Trill system

The Trill system was an inhabited planetary system in the Alpha Quadrant. A planet in this system, Trill, was the homeworld for the Trills and the Trill symbionts.

In 2259, the location of this system was labeled on a stellar cartography chart that was seen on the USS Enterprise's ready room viewscreen. This system's symbol had a blue color, indicating that it was affiliated with the United Federation of Planets. (SNW: "Strange New Worlds", "Spock Amok")

The system's location was labeled in a Federation star chart that was in Fleet Admiral Kirsten Clancy's office at Starfleet Headquarters in 2399 and on the bridge of the USS Titan-A in 2401. The Trill system was in or near to Federation space. (PIC: "Maps and Legends", "The Next Generation", "Disengage")

In 2401, this system's position was labeled on a star chart used by Captain William T. Riker during his attempt at finding the last known location of the SS Eleos XII. (PIC: "The Next Generation")

This star system was only mentioned in writing.
The name of this system came from the source material used, the Star Trek: Star Charts and Stellar Cartography: The Starfleet Reference Library, to create the star charts seen in both Star Trek: Discovery and Star Trek: Picard. According to Star Trek: Star Charts (pp. 36 & 46) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), the Trill system was a binary system with a G-class star and a K-class star. The system was a stop on an Earth trade route in the 22nd century and on a major space lane in the late 24th century.
