The Ophiucus system, also known as the 36 Ophiuchi system, was an inhabited planetary system in the Beta Quadrant.
Components[]
Stellar system[]
This was a trinary star system. It was organized into a single star system and a binary star system.
The central star of this system was Guniibuu (the proper name for 36 Ophiuchi A). It was the primary in the binary star system. Both this star and its companion 36 Ophiuchi B were K-type dwarfs.
The tertiary star 36 Ophiuchi C was the primary of a single star system. It was a K-type dwarf, as well. (ENT: "Cold Front")
Planetary system[]
In this system, there were at least six planets, including Ophiucus III and Ophiucus VI. (TOS: "Mudd's Women"; TAS: "Mudd's Passion")
History[]
In 2256, during the first Federation-Klingon War, the USS Discovery routed an attack of this system by Klingon warships. (DIS: "Choose Your Pain")
Stellar cartography[]
The Ophiucus system was visible from Earth in the constellation Ophiuchus. This system was approximately 19 light years from Sol.
The location of 36 Ophiuchi on 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 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", "A Quality of Mercy")
On stardate 1292.4, this system's position 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. Ophiucus 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")
In 3190, the location of Ophiucus was labeled on a star chart used by Commander Paul Stamets for tracking the movement of the Dark Matter Anomaly through the galaxy. (DIS: "The Examples")

Background information[]
A third named planet, Ophiucus IV, was mentioned in a deleted graphical design created for Star Trek: Prodigy.
Information on this system was derived from the episodes and films, from the reference works Star Trek: Star Charts and Stellar Cartography: The Starfleet Reference Library, and from real world sources. The reference works were used extensively in the creation of star charts seen in Star Trek: Discovery, Star Trek: Picard, Star Trek: Strange New Worlds, Star Trek: Prodigy, and Star Trek: Lower Decks. The real-world information added to the article was current as of 2025.
In the Star Trek: Star Charts (pp. 18, 19, and 44) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), the Ophiucus (36 Ophiuchi) system was in the Ophiucus Sector (Sector 008), which was the eighth sector explored by Earth starships. This system was colonized by Earth in the 22nd century and was a destination on the Earth trade routes. In the late 24th century, it was a Federation system.
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 current location of Ophiucus system in the Beta Quadrant was based on the most recent star charts seen in Star Trek: Strange New Worlds and Star Trek: Section 31.
