The angle between the perigee point and the satellite’s location measured in the direction of the satellite’s motion.
 A Eccentricity B Inclination C Polar Orbit D True Anomaly
Explanation:

Detailed explanation-1: -True anomaly is the angle between the perigee point and the satellite’s location (measured in the direction of the satellite’s motion). This value is constantly changing as the satellite moves in its orbit. True anomaly is 0 degrees at perigee, 180 degrees at apogee.

Detailed explanation-2: -The perigee is the point on the ellipse closest to this focus, the apogee, the point which is farthest. The true anomaly is the angle between a point on the ellipse and the perigee.

Detailed explanation-3: -Orbital inclination measures the tilt of an object’s orbit around a celestial body. It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object.

Detailed explanation-4: -In celestial mechanics, true anomaly is an angular parameter that defines the position of a body moving along a Keplerian orbit. It is the angle between the direction of periapsis and the current position of the body, as seen from the main focus of the ellipse (the point around which the object orbits).

Detailed explanation-5: -The mean anomaly is the angle… In celestial mechanics: Kepler’s laws of planetary motion. …the angle f, called the true anomaly, locates this point relative to the perihelion P with the Sun (or focus S) as the origin, or vertex, of the angle.
