Aerilon is primarily an agricultural world, known as the "food basket" of the Twelve Colonies.

Despite this, Aerilon is considered to be one of the poorest Colonies (TRS: "Dirty Hands"). Its capital city is Gaoth.


Aerilon's government provides little or no support for health care, education, or other social infrastructure services. However, Aerilonians accept police with broad powers to detain, imprison, and torture suspects.


Although Aerilon's soil is not very fertile and requires intensive cultivation to achieve plentiful harvests, it is primarily an agricultural world. The capital, Gaoth, started as a prairie town on intersecting cattle trails. Aerilon also has tylium mines, and Promethea, one of the larger cities on the planet, was founded as a mining town on the edge of a region known as the Badlands (Blood and Chrome, deleted scenes).


Fifteen people died when President Richard Adar, for reasons unexplained, sent the Marines to Aerilon (TRS: "Water").


While imprisoned on Galactica, Gaius Baltar talks extensively about Aerilon, confirming that it, not Caprica, was his birth world. He imitates the speech mannerisms of a stereotypical native, a farmer who likes to work with his hands, and "go down to the pub for a pint"[1] and have a fight at the end of the night. In doing this, Baltar puts on a strong raspy "Aerilon" accent [2] (TRS: "Dirty Hands").

Likewise, the musical and visual arts of Aerilon are informed by simple, harsh agrarian and working-class sensibilities.


Aerilon's prime educational institution, the University of Aerilon, is located in Gaoth. It is known for producing artisans, such as writer Mark Bailey whose works became well-known in YR42 (The Caprican: "The Bottom Five Backtalk Guests").

Its rival, the Promethea Agricultural and Mechanical (A&M), is based in the mining boomtown of Promethea (Blood and Chrome, deleted scenes).

  • The spelling of this colony is sometimes inconsistent in the Re-imagined Series' official cast and crew notes and episode content, in the same way that the Original Series had inconsistent spellings of "Centurion" and "Centurian". The colony is spelled "Aerilon" in the episodes "Home, Part I" and "The Son Also Rises" in official Colonial documentation, as well as placards from "Colonial Day" and various Season 4 episodes. Further research into this has lead Battlestar Wiki to choose the more prevalent spelling that appears on various props in the series, as well as spellings from the scripts: "Aerilon".
  • Socrata Thrace and Galen Tyrol pronounce the name as "Air-lon," while Baltar pronounces it "Air-e-lon".


  1. Baltar's use of the term "pub" and "pint" suggest that Aerilon's culture is reminiscent of that of the workers of Ireland, Scotland or England. Baltar's use of a unit of liquid measurement called a "jp" in the episode "Water" and "pint" suggests that the Colonials may have several units of liquid volume. The term "pint" is also a nickname for a glass of beer, which often is measured in Imperial pints.
  2. Actor James Callis, who normally speaks in his own native accent, adopted an accent similar to a Yorkshire accent for Baltar's "native Aerilon."
  3. This is alleged.
