Movement of material point in Newton potential with singularity in origin of coordinates is considered. Differential equation describing dependence of square of orbital velosity on distance from origin of coordinates is obtained and its approximate solution is presented. In the case of large distance from origin of coordinates, square of orbital velosity go to non-zero value, which depends on space-time expansion increment.
