Theta 116 solar system

The Theta 116 system was a planetary system, with at least eight planets, that was located somewhere in the Alpha or Beta Quadrant. This system had remained unmapped by the United Federation of Planets until 2365.

That year, the scattered remains of the 21st century Earth spaceship Charybdis were discovered in orbit of Theta VIII in this system by a Klingon cruiser. Subsequently, the USS Enterprise-D entered orbit to investigate. (TNG: "The Royale")

In the episode's script, Theta VIII was the furthest planet from its primary.
