2. 
   eccentricity
   A value that defines the shape of an ellipse or planetary orbit. The eccentricity of an ellipse (planetary orbit) is the ratio of the distance between the foci and the major axis. Equivalently the eccentricity is (ra-rp)/(ra+rp) where ra is the apoapsis distance and rp is the periapsis distance.

6. 
   Eccentricity
   The measure of how non-circular an object's orbit is. 0 = a perfect circle; any figure between 0 and 1 = an ellipse; 1 = a parabola; any figure greater than 1 = a hyperbola. Eccentricity may sometimes be expressed as a percentage. Eccentricity may be calculated by dividing the distance between the two foci of the ellipse and the length of the major axis of the ellipse.

7. 
   Eccentricity
   The eccentricity of an ellipse (orbit) is the ratio of the distance between its focii and the major axis. The greater the eccentricity, the more 'flattened' is the ellipse.

11. 
    Eccentricity
    Definition (advanced level) A conic section can be described as the locus of a point P whose distance PS from a fixed point S is in some fixed ratio to its perpendicular distance PN from a fixed line. This fixed ratio is then called the eccentricity of the conic. <br /> For an ellipse, it is a measure of how much it differs from a circle.
