Detailed explanation-1: -Eccentricity. The value of Eccentricity (e) fixes the shape of satellite’s orbit. This parameter indicates the deviation of the orbit’s shape from a perfect circle. The value of eccentricity of a circular orbit is zero, since both a & b are equal.
Detailed explanation-2: -Orbital eccentricity describes the extent to which an orbit is elliptical or deviates from a perfect circle. A perfectly circular orbit would have an orbital eccentricity of 0. Values between 0 and 1 indicate an elliptical orbit, increasing numbers have a greater distance between the foci in the ellipse.
Detailed explanation-3: -Orbital Speed determines the orbit shape: Circular Speed. Escape Speed.
Detailed explanation-4: -The five parameters a, e, i, , completely define the satellite orbit in space and the sixth parameter M will define motion of satellite in orbit. a and e give shape of ellipse. i and relates orbital plane position with respect to earth’s equatorial plane.
