2. Orbital eccentricityThe orbital eccentricity of an astronomical body is the amount by which its orbit deviates from a perfect circle, where 0 is perfectly circular, and 1.0 is a parabola, and no longer a closed orbit. It derives its name from the parameters of conic sections, as every Kepler orbit is a conic section.
