Tau Ceti is a star with an associated star system, approximately 11.8 light years from Sol. The Tau Ceti system was the site of the Tau Ceti Accords, a treaty between Vulcan and the Andorian Empire. (ENT episode: "Shadows of P'Jem")

The system has a vast amount of interplanetary debris, making space travel extremely difficult. Kaferia itself can only be approached via its poles. (ST reference: The Worlds of the Federation)

Tau Ceti was the intended destination of Khan Noonien Singh's Augment followers when they were launched into space aboard the sleeper ship SS Botany Bay in the year 1996. (TOS - Star Trek 2 novelization: Space Seed)

During the Earth-Romulan War, Tau Ceti (also referred to as Kaferia) fell to the Romulans in June of 2156. Following his defeat at the Second Battle of Deneva, Admiral Valdore quickly redeployed his forces and attacked the Earth colony at Tau Ceti IV. The Coalition of Planets forces protecting Tau Ceti were a combined Starfleet-Andorian-Tellarite task force led by Atlantis (NX-05), which was destroyed by the Romulans. The Romulan conquest of Tau Ceti gave the Romulans a forward operating base only 11 light years from Earth. (ENT - The Romulan War novel: Beneath the Raptor's Wing)

Tau Ceti IV was the location of Amber, according to Starfleet's fictional Kobayashi Maru scenario training simulation (TOS movie: The Wrath of Khan). Amber was the home port of the ECS Kobayashi Maru. (ENT - The Romulan War novel: Beneath the Raptor's Wing)

In the mid-2260s, the USS Enterprise engaged and defeated a Romulan vessel near Tau Ceti. Enterprise deployed a Tactical Assault known as the "Cochrane deceleration maneuver." (TOS episode: "Whom Gods Destroy")

In the mirror universe, the Terran Empire lost twelve ships in a battle at Tau Ceti against alien rebels in 2155. This battle represented a major setback for the Empire. (ENT episode: "In a Mirror, Darkly")
