Answer :
Final answer:
Eccentricity is not one of Kepler's six orbital elements.
Explanation:
Eccentricity is NOT part of Kepler's six orbital elements. The six orbital elements are a (semi-major axis), e (eccentricity), w (argument of perihelion), i (inclination), and two additional angles to complete the description of the orbit in 3-space. Eccentricity defines the orbit's shape by the fraction obtained when dividing the distance between the center of the orbit and the sun by the semi-major axis.
