Callisto

Callisto was an ice-covered moon of Jupiter, and the third-largest moon in the Solar System behind Ganymede and Titan.
Callisto was terraformed in the 21st century, though only barely, as it was a cold and desolate natural satellite. Existing on the outskirts of inhabited space, Callisto had become a refuge for illegal groups and trades, and the population was almost entirely male. As such, there were also very few families or children.
The moon underwent a financial depression in 2171
