The maximum distance from the Earth to the Sun (at aphelion) is 1.521 × 1011 m, and the distance of closest approach (at perihelion) is 1.471 × 1011 m. The Earth’s orbital speed at perihelion is 3.027 × 104 m/s. Determine (a) the Earth’s orbital speed at aphelion and the kinetic and potential energies of the Earth–Sun system (b) at perihelion and (c) at aphelion. (d) Is the total energy of the system constant? Explain. Ignore the effect of the Moon and other planets.
