Ganymede

From Cowboy Bebop: Space Cowboy

Ganymede, Jupiter's largest moon was perhaps the easiest hunk of rock to terraform in the solar system. Its atmosphere already containing much oxygen, and already containing an abundance of water, it served as a near-ideal candidate for colinization, which led to the thriving, though small cities that cover it today. Though it took the retrofitting well, the surface of Ganymede was still covered almost completely in water. This lead to local wildlife, such as the popular delicacy, the Ganymede sea rat developing and thriving while man kind struggled to produce land to establish itself on.

The capital of the human establishments on the planet is the large La Fin City, which is divided into the sectors of Main, Public, and Business. Carson city also exists in close proximity to La Finn. This city is rumored to be the headquarters of the main interplanetary policing authority, the Inter-Solar-Sytem-Police (ISSP).
