The location of Wenselworld on a star chart

Wenselworld was a planet.

In 2293, the location of Wenselworld was labeled in the star chart for the "Operation: Retrieve" command briefing. The chart was from the Starfleet Command Intelligence Database. This star chart was seen in the office of the Federation President on Earth. (Star Trek VI: The Undiscovered Country, set artwork)

Many of these locations shared their names with the last names of crew who worked on the sixth film. This location was probably named after the production assistant Brian Wensel.
