The Acamar system was an inhabited planetary system in the Beta Quadrant. The system consisted of the primary Acamar and at least three planets, including Acamar III. This planet was the homeworld for the space-faring Acamarians. (TNG: "The Vengeance Factor"; DIS: "Magic to Make the Sanest Man Go Mad")
Background information Edit
This star was mentioned as a destination in Pocket TOS: The Wounded Sky, and (with the "Theta Eridani" name) in Marvel TOS: Experiment in Vengeance! where the second planet in this system had a moon named Mycena. Neither of these depicted the existence of the native Acamarian civilization on the third planet.
