The Esseles-class space station represents a space station design originating from the Alderaan Royal Engineers.
Its conceptualization involved constructing the station around a pre-existing moon, effectively utilizing the moon as the station's foundational structure. Urban areas, echoing those found on the subsequent Death Star battle stations, were distributed across the lunar surface and interconnected via transport tubes. A significant concentration of docking ports, communication arrays, and control centers was located at one of the moon's poles.
Due to the immense power generation within the station, specialized exhaust systems were implemented to dissipate the excess energy towards the surface.
Despite being identified as an "Esseles-class space station" in the specific entry for Hosk Station within The Essential Guide to Vehicles and Vessels, the Alderaan Royal Engineers entry in the Major Manufacturers section of the same book classifies Hosk Station as a "Delaya-Class Space Station".
