Zytchin III was the inhabited third planet in its system. This world was once visited by Starfleet officer Jean-Luc Picard, who spent four days on the planet. He told Beverly Crusher that he enjoyed his stay. When Dr. Crusher tried to recommend a rest leave for him in 2366 and reminded him of Zytchin, Picard claimed he had lied about his fondness for the place. (TNG: "Captain's Holiday" ) This planet was only mentioned in dialogue.
