Agena (also known as Beta Centauri or Hadar) is a multiple star system, located about 160 parsecs (530 light-years) from Earth, where it is visible as the second brightest system in the constellation of Centaurus in the galaxy's Beta Quadrant. (TOS comic: "The Expansionist Syndrome")

History and specifics[edit | edit source]

Agena was the location of a planetary system in orbit, including fourth planet Hadar IV. (ST video game: Starfleet Command III, TOS comic: "The Expansionist Syndrome")

The Federation starship USS Agena was named for this system when it was authorized for construction. (ST reference: Star Fleet Technical Manual)

Since this is a "real" star system, we know details about its location and makeup not revealed in its Star Trek mentions, where it was only mentioned by name.

By the 2370s decade, Hadar was a holding of the the Klingon Empire, and Hadar IV was considered a friendly port of call by 24th century Klingon Defense Force starships. (ST video game: Starfleet Command III)

In gameplay, the planet name was part of a list that were applied to planets on the game map, with no history or specifics established for the random attributes assigned to them.
