History and specifics[edit | edit source]
Omicron Ceti is on the fringes of Federation space, about two dozen light-years coreward of Kropasar, in the galaxy's Beta Quadrant. Its emissions include deadly berthold rays, rendering its otherwise eminently suitable planet Omicron Ceti III unsuitable for colonization. (TOS episode & novelization: This Side of Paradise, SCE eBook: The Future Begins)

On star charts, this system could be seen to be in the vicinity of Antares, Theta Bowles and Altair III. (TNG episodes: "The Wounded", "Yesterday's Enterprise", TNG reference: The Continuing Mission)
In the 2360s decade, this location was noted on a star chart showing deployment of Federation and Cardassian Union ships displayed in Captain Benjamin Maxwell's ready room aboard the starship USS Phoenix. (TNG episode: "The Wounded")
Alternate realities[edit | edit source]
