Groombridge 34 was a star system in the Alpha Quadrant.
This was a binary star system. Both the primary Groombridge 34 A and its companion Groombridge 34 B were red dwarf stars. (ENT: "Cold Front"; TNG: "The Naked Now")
History[]
Sometime before September 2151, a major historical battle took place in this system, and the orange color used for the label "Groombridge 34" on an United Earth star chart was an indicator for this event. (ENT: "Cold Front")
Stellar cartography[]
Groombridge 34 was visible from Earth in the constellation Andromeda. This system was approximately 12 light years from Sol.
Location of Groombridge 34 in a United Earth star chart, 2154
In the 2150s, this system's position was labeled on an United Earth star chart which was displayed in several crew and guest quarters aboard the Enterprise. (Star Trek: Enterprise, set decoration))
In 2364, the location of Groombridge 34 was labeled in a star chart of a stellar neighborhood with Sol at the center. This chart was stored in the USS Enterprise-D library computer. Later that year, the chart was scanned by Outpost 63. (TNG: "The Naked Now", production art; TNG: "The Last Outpost")

Background information[]
This star system was only mentioned in writing.
This star's quadrant of origin was inferred based on the position of neighboring locations – 61 Cygni, Alpha Centauri, Procyon, Sol, Tau Ceti, and Wolf 359 – as seen in the star charts appearing in the Star Trek: Discovery episode "Magic to Make the Sanest Man Go Mad" and in the Star Trek: Picard episode "Maps and Legends".
The star chart naming stars within twenty light years of Sol was drawn by Rick Sternbach for the Star Trek Spaceflight Chronology (p. 77) in the late 1970s. This chart showed Earth commercial and exploration routes after the use of warp drive began. There were no commercial or exploration routes to Groombridge 34.
Information on this system was derived from the episodes and real-world sources. The real-world information added to the article was current as of 2025.
The star chart seen in the series Star Trek: Enterprise made its first appearance in Crewman Daniels quarters in "Cold Front". It was also seen in several other episodes of the series, from 2151 to 2154. (For more information, see Federation star charts#United Earth Alpha/Beta star chart)
The identification of orange with a historic battle was made in the key to the star charts in the Star Trek: Star Charts'
There were confirmed two exoplanets in this system. They were a super-Earth planet and a sub-Jovian planet, which were discovered in 2014 and 2017, respectively.
