Midos V is a planet, located in the vicinity of Exo III and abundant in raw materials. During the mid-23rd century it was site of a small Federation colony.
In 2266, Roger Korby enlisted the Kirk android to arrange him transportation off Exo III to a nearby planet colony with proper raw materials to begin producing androids. Korby noted that there were several good possibilities among the USS Enterprise's next stops without diverting from the ship's route. In response, the android Kirk chose Midos V, noting that it was "an excellent choice" for Korby's needs. (TOS: "What Are Little Girls Made Of?")
