Calculation of the gravitational force between non-point masses as an integral of differential small mass elements. Using the center of mass as the value of the distance in the Newtonian equation is not generally applicable. Right in case of large ratios of distance to the size of the masses. In case of small ratios, a gravitational point is created outside of the center of mass. The deviation of the gravitational point from the center of mass is calculated as an approximation for masses with homogeneous density. That is a theoretical approach. The special case of touching of the masses was not processed. It leads to singularities. Masses with inhomogeneous density require further calculations.
