Upsilon Xi III

Upsilon Xi III was a habitable planet, the third in the Upsilon Xi star system.

In the late 2270s, the USS Enterprise (NCC-1701) stopped off at Upsilon Xi III so that the crew could enjoy shore leave on the planet. While many of the crew took the opportunity to visit the planet, Lieutenant Commander Nyota Uhura remained aboard ship. (SS TOS (Under Twin Moons))
