History and specifics[edit | edit source]
Light yellow clouds completely obscured the planet's surface. Its climate supported reptile lifeforms, grass, trees and moss. Surface features included hot springs, oceans, islands, low mountains, and quicksand.
In 2267, as the USS Enterprise explored Gamma galaxy, a sudden meteoroid storm just outside the orbital influence of Planet 656 damaged the ship's starboard nacelle. The starship landed on its desolate third moon to make repairs. Meanwhile, a probe from the ship located a transmitter station on 656, so James T. Kirk, Spock, Morton and Ferris took a closer look aboard shuttlecraft NCC-1701/3. The team encountered a gigantic reptile, and two of the crew fell through a sinkhole into an underground soil-stream.
The transmitter location turned out to be an active missile test site. Natives used a gravity lift to float the landing party away from a bomb blast and into caverns where they made first contact. (TOS comic: "Ground Zero")
