The weight of an astronaut on the surface of planet Z, due only to its gravitational pull, is equal to 389 N. If moved to a distance equal to 10 × 1,86 4 mi above the surface of the planet, the value of the weight is changed to 24.31 N . What is the mass of planet Z if the mass of the astronaut is equal to 75.0 kg ? ( G = 6.67 × 10 -11 N ∙ m 2 / kg 2 )
