Masses of Celestial Bodies

摘要

The masses of all celestial bodies are determined based on the theory of world gravity theories. The author of this theory describes the Newton equations [1]. Newton presented the gravitational interaction of two bodies in the equation: 1 2 п 2 G m m F r ? ? ? (1) Where, 1 2 m m, the masses of bodies 1 and 2, respectively, G = 6.672 10-11 Nm 2 /kg2 is the gravitational constant, r is the distance between the bodies. On the surface of the earth, this equation has the form: F gm n ? (2) m=the mass of the body, on the surface of the Earth g=free fall acceleration Fn=the force of gravity From the known values of the acceleration of free fall g and G, the Earth's mass Me=5.97 × 1024 kg was determined [2]. The average density of its substance is 5500 kg/m 3 , which varies from values in the earth's crust-2200 kg/m 3 to 13100 kg/m 3 in the core of the Earth [3].
