  In a previous paper by the author was proposed a new metric for the
gravitational field of a thin rotating disk physically different from the Kerr
metric. The metric is admissible for any angular momentum of the disk. As
demonstrated in the present paper the parameter determining the angular
momentum of the Milky Way greatly exceeds its gravitational radius so that the
Kerr metric physically admissible only if the angular momentum is sufficiently
small is completely inapplicable to the Milky Way. It is shown on the basis of
the new metric that the rotation of the Milky Way plays a decisive role in the
motion of satellites in its gravitational field. The effects due to the
rotation can imitate the presence of hypothetical dark matter.
