A very prominent and nearby star, Procyon is not only the fifth brightest star in the sky,
but is also just eleven light years from the Sun. The primary star is an F-type subgiant,
but this has a tiny companion: a White Dwarf star.
Procyon, easily the brightest of the
stars of Canis Minor, lies near the centre of its
small home constellation.
Possible appearance of Procyon: the small but massive White Dwarf component draws
tendrils of matter from its much larger but less dense yellow companion.
