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 t...

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.
