Sirius is a binary star system that consists of a blue-white A-type main-sequence star, named Sirius A, and a faint white dwarf companion called Sirius B. The city-station Romulus that orbits the binary pair is an important trading hub and shipbuilding bastion of the interstellar colonial network. Though technically within UNAC's jurisdiction, Sirius (like Procyon) is a shared system.


The Sirius binary system, like Procyon, is devoid of planets. However, Sirius is another vital hub in the deep space travel network as it hosts one of the two largest city-stations in known space, Romulus, which serves as one of the USSC's main bases of operation.   For more information, see the Wikipedia article on Sirius.
