   The Earth completes one revolution (360°) around the Sun in about 365
   days.
   
   
   So, rate of revolution = 360°/365 days = 1° per day	
   (approx.)

   The eccentricity of an ellipse is a measure of how nearly circular the
   ellipse is, and is found by the following formula: 
   <blockquote>
	   eccentricity = c/a
   </blockquote>
   <blockquote>
	   where 
   </blockquote>
   <blockquote>
	   c = distance from the center C to focus F, and
   </blockquote>
   <blockquote>
	   a= distance from the center C to vertex V.<br />
   </blockquote>
   <blockquote>
	   In the given diagram, visualize a horizontal line through F1 and
   F2.  Then, we have,

   <blockquote>

   <blockquote>

   </blockquote>
   <blockquote>
	   <------ a -------->
   </blockquote>
   <blockquote>
	   Since c > 0.5a and c < a, the approximate eccentricity is c/a
   = 0.7  <br />
