The Babylon 5 television show and associated television movies created a fictional universe containing a large number of planets, moons, and other locations.
A prevalent setting in the fictional universe are planets and other locations that exist in normal space. There is at least one scene that explicitly documents the real world location, the Milky Way galaxy, as portrayed in the lower image to the right. Most references are implicit.
Within the fictional galaxy are at least one quadrant and grid or sector, and stars containing planetary systems. Several other sectors and quadrants are referenced in the fictional universe, but are not listed here because they are neither used as settings, nor do they have real world references.
The planet Centauri Prime, which is sometimes described as orbiting the star Zeta Tucanae, is the homeworld of the fictional species Centauri. The planet is used as a secondary setting in many episodes and movies.
Note that creator Straczynski has explicitly stated that Centauri in this context is not a reference to Alpha Centauri or Proxima Centauri.
The planet Chi Draconis A is the homeworld of the Minbari fictional species. The planet is used as a secondary setting for many scenes, including a civil war.
On the fictional planet Deneb 4 (also written Deneb IV) is an outpost/colony. It is the fourth planet from the star Deneb, which is located 1600 light years from Earth. It is only used as a reference, not as a setting.
It is mentioned twice in the fictional universe, hence not much information about the fictional reference is available:
As a real world reference, Deneb is a bright star, and if a habitable planet did in reality orbit it, it would need to do so at a distance of about 258 AUs, over eight times Neptune's distance from Sol. Any closer and liquid water would not be able to exist.
The Drazi homeworld is located in the Drazi system. It is the primary setting in one episode.
Grid Epsilon is the setting chosen by creator Straczynski as the main area of space for the fictional universe Babylon 5. It was named after the GEnie online forum (message base, known as a "RoundTable" on GEnie) where Straczynski originally communicated with fans starting in 1991, two years before the pilot telefilm aired. The precise coordinates of Grid Epsilon "470 by 18 by 22" are named for the specific GEnie forum, known in the early 90's on GEnie as "470/18/22" (Page 470, CAT 18, Topic 22).
The Epsilon Eridani (ε Eridani) system, situated 10.5 light years from Sol, is located in a fairly central position between the galactic powers. The position makes it a perfect, albeit second, choice for the Babylon 5 space station. The original location was abandoned after Babylon 4 disappeared in the region (see Sector 14, below).
