Property Value

Eccentricity e can be calculated on the basis of semimajor axis a and semiminor axis b as follows:

e = sqrt(1 - (b / a)^2)

Referring to the following diagram, e can also be expressed as a / f, where f is the distance from the center of the ellipse to the center of mass of the central body:
