LV Planets: Life Viable Surveyed Worlds

The LV prefix is read as Life Viable, a survey mark for a moon or planet that can hold human life. The number is a serial from company charts, the same kind of list that named 300 surveyed worlds in Aliens. This list covers those coded rocks, from LV-426 and LV-223 around Calpamos to later numbers such as LV-178, LV-363, LV-895, LV-921, and LV-991. Prison worlds and named colonies without an LV code stay with the wider Alien universe planets.
