this modular orrery system can be used to simulate orbital mechanics in starmade. it includes the ability to stack up to achieve multiple orbits around the same object, program speed and direction, and leaves room to add needed mass enhancements.
how it works (with the bases visible):

docking large units at the point of their center of mass can create wonderful theatrical illusions of orbital mechanics. consider using this unit in tandem with a gyroscope to add criss-crossing satellites like the example asteroid/satellite pair seen here:
