Jaxxa Prime was the prime planet in its star system. It was home to a species of rectal insectoids.
During their reunion in 2380, K'orin reminisced with Beckett Mariner about a commander they met there who didn't believe her about rectal insectoids. Mariner laughed about the incident, recalled, "Yeah, I got chewed out, but his ass got chewed up." (LD: "Envoys")
This planet was only mentioned in dialogue.
