Achernar, also known as Alpha Eridani, was an inhabited planetary system in the Beta Quadrant. It was a binary star system consisting of the stars, Achernar/Alpha Eridani A and Alpha Eridani B and at least two planets, including Alpha Eridani II. This planet, in the 2150s, was home to an United Earth colony. (TOS: "Wolf in the Fold"; PIC: "Maps and Legends")
Stellar Cartography
The Achernar system was located in the constellation Eridanus. This system was approximately 139 light years from Sol.
In 2259, the location of this star system was labeled on a stellar cartography chart seen on the USS Enterprise's ready room viewscreen. The system's symbol had a green color, indicating that it had an affiliation with the Romulan Star Empire. (SNW: "Spock Amok")
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 in 2401. Achernar was in or near to space claimed by the Romulan Free State. (PIC: "Maps and Legends", "The Next Generation", "Disengage")
This star system was only mentioned in writing.
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.
According to Star Trek: Star Charts (p. 66, "United Federation of Planets II") and Stellar Cartography: The Starfleet Reference Library ("Position of the Romulan Empire"; "Federation Historical Highlights, 2161-2385"), the primaries of this system were B-class stars. According to a map of the Romulan Empire – prepared by the Stellar Archive Artist Lsel Essik, from the Romulan Master Data Catalog, in 2366 – Alpha Eridani (Achernar) was identified as a Romulan system.
