Daran X was a planet, the outermost tenth planet in orbit of the Daran star system in Federation space, in sector 54R at coordinates -127.5,-139.2,-19.7 (or 3.88S 4.93E) in the galaxy's Alpha or Beta Quadrant. A nondescript world, Daran X had two moons and was not known to have any major inhabitation by humanoid lifeforms. (ST reference: The Worlds of the Federation) Daran X was only seen as part of the system diagram, and is only notable due to the presence of moons.
