Alien Universe Planets: Guides To Moons And Planetoids

Xenomorph Prime, the Alien homeworld with giant biomechanical hive domes

The Alien franchise spans harsh moons, prison worlds, Engineer research sites, and rumored Xenomorph homeworlds - each location shaping how outbreaks begin and how survivors escape. This category collects guides to the planets, moons, asteroids, and planetoids that appear in the films, comics, novels, and games, from classic horror settings such as LV-426 and Fury 161 to newer colonies in expanded canon. Worlds marked with an LV survey code also sit on their own list. Many of these worlds tie into the Alien timeline, the mysteries of the Space Jockeys, and the prequel era covered in Prometheus Movies. When an outbreak spreads beyond a single landing zone, the results are covered in broader lore articles and in related categories such as Alien Universe Ships and Alien Lore.
