45:0 The Local System Administration
45:0.1 The administrative center of Satania consists of a cluster of architectural spheres, fifty-seven in number—Jerusem itself, the seven major satellites, and the forty-nine subsatellites. Jerusem, the system capital, is almost one hundred times the size of Urantia, although its gravity is a trifle less. Jerusem's major satellites are the seven transition worlds, each of which is about ten times as large as Urantia, while the seven subsatellites of these transition spheres are just about the size of Urantia.
45:0.3 This entire system of fifty-seven architectural worlds is independently lighted, heated, watered, and energized by the co-ordination of the Satania Power Center and the Master Physical Controllers in accordance with the established technique of the physical organization and arrangement of these specially created spheres. They are also physically cared for and otherwise maintained by the native spornagia.
