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 2.34500 ã 10^5 km and the planet has a radius of 4.050 ã 10^3 km and a mass of 7.45 ã 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 ã 10^-11 nâ·m^2/kg^2.
