The Paxan homeworld was an inhabited planet. It was the adopted homeworld of the xenophobic Paxan species in the 24th century.
This was the only planet in a T-Tauri type star system located within the Ngame Nebula. This planet was located somewhere in the Alpha or Beta Quadrant.
The planet was a protoplanet and uninhabited. The Paxans claimed and terraformed it for colonization, making it a Class M planet. Its location was ideal for concealing their whereabouts. The Paxans also set up a trap involving a wormhole near the planet in order to goad visiting ships into a scenario where they would move away without investigating.
Ironically, the unusual nature of the planet prompted the USS Enterprise-D to investigate it in 2367. The Paxans' trap did not work with the positronic brain of Commander Data; however, the two parties cooperated to fix the situation, and Starfleet eventually did not learn of the significance of the planet.
