The two stars of the Procyon system orbit each other with an average distance of 14.9 AU, equivalent to the distance of [[Uranus]] from the Sun, although the orbit is eccentric and carries the two stars as close as 9 AU and as far as 21 AU.  The secondary or companion star, Procyon B, isn't visible to the unaided eye and wasn't postulated to exist until 1840, through observances of the irregularities in the proper motion of the Procyon system.  Procyon B was first visually confirmed with a 36 inch refracting telescope in 1896 by John M. Schaeberle.<ref>http://www.solstation.com/stars/procyon2.htm</ref>
