Cyrannus (TOS)

For other uses, see Cyrannus.

In "The Long Patrol", Starbuck refers to the Twelve Colonies of Man as being in the "Cyrannus Galaxy".

Opinion is divided whether the Colonies lie in the same galaxy as Earth, which—given numerous references (particularly in "Greetings from Earth") that the Earth sought after by the Colonials is our Earth—would have to be identical to our "Milky Way galaxy".

Opponents of such an identity can point to Commander Adama's clear statement in "Saga of a Star World", that Earth is located "In a galaxy similar to our own".

Proponents of the identity of the two galaxies argue that it is less improbable that the Fleet could traverse a large span of several thousand light-years within the Milky Way galaxy (which is approximately 100,000 light-years in diameter) than to make a journey from one galaxy to another (with distances in hundreds of millions of light-years). In the spin-off series Galactica 1980, the Fleet reaches 30 years after the Battle of Cimtar. The Original Series does not define the nature of propulsion nor does it provide sufficient information to determine if intergalactic travel is in use.
