The Procyon system, (pronounced /'proʊsɪən/) also referred to as α CMi or Alpha Canis Minoris, is a binary star system situated 11.41 light years from the Sol System. The system consists of a white main sequence star of spectral type F5 IV-V, named Procyon A, and a faint white dwarf companion of spectral type DA, named Procyon B. Its closest neighbor is Luyten's star, 1.11 ly away. Arcadia, a former human colony world is located in this system.
History
Arcadia was invaded by the Covenant in 2531.[1] However, they left the system soon after without glassing the planet. A small number of human colonists remained on the planet, which was eventually glassed when the Covenant returned in 2549.
