Luna (also The Moon) is Earth's sole natural satellite. It is heavily populated, to the extent that the majority of the surface is covered with a contiguous belt of cities.
Luna was observed from Earth from ancient times. The first manned mission to the satellite took place in 1969, while Lunar Colonies were established in the late 21st century. By the late 24th century more than 50 million people lived on the Moon, in places like Tycho City, New Berlin and Lake Armstrong.
- “Surface Tension”: In early 2410, the lunar colonies come under attack during the Undine invasion of the Sol System. The R.R.W. Lleiset drives off the Undine ships attacking Luna.
- Luna is seen in the Sol System social map. As of Season 9, the moon has been moved further away from Earth and is no longer accessible by the player. Its position now more closely resembles the Moon's real-life orbit.
- It has been mentioned in Deep Space Nine that the inhabitants of Luna do not refer to the Moon as such. The use of "Luna" in the Star Trek universe mostly helps to distinguish the Moon from other celestial satellites.
