Procyon (α CMi, α Canis Minoris, Alpha Canis Minoris) is the brightest star in the constellation Canis Minor. To the naked eye, it appears to be a single star, the seventh brightest in the night sky with a visual apparent magnitude of 0.34. It is actually 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 DA, named Procyon B. The reason for its brightness is not its intrinsic luminosity but its closeness to the Sun; as determined by the Hipparcos astrometry satellite, it lies at a distance of just 11.46 light-years (3.51 parsecs), and is therefore one of our nearest stellar neighbours. Its closest neighbour is Luyten's Star, about 1.12 ly (0.34 pc) away, and the latter would appear as a visual magnitude −7 star in the night sky of a hypothetical planet orbiting Procyon.
Procyon forms one of the three vertices of the Winter Triangle, along with Sirius and Betelgeuse.
Procyon A has a stellar classification of F5IV-V. The effective surface temperature of the star is an estimated 6,530 K, giving it a white hue. It is 1.4 times the mass, twice the radius, and 6.9 times more luminous than the Sun. Procyon A is bright for its spectral class, suggesting that it is a subgiant that has nearly fused its core hydrogen into helium, after which it will expand as "burning" moves outside the core. As it continues to expand, the star will eventually swell to about 80 to 150 times its current diameter and become a red or orange color. This will probably happen within 10 to 100 million years.[citation needed]
