An illustration of the orbit of Procyon B about its primary. This is not what the orbit looks like from Earth, but is instead a "priveleged" perspective showing what it would look like from directly above--with of course, the primary treated as stationary instead of as in a mutual orbit about a barycenter. Periastron and apastron are labeled; the values in between are interpolated.
