbit was tilted upward from the system's plane of the ecliptic. A star chart denoted Kappa Beta as one of three larger planets in the system, possibly a gas giant. (TOS comic: "Creeping Death")
- It was unclear why the second planet was designated Kappa Delta and the fourth Kappa Beta, when the Greek language uses beta second and delta fourth.
