Penal colony (Earth-7149)

Penal colonies are colonial territories, be them planets, moons or space stations used only as correctional facilities for convicts. In penal human colonies, prisoners are expected to labor in mines and industrial facilities for materials. Prison ships are vessels designated to transport prisoners to penal colonies. Phobos, Mars' largest natural satellite, is home to a massive penal colony, while Fiorina 161, in the Neroid system, is home to the Fiorina 161 Class C Work Correctional Unit, a massive prison that exclusively housed men afflicted with double-Y syndrome.
