Location of Procyon

Procyon, easily the brightest of the stars of Canis Minor, lies near the centre of its small home constellation.

Possible Appearance of Procyon

Possible appearance of Procyon: the small but massive White Dwarf component draws tendrils of matter from its much larger but less dense yellow companion.
