The planet Terra is home to the Terran Nationalists and the Eastern Alliance. The Eastern Alliance would have eliminated the Nationalists in a nuclear attack if not for the intervention of Apollo and Galactica. Despite hopes that Galactica had finally reached its destination, it is revealed that Terra is not Earth (Experiment in Terra).
Colonists from Terra founded the Lunar Colonies. Galactica first encounters "Earthlings" when they discover a ship from the Lunar Colonies. The people aboard were attempting to flee the influence of the Eastern Alliance by travelling to Paradeen (TOS: "Greetings from Earth").
The Link to Earth
In the episodes "Greetings from Earth" and "Experiment in Terra" there are clues pointing to the people of Terra being descendants of the Thirteenth Tribe:
- The names of Terrans are Earthling names (e.g. Michael, Brenda), with a first and last name that is consistent with a great deal of Earth's cultures.
- Terra is Latin (and Gemonese) for Earth.
- The Terrans have never heard of centons as the Terran Michael asks Apollo what a centon is.
- Shots of Terra in "Experiment in Terra" look conspicuously like Earth herself, notably the North American continent.
