Beta Geminorum system

The Beta Geminorum system, also known as the Pollux system or 78 Geminorum system, was an inhabited planetary system in the Beta Quadrant

The first magnitude star Pollux was the closest red giant to Sol.

This was the home system of the extinct Greek gods. (TOS: "Who Mourns for Adonais?"; ENT: "Cold Front")

Components

Stellar system

This was a single star system. The primary Pollux (the proper name for Beta Geminorum) was a K-type red giant.

Planetary system

In this system, there were at least five planets. The planets Pollux V and Pollux IV were in the habitable zone of this system. The latter planet was the homeworld of the extinct Greek gods. (TOS: "Who Mourns for Adonais?"; ENT: "Cold Front")

History

The Beta Geminorum system formed over 4 billion years ago. (TOS: "Who Mourns for Adonais?")

In 2257, during the first Federation-Klingon War, this system was occupied by the Klingons. (DIS: "The War Without, The War Within")

In 2267, the closest starbase was Starbase 12. (TOS: "Who Mourns for Adonais?")

When surveying Pollux V and the rest of the Beta Geminorum system in 2267, the USS Enterprise detected a statistically unexpected absence of intelligent life at first. However, the ships's crew soon encountered Apollo, the last member of his species of ancient intelligent humanoids, on Pollux IV. (TOS: "Who Mourns for Adonais?")

Stellar cartography

The Beta Geminorum system was visible from Earth in the constellation Gemini. This system was approximately 34 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 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")

The Explored Galaxy

"The Explored Galaxy"

In 2293, the location of Beta Geminorum in the Milky Way Galaxy was labeled in a star chart that was in Captain James T. Kirk's quarters aboard the USS Enterprise-A. (Star Trek VI: The Undiscovered Country, okudagram)

In 2371, the location of Beta Geminorum was labeled on a star chart Data and Picard were studying in stellar cartography on the USS Enterprise-D. (Star Trek Generations, okudagram)

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. The Pollux system was in or near to Federation space. (PIC: "Maps and Legends", "The Next Generation", "Disengage")

In 2401, this system's position was labeled (Pollux) 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")

Background information

Michael Okuda, who created the star chart "The Explored Galaxy", depicted Beta Geminorum and Pollux as two distinct stars, even though they were established to be synonymous in "Who Mourns for Adonais?".

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.

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 Beta Geminorum 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.
