- Simpson's Planet
- 2003 UB13-III
This planet was home to a pre-warp civilization. And they were several sectors away from any other spacefaring government-held system; as such, the Romulan Star Empire laid claim to this planet and Homer Simpson was appointed ambassador from the Romulan Star Empire to this system.
