The Moon is believed to have been created when a Mars-sized planetesimal (designated Theia by 20th century astrophysicists) collided with Earth in its early history.

The Orpheus Mining Colony, a lunar settlement in 2155.

The first known Moon landing was in 1969. Goddard Moonbase was established in 1997, with permanent settlements established over the next decade. (Star Trek Spaceflight Chronology; TOS novel: Strangers from the Sky)

In Star Trek Star Charts, the first lunar colony was establised in 2039.


As a major human settlement, Luna fell under Federation jurisdiction and protection. It was also a subdivision of United Earth.

In the 24th century there were over 50 million people living on the Moon. (Star Trek: First Contact) In Earth slang, people who lived on the moon were called lunar schooners. The lunar inhabitants were not fond of the term. (DS9: "Valiant"; Star Trek: Pendragon: "Children of the Burning Heart")


Starfleet Academy maintained an off-planet training facility on the Moon. (TOS novel: The Galactic Whirlpool)

By the early 23rd century, one of the tertiary educational institutions on Luna was the University of the Ocean of Storms. (TOS novel: The Final Reflection)

The diplomat Emanuel Tagore received a degree and/or taught here, per The Final Reflection.


One of the three monoliths that made up the Alien Obelisk Sol-Sirius Network was located on Luna. (Dimensional Prophecy of Zohar)


Per FASA RPG: Cadet's Orientation Sourcebook, Luna City was the capital of the Lunar colonies. Per Star Trek Star Charts, Tycho City was the capital.
The Vulcanis Lunar Colony is presumably not located on a moon of Vulcan, as it does not have any moons. Given its name, it may be on Luna.
