Аннотация:The paper discusses the approximation of the potential of small celestial bodies with irregular mass distribution among four mass points. Examples of Geographos asteroid (1620) and Churyumov-Gerasimenko comet (67P) are used to illustrate the calculation of such potential approximations limitations values on the surface of those celestial bodies. Distribution of the values is depicted on six projections of the bodies onto three mutually perpendicular planes. Also points of surfaces in which approximated values of potential reach absolute minimum and maximum are shown.
