In order better to map the surface features of the Moon, a 311-kg imaging satellite is put into circular orbit around the Moon at an altitude of 1.43 × 102 km. Calculate the satellite's kinetic energy, gravitational potential energy, and total orbital energy. The radius and mass of the Moon are 1.74 × 103 km and 7.36 × 1022 kg.
