GRAVITY FIELD IN EXTERNAL PARTS OF THE SOLAR SYSTEM

Abstract

Taking into account the gravitational perturbations from the center of the galaxy and using the catalogue closest to the Sun, stars modeled surfaces of equal gravitational potential energy fields in the outskirts of the solar system. Constructed three-dimensional model of equipotential surfaces in the vicinity of the solar system. It is shown that for certain values a constant of the energy the Sun is within the common equipotential surface Toliman, Sirius and Procyon. The solar system is a combination of many celestial bodies, held by gravity. About 99:8% of the mass falls on the Sun. Therefore, almost all of the Sun deter- mines the motions of the solar system. Move around the Sun eight major planets with satellites, dwarf plan- ets, asteroids, comets, Kuiper belt objects, meteoroid and gas-dust complexes. With the sun's surface con- tinuously flows expire plasma - the solar wind. With increasing distance from the Sun, its density and veloc- ity continuously decrease. At some distance the solar wind mixes with the interstellar medium. This bound- ary is called the heliopause. At present, it is assumed that it is at a distance of 119 AU from the Sun (NASA, 2012). With increasing distance from the center of the so- lar system, the attraction of the sun diminishes. To describe the boundaries of the space within which, it is advisable to take the main attraction of the sun, apply the concept of the incidence (Chebotarev, 1965; Balk, 1965). When moving inside the sphere, acceleration, directed towards the Sun is considered the main, all other speed - disturbing. The radius of incidence of the sun relative to the galactic center is estimated at 60 000 AU (Chebotarev, 1965). The area of the cir- cumsolar space that lies beyond this distance is called the outskirts of the solar system. In this region the gravitational acceleration toward the Sun is compara- ble to the gravitational acceleration to other celestial
