1.

a. The quality of being eccentric.

b. Deviation from the normal, expected, or established.

2. An example or instance of eccentric behavior.

3. Physics The distance between the center of an eccentric and its axis.

4. Mathematics The ratio of the distance of any point on a conic section from a focus to its distance from the corresponding directrix. This ratio is constant for any particular conic section.

eccentricity  (ksn-trs-t)

1. A measure of the deviation of an elliptical path, especially an orbit, from a perfect circle. It is equal to the ratio of the distance between the foci of the ellipse to the length of the major axis of the ellipse (the distance between the two points farthest apart on the ellipse). Eccentricity ranges from zero (for a perfect circle) to values approaching 1 (highly elongated ellipses).

2. The ratio of the distance of any point on a conic section from a focus to its distance from the corresponding directrix. This ratio is constant for any particular conic section.
