There are orbital cities in Earth orbit in the universe of Alternate Earth and the Local Solar System. They were all built thousands of years ago. When it comes to the politics on the planet below, these orbital colonies tend to be officially neutral in the conflicts between the Eurasian Dominate and the Pan-American Collective. These cities are huge, dwarfing even interplanetary cruisers (see spaceships in AELSS), and simulate Earth-like gravity by slowly rotating. The government of these orbital cities is jointly vested in a democratically elected General Assembly and a military-dominated Security Council.
