metadata.value: The problem of approximation of the gravitational potential of a rigid body by the potential
  of a system of four identical point masses is studied. Considering the potential in the form
  of expansion by a parameter characterizing the ratio of the mean body size to the distance
  to the test point of space, an approach is proposed to construct an approximate expression
  up to the terms of the third order of smallness. This approach is used to construct a model
  of the field of attraction for the comet nucleus (67P)Churyumov—Gerasimenko.
