Kaldor City, often shortened to just Kaldor, was one of three human colonies on Kaldor, established some point by the 29th century. (TV: The Robots of Death, PROSE: Corpse Marker) According to one account, Kaldor was in fact Japetus, one of the moons of Jupiter (PROSE: Legacy), but most other sources agree that it was a planet outside of Earth's Solar System. (AUDIO: Occam's Razor, COMIC: Crisis on Kaldor) In effect, the Founding Families (as the initial terraformers called themselves) became well established as the governing body of Kaldor by the 39th century.
