An undiscovered planet, many light years from Earth, has one moon which has a nearly circular periodic orbit. If the distance from the center of the moon to the surface of the planet is 2.24000 x 105 kilometer and the planet has a radius of 3.550 x 103 kilometer and a mass of 5.20 x 1022 kilogram, find how long does it take the moon to make one revolution around the planet? The gravitational constant is 6.67 x 10-11.
