Reach

This is an old gas giant that suffered an enormous impact when it was younger, being struck by a massive terrestrial planet. This not only knocked it on it's side, changing it's orbit, and skewed the orbit of most of it's moons, but it also introduced a massive quantity of heavy metals into the interior of the gas giant. Poking out of the clouds is a docking station that is connected, kilometers deep in the thick atmosphere, to an extensive mining complex which mines the semi-solid and liquid metals in the depths.
