Explanation
To solve this problem, we need to understand the relationship between the kinetic energy and the position of a planet in an elliptical orbit.In an elliptical orbit, the velocity of the planet is highest at the perihelion (closest point to the Sun) and lowest at the aphelion (farthest point from the Sun).Given:• AC is the major axis of the ellipse.• S is the position of the Sun.• B is perpendicular to AC at S.Let's analyze the positions:
