Planet Ten

From Memory Alpha, the free Star Trek reference

Planet Ten was a location in one of the holodeck simulations created by Lieutenant Tom Paris of the USS Voyager.

The simulation involved the rescue of slave girls from the planet. Paris said he left his days of participating in the program behind when he became a married man. (VOY: "Body and Soul")

Paris did not mention if the slave girls were of the oft-mentioned Orion variety.
