The Cursa system was visible from Earth in the constellation Eridanus. This system was approximately 90 light years from Sol.

In 2256, its location was labeled on the star chart "Alpha/Beta Quadrant Overview" in the ready room aboard the USS Discovery. (DIS: "Magic to Make the Sanest Man Go Mad")

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

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

In 3196, during the Omega-47 crisis, the location of Gacrux (Gamma Crucis) was depicted on star charts and readouts used across several locations on the USS Athena to locate, monitor, and respond to the Omega-47 mines laid by the Venari Ral. This system was outside the affected region. (SA: "300th Night", "Rubincon")

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, Star Trek: Lower Decks, and Star Trek: Starfleet Academy. The real-world information added to the article was current as of 2026.
Further information on this system could be had from the Star Trek: Star Charts (p. 63) and the Stellar Cartography: The Starfleet Reference Library ("Stellar Cartography", pp. 27, 30; "Federation Historical Highlights, 2161-2385"). The Cursa 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.
