Procyon (UK: /?pro?si?n/ PROH-see-on), also designated Alpha Canis Minoris, is the brightest star in the constellation of Canis Minor; to the naked eye, it appears to be a single star, the eighth-brightest in the night sky with a visual apparent magnitude of 0.34. It is a binary star system, consisting of a white main-sequence star of spectral type F5 IV�V, named Procyon A, and a faint white dwarf companion of spectral type DQZ, named Procyon B.
The name Procyon comes from the Ancient Greek ??????? (Prokyon), meaning "before the dog", since it precedes the "Dog Star" Sirius as it travels across the sky due to Earth's rotation. In Greek mythology, Procyon is associated with Maera, a hound belonging to Erigone, daughter of Icarius of Athens.
