Question

The maximum distance from the Earth to the Sun (at
aphelion) is 1.521 3 1011 m, and the distance of closest
approach (at perihelion) is 1.471 3 1011 m. The Earth’s
orbital speed at perihelion is 3.027 3 104 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.
