For the planet in the original series continuity, see Caprica (original series).

Caprica is a planet in the Cyrannus star system, orbiting the star, Helios Alpha. It is the twin planet of Gemenon, which shares its orbit. Caprica was attacked by a Cylon strike force at the start of the Second Cylon War and most of its population was destroyed. After a brief colonisation effort by the Cylons, it was abanoned entirely. It is named after the Capricorn tribe who resided on Kobol, though its citizens may not have been affiliated with that tribe.[note 1]


Caprica was possibly the first planet colonised by the Twelve Tribes after the settlement of Gemenon. In the first centuries of expansion, Caprica lagged behind Virgon and Leonis, which held colonial empires that dominated the region. When the two empires exhausted one another in a protracted interplanetary war, Caprica began its rise as the new dominant power. On the eve of the First Cylon War, Caprica became the undisputed centre for culture, art and education, and saw heavy migration from people from various planets seeking to start a new life. At the start of the war, Caprica was federated into the United Colonies of Kobol, and hosted its president in Delphi.

Forty years after the Armistice, the Second Cylon War began with a coordinated strike of all twelve planets by orbiting Cylon Baseships. Caprica City was destroyed by a MIRV strike, though other prominent cities such as Delphi were left intact as Cylon landing parties wiped out retreating civilians. For the next several months the Cylons took part in colonisation efforts and cleaned up debris to restore the cities to their pre-war state. Less resistant to the radiation on the planet after the attacks, Caprican resistance fighters spent a great deal of time looting isolated facilities for medical supplies. The few surviving fighters were evacuated by marines as part of a Raptor mission ordered by Admiral William Adama, which coincided with the abandoning of Cylon colonisation thereby leaving the planet uninhabited.


Central in the Trojan orbit, Caprica used to be a beautiful blue-green world with the perfect climate. The colony had rolling hills, pleasant lakes, and deep forests. The cities were heavily populated, but it never seemed that way. Glittering silver towers spiked through bustling open air markets and plazas. Parks, rivers, and waterfalls were everywhere. So comfortable were Caprica's cities that people rarely paid attention to the steady lines of vehicles streaking past overhead.

Culture​​ Edit

The city of Delphi housed all three branches of government and hosted the biggest corporations and universities in the system. The city had replicas of the Forum, Temple, and Opera House trying to replace the originals left behind on Kobol. The Museum of the Colonies displayed many original artifacts from the lost home world.

Further notes Edit

  • Much information on Caprica was added into the series lore for the show Caprica. Writer Jane Espenson also collaborated in the creation of mapping the Cyrannus star system with the positions of each planet along with explaining their histories. The factoids themselves quasi-canon, existing in a preliminary level where they are canon unless contradicted by new information.[1] However, as there was no second season of Caprica to contradict them, they stand.



  1. The history of the Cyrannus system suggests there is no direct link between the planets and the tribes they were named after. Colonies such as Caprica; Picon and Virgon were settled by the same people. Aquaria meanwhile was founded as a scientific outpost rather than a settlement for the Aquarius tribe.
