The Esseles-class Space Station was a space station-design made by Alderaan Royal Engineers.
It was designed to be built around an existing moon and use the satellite as a basis for the station itself. City sprawls, similar to the ones on the later Death Star battlestations, were spread across the moon's surface and linked by transport tubes. A large cluster of docking facilities, communications systems and control towers was centralized on one pole of the moon.
The amount of power generated in the station's interior was so high, specialized venting systems were installed to bleed it off, up to the surface.
