Minara was the primary star of the Minarian star system that supernovaed in 2268. Its counterpart in the antimatter universe was located twelve degrees south of the galactic plane.

At that time, the star system hosted at least two inhabited planets – one was used by the Vians, the other was home to Gem's people. (TOS: "The Empath")

While inhabiting the body of Dr. Janice Lester in 2269, James T. Kirk referred to events immediately preceding Minara's supernova in an attempt to convince Spock of his identity. (TOS: "Turnabout Intruder")

In 2270 the USS Enterprise set course for the dead star in the antimatter universe that corresponded with the Minara supernova, where it emerged back into the familar "positive matter universe." (TAS: "The Counter-Clock Incident")
