GRAVITATIONAL ENERGY OF A SYSTEM OF CELESTIAL BODIES

Abstract

The article considers the characteristics of the gravitational field of a system of celestial bodies. The concepts of tension and potential characterizing the gravitational field are revealed. The central field of the point mass was considered and its characteristics were given. The similarities and differences between celestial bodies and the gravitational fields of a point mass were studied using the comparison method. It is proved that for any system of bodies their gravitational energy is equal to a negative value. It is proved that the total energy of the system is equal to the sum of gravitational and kinetic energy. The laws of gravitational energy or binding energy of bodies forming an isolated system were studied. The equations of gravitational energy of a system of material points and a spherical celestial body with a constant density are generalized. The solar system and the gravitational energy of its constituent celestial bodies are investigated.
