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