The Ji Dian Station consists of a core that is 23 levels in length and a docking ring at the fifth level, which has eight docking bays and eight exterior docking stations. Two retractable refining and processing silos lie around the outer perimeter (previously there were three but one was launched).

The most recent census numbers show that Ji Dian is capable of housing as many as 1000 people. Currently, it has a crew complement of 202 (23 officers and 172 crew) and 182 acknowledged civilian residents. The number of people below decks is unknown, but estimates range from 60 to 400.

Ji Dian Station is the farthest body orbiting the gas giant Heinlein. It shares Heinlein?s orbit with four terraformed moons. They are, from closest to farthest, Triumph, Paquin, Lazarus, and Silverhold.
