From SS13 Polaris
A gas giant, with a large number of moons. Captured asteroids, to be specific. Many of the asteroids are theorized to be the remnants of a moon of almost Martian size that was ripped apart by Kara, long ago. By now, a large number of these asteroids are being used by many different businesses, and some governmental infrastructure has been built. The most prominent asteroid installation is the NCS Northern Star, a general purpose colony owned and operated by Nanotrasen. The mid-atmospheric temperature of the gas giant is 150 kelvin (-108°C).
