Eccentricity_of_orbit

Astronomy.solar.Eccentricity_of_orbit(T)

Eccentricity of the orbit ellipse.

Eccentricity e is the ratio of half the distance between the foci c to the semi-major axis a: e=c/a. For example, an orbit with e=0 is circular, e=1 is parabolic, and e between 0 and 1 is elliptic.

The eccentricity of Earth’s orbit changes slowly with time.
