Pollux IV was an uninhabited M class planet. This was the homeworld for the Greek gods and goddesses, an extinct warp capable humanoid species. It was the fourth planet in the Beta Geminorum planetary system. This system was located in the Mutara sector, which was a region of space in the Alpha Quadrant.
Pollux IV was a conventional M class planet with an oxygen-nitrogen atmosphere. The planet had an approximate age of four billion years. The nearest starbase was Starbase 12. (TOS: "Who Mourns for Adonais?")
In the distant past, this world was the home of a highly advanced civilization. They called their world Olympus. A group of Pollux IV inhabitants visited Earth in the 3rd millennium BC. They landed in the Mediterranean region and took residence on Mount Olympus. These aliens considered themselves to be gods and presented themselves as such to the primitive Humans. The worship of these aliens was the beginning of the Ancient Greek civilization and their deeds on Earth became the Greek classic myths. The aliens left Earth around 2700 BC to return to Pollux IV, when Humans lost interest in worshiping them. Absent worshipers, many of the Greek gods decided to end their own existence.
In 2267, USS Enterprise was surveying the Beta Geminorum system. James T. Kirk and his crew made contact with Apollo, the last of his race, who had waited for his worshipers to develop space travel and seek out their beloved god. The encounter resulted in the death of Apollo and the extinction of his species. (TOS: "Who Mourns for Adonais?")
In the 24th century, Pollux IV had become a tourist destination. A view of the surface of Pollux IV was depicted on several viewscreens on Deep Space 9's Promenade and Replimat, (DS9: "The Muse") advertising a visit to the "amazing ruins of Pollux IV". (DS9: "What You Leave Behind")
The location of Pollux IV was depicted on two Federation star charts. The location of Pollux IV in the Milky Way Galaxy was depicted on a large Federation star chart in 2293. In 2376, the location of Pollux IV was depicted on a star chart in astrometrics on USS Voyager in 2376. (Star Trek VI: The Undiscovered Country; VOY: "Child's Play")
