An undiscovered planet, many lightyears 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 2.105 X 105 km and the planet has a radius of 3.850 X 103 km and a mass of 6.55 x 1022 kg, how long (in days) does it take the moon to make one revolution around the planet? The gravitational constant is 6.67 X 10'11N-rn2/kg2. /' TOOLS x10y
