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 2.450 x 10^5 km and the planet has a radius of 3275 km and a mass of 6.25 x 10^22 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^-11 Nm^2/kg^2.
