Explanation:
Detailed explanation-1: -Eccentricity is a measure of how non-circular the orbit of a body is. A particularly eccentric orbit is one that isn’t anything close to being circular. An eccentricity of zero is a circular orbit, between zero and 1 is elliptical, equal to one is parabolic, and greater than 1 is hyperbolic.
Detailed explanation-2: -A: Eccentricity is the measure of the “roundness” of an orbit. A perfectly circular orbit has an eccentricity of zero; higher numbers indicate more elliptical orbits.
