Location and specifics
Lactra was located in the vicinity of Epsilon Scorpii, a Beta Quadrant star. A distortion layer in the Lactran atmosphere was difficult to scan through. Gravity was close to Earth standard. (TAS - Log Eight novelization: The Eye of the Beholder)
Six weeks later the crew of the USS Enterprise located Ariel abandoned in orbit and beamed down a search party. Enterprise and Ariel officers were caged in a Human zoo habitat in the Lactran city. (TAS episode: "The Eye of the Beholder")
Three Lactrans left the planet aboard the Enterprise on a quest to capture a continent-sized jawanda for the zoo. The starship returned two to three months later with one of these cosmozoans and placed it in a polar orbit around Lactra VII. (TAS - Log Eight novelization: The Eye of the Beholder)
