	Gravitation is one of
the central forces playing an important role
in formation of natural systems like
galaxies and planets. Gravitational forces between particles of a
gaseous cloud transform the cloud into spherical shells and disks of higher
density during gravitational contraction. The density can reach that of a solid
body. The theoretical model was tested to model the formation of a spiral
galaxy and Saturn. The formations of a spiral galaxy and Saturn and its disk
are simulated using a novel N-body self-gravitational model. It is
demonstrated that the formation of the spirals of the galaxy and disk of the
planet is the result of gravitational contraction of a slowly rotated
particle cloud that has a shape of slightly deformed sphere for Saturn and
ellipsoid for the spiral galaxy. For Saturn, the sphere was flattened by a
coefficient of 0.8 along the axis of rotation. During the gravitational contraction, the major part of the cloud transformed into a planet and a minor part transformed into a disk. The
thin structured disk is a result of the electromagnetic
interaction in which the magnetic forces acting on charged particles of
the cloud originate from the core of the planet.
