A minimum-energy orbit to an outer planet consists ofputting a spacecraft on an elliptical trajectory with the departureplanet corresponding to the perihelion of the ellipse, orclosest point to the Sun, and the arrival planet correspondingto the aphelion of the ellipse, or farthest point from the Sun.(a) Use Kepler’s third law to calculate how long it would taketo go from Earth to Mars on such an orbit. (Answer in years.)(b) Can such an orbit be undertaken at any time? Explain.
