Аннотация:Approximation of the gravitational field of an irregular celestial body by the gravitational attraction field of four massive points is studied here in the framework of K-means method, known from the theory of pattern recognition. Using this approach, the simplified models for gravitational fields of asteroid (1620) Geographos and comet (67P) Churyumov-Gerasimenko are constructed. For asteroid (1620) Geographos, the proposed model is compared with the previously used one when this asteroid is represented by four cotangent spheres with co-planar centers.
