Lunasphere Artemis was an artificial dome habitat on Luna, Earth's primary satellite. The dome was made of transparasteel. The lunasphere contained the Brobdingnagian forests, with towering trees over two hundred meters tall. The polarized dome was almost fourteen hundred meters tall, and a popular site for recreational fliers.
In 2379, the Federation hosted a diplomatic cocktail hour in the lunasphere. Artificial gravity was added to the meeting hall, the only place within the dome. Federation President Min Zife met with various Ambassadors at the function, including Derro of Ferenginar, T'Kala of Romulus, Zogozin of Gorn, and K'mtok of Qo'noS. (TNG novel: A Time to Heal)
