The point in lunar orbit nearest the surface of the moon is called perilune and the point farthest from the surface is called apolune.The Apollo 11 spacecraft was placed in an elliptical lunar orbit with the perilune altitude 110 km and apolune altitude 314 km ( above the moon).Find the equation of the ellipse if the radius of the moon is 1728 km and the centre of the moon is at one focus.
