Explanation:
Detailed explanation-1: -Eccentricity, which together are the basic measurements of the size and shape of the orbit’s ellipse (described in Chapter 3. Recall an eccentricity of zero indicates a circular orbit).
Detailed explanation-2: -[v(t)] True anomaly is the geocentric angle between perigee direction and satellite direction. The sum of the true anomaly and the argument of perigee defines the Argument of Latitude. Notice that for a circular orbit (e=0) the argument of perigee and the true anomaly are undefined.
Detailed explanation-3: -The Moon’s orbit around Earth is elliptical. The point of the orbit closest to Earth is called perigee, while the point farthest from Earth is known as apogee.
