Sigma Librae

Sigma Librae (also known as Zubenhakrabi, 20 Librae or Gamma Scorpii) was a star system, located in the space of the galaxy's Beta Quadrant. Sigma Librae is a spectral class K orange giant without notable permanent inhabitantion. This star is visible from Sol, 288 light-years distant, in the constellation of Libra. (ST reference: Star Charts)

The Zubenhakrabi system's orbit was the location of a planetary system. (ST video game: Starfleet Command III)

No history or specifics are established for this location in Starfleet Command III, as its name was randomly selected for a system on the game map by the game software. Star Charts annotated the system's lack of inhabitation and allegiance, but established a location consistent with the star's real location. While Star Charts showed this as a K-type star, modern day science catalogs this as a M-type red giant.
