The Ceti Alpha star system was a planetary system located in Sector 25712, Alpha Quadrant.

This system was located a considerable distance from the Delphic Expanse and the planet Denobula as well as three days away from Regula I at an unspecified warp speed. The nearest starbase was Starbase 12. (ENT: "Twilight"; TOS: "Space Seed"; Star Trek II: The Wrath of Khan)

A notable lifeform in this system was the Ceti eel from Ceti Alpha V. (Star Trek II: The Wrath of Khan)

Components[]

Stellar system[]

This was a single star system. The primary Ceti Alpha was a K-type star. (Star Trek II: The Wrath of Khan)

Planetary system[]

In this system, there were at least six planets until 2267, when Ceti Alpha VI mysteriously exploded. This explosion shifted the orbit of Ceti Alpha V, causing massive ecological devastation on this barely M-class world. (TOS: "Space Seed"; Star Trek II: The Wrath of Khan)

History[]

Ceti Alpha V was a "habitable, although a bit savage, somewhat inhospitable" planet chosen by Captain Kirk to resettle Khan Noonien Singh and the crew of the SS Botany Bay after their attempted takeover of the USS Enterprise in 2267. (TOS: "Space Seed")

Six months later, Ceti Alpha VI exploded, shifting Ceti Alpha V's orbit and rendering the latter planet incapable of supporting complex life. This was discovered when the USS Reliant visited the system in 2285. (Star Trek II: The Wrath of Khan)

In an alternate timeline, Ceti Alpha V was the refuge for the last 6,000 members of the Human species in the 2150s and 2160s, survivors of the devastating Xindi attacks on Earth and its colonies, as it was far from the Delphic Expanse. The Enterprise guided a convoy of refugees there. (ENT: "Twilight")

This system's quadrant of origin was inferred based on the position of Starbase 12 as seen in the star chart appearing in the Star Trek: Discovery episode "Magic to Make the Sanest Man Go Mad".
