Research Station

The ρ-class research stations are listed in the classification system of Imperial worlds, but are not worlds themselves. Some are based in orbit around planets or on asteroids, or on worlds themselves, such as dead worlds or death worlds. Types of research stations include actual laboratories, as well as surveillance posts for defensive purposes. Populations range from 100 to 500,000, and tithes are typically Aptus Non.
