FIELD: astronomic engineering. SUBSTANCE: method involves rotating base with a body imitating planet by means of a driving unit. The body is mounted on an axle inside of container placed in canal produced in the base. Two identical springs are adjacent to their sliders and to container wall with corresponding neighboring end. Spring compression force is varied by means of connection unit joining external sliders and allowing them to be moved. Shaft rotation speed is measured and adjusted until length equality of both springs is established so that it reaches critical value of circumferential velocity of the body center of mass on corresponding rotation radius. Then the body set in rotation about the axle it is mounted on. Rotation frequency is adjusted and then the axle is detached from the drive. Body motion trajectory is recorded and time is recorded for each body rotation angle marker passing a basic mark. Time spent for rotating the body through an angle determined by adjacent pair of rotation angle markers and angular body revolution velocity are calculated for each of the mentioned rotation angles. Mean value of body revolution about its axis is determined. Difference in the mentioned angular body rotation velocities being observed, the angular body rotation motion velocity is considered not to be uniform. Then, the axle the body is mounted on is connected to the driving unit and frequency of its rotation about the axle is adjusted to reach the corresponding ratio value of angular velocity of body revolution about its own axis and its rotation in moving in loop-shaped orbit. The trajectory is recorded in moving in loop-shaped orbit with trajectory boundaries fixed within the limits of one body revolution. EFFECT: wide range of functional applications in researching processes taking place in the universe and astral system. 5 cl, 13 dwg _
