LCARS planet []
LCARS planet
A graphic depicting this unidentified planet appeared in USS Voyager's library computer in 2375. (VOY: "Drone")
Planet between Delta and Alpha Quadrants []
A planet
This planet, illuminated by a nearby star, existed in 2374 partway between the Delta and Alpha Quadrants. (VOY: "Hunters")
The world was shown in a somewhat impressionistic montage of a transmission traveling to USS Voyager from its home.
Planet used by Metrons []
The surface of the planet
This planet was located within 1,000 cubic parsecs of space from the USS Enterprise's position just outside of 2466 PM. Its surface was populated by scrub bushes, rocks, and mineral deposits.
After the Federation and Gorn came into conflict over Cestus III in 2267, the Metrons prepared this planet with a suitable atmosphere for both combatants, and transported Starfleet Captain James T. Kirk and a Gorn captain there to resolve the dispute. (TOS: "Arena")
In "Arena", although the Metrons refer to this place as a planet, Kirk once describes it as an asteroid.
Star Trek Online's expansion "Agents of Yesterday" gave it the name "Edren IV". [1](X) Edren IV (β) was a world created by the Metrons for this conflict. It was located in the Edren (β) star system, also known as the Metron system, at coordinates 2466 PM. This was the home system of the Metrons, and the capital system of their Metron Consortium. The system was located in the Celes sector (β), a region of space in the Beta Quadrant.
Q's planet []
The surface of "Q's planet"
In 2364, Q brought the crew of the USS Enterprise-D to the surface of a desolate planet in an unknown location. Data hypothesized that, due to Q's powers, the planet and its twin moons might not have existed at all. The surface was desert-like with rocks, and assumed by Data to be "obviously a class M world". No animal or plant life was found on the planet, and its sky was green. (TNG: "Hide And Q")
