Explanation:

Yes, since no energy is added or removed from the Sun + planet system, its energy is conserved no matter what the shape of the orbit, so KE + PE = constant. The force of gravity does no work on a satellite in circular orbit since the force is always perpendicular to the planet's direction of motion.
