The planet Saturn presents various appearances to the earth, consequent upon the 

 relative positions of the two bodies. Thus, while the planet traverses one part of its 

 orbit, the southern side is presented to us, and during its passage through another 

 portion of its orbit, the northern side is seen. Twice in every revolution, or once 

 in every fifteen years, the plane of the ring intersects the ecliptic, and its edge is 

 then seen as a fine line across the body of the planet; at other parts of the orbit 

 the ring becomes more or less open as the planet recedes from, or approaches, the points 

 of intersection.
