Components

Stellar system

This was a trinary star system. It was organized into a single star system and a binary star system.

The primary Dalim (the proper name for Alpha Fornacis A) was located in the single star system. This was a F-type dwarf.

Bound by gravity to this system, Alpha Fornacis Ba and Alpha Fornacis Bb were the companions to Dalim and orbited each other in the binary system. They were a G-type dwarf and a white dwarf, respectively.

History

When the Venari Ral laid Omega-47 mines around the core of Federation space in 3196, this system was within the enclosed region. (SA: "300th Night", "Rubincon")

Stellar cartography

The Alpha Fornacis system was visible from Earth in the constellation Fornax. It was approximately 46 light years 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 3196, this system's position was labeled on a Federation star chart which was displayed on the main viewscreen of the USS Athena bridge. (SA: "Ko'Zeine")

Later that year, In 3196, during the Omega-47 crisis, the location of Alpha Fornacis 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. (SA: "Rubincon")

This star system was only mentioned in writing.
Information on this system was derived from 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.
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)
