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. It is situated five days Slipspace travel from the Epsilon Indi system. Arcadia, a UEG colony world is located in this system. Laconia an uninhabited volcanic planet is also located in the system.
Arcadia was invaded by the Covenant in 2531 during which, Covenant Destroyer, the Radiant Perception crash landed on Laconia. 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.
