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 2.46500 × 105 km and the planet has a radius of 4.400 × 103 km and a mass of 4.15 × 1022 kg, how long (in days) does it take the moon to make one revolution around the planet. The gravitational constant is 6.67 × 10-11 N·m2/kg2.
I get 66.76 days, but the system says wrong
