Procyon is a binary star system that consists of a white F-type main-sequence star, named Procyon A, and a faint white dwarf companion called Procyon B. Procyon A is currently in the last stage of its main sequence, showing signs of expansion as the last of its hydrogen core is used up. Though Procyon A is dying, the city-station Remus that orbits the binary pair is in no immediate danger, and as such continues to serve its vitally important role as a trading hub and academic beacon of interstellar civilization. Though technically within UNAC's jurisdiction, Procyon (like Sirius) is a shared system.


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