Stellar system[]

This was a single star system with a red dwarf primary.

History[]

In late 2367, at the start of the Klingon Civil War, the House of Duras gathered a large fleet near this system while preparing to launch an offensive against Gowron's forces. (TNG: "Redemption")

Stellar cartography[]

In 2256, the system's location was labeled on the star chart "Alpha/Beta Quadrant Overview" in the ready room aboard the USS Discovery. It was located within the territory of the Klingon Empire. (DIS: "Magic to Make the Sanest Man Go Mad", "The War Without, The War Within")

A year later, the system's location was labeled on the star chart showing the trajectory of Lieutenant Spock's shuttle. (DIS: "An Obol for Charon")

In 2258, the system's location was labeled on a star chart seen on the main viewscreen of the USS Enterprise. (DIS: "Such Sweet Sorrow, Part 2")

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 was a red Klingon Empire logo, indicating its affiliation with the empire. (SNW: "Strange New Worlds", "Spock Amok")

On stardate 1292.4, the location of this system was labeled in a chart used during a Section 31 Alpha Team briefing. (Star Trek: Section 31)

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 Beta Thoridor system was in or near to neutral space. (PIC: "Maps and Legends", "The Next Generation", "Disengage")

Although Beta Thoridor was called a planet in the Star Trek Encyclopedia, 4th ed., vol. 1, p. 81, it was identified as a system in the Star Trek: Star Charts and in the Stellar Cartography: The Starfleet Reference Library. This source material was used to create the star charts seen in both Star Trek: Discovery and Star Trek: Picard.
Information on the system's primary came from Star Trek: Star Charts (p. 61) and Stellar Cartography: The Starfleet Reference Library ("Stellar Cartography", pp. 27, 30; "Federation Historical Highlights, 2161-2385"). The Beta Thoridor system was identified as a Klingon system in a star chart created by Scribe K'Tark in the Year of Kahless 893 (2266) for the Klingon High Council.
In the Bayer designation, which was a system of stellar classification, the Greek letter indicated the brightness of a star in a constellation. In this case, Beta Thoridor would be the 2nd brightest star in its constellation.
