There were at least five planets in this system, including the inhabited planet Cor Caroli V. (ENT: "Cold Front"; TNG: "Allegiance")
Stellar cartography[]
The Cor Caroli system was visible from Earth in the constellation Canes Venatici. It was approximately 100 light years (30.6 parsecs) from Sol.
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, 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. Cor Caroli was in or near to Federation space. (PIC: "Maps and Legends", "The Next Generation", "Disengage")
In 2401, the location of Cor Caroli was labeled on a star chart that was seen on the USS Stargazer's bridge viewscreen. The chart was used to show the location of the combined Starfleet-Borg armada and where it needed to go to face a galactic-level threat. (PIC: "Farewell")
Later that year, 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 3189, the location of Cor Caroli was denoted on a holographic star chart of the galaxy at Federation Headquarters. (DIS: "Die Trying")
In 3190, the location of Cor Caroli 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[]
This star system was only mentioned in writing.
Information on this system was derived from the episodes and films, the reference works Star Trek: Star Charts and Stellar Cartography: The Starfleet Reference Library, and 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.
Further information could be had from the Star Trek: Star Charts (p. 44) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"). In the 22nd century, the Cor Caroli system was a stop on a Vulcan trade route. In 2378, it was an independent 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)
