Complex rotations of the asteroid 45 Eugenia

The class of inertial rotation of the celestial object (45) Eugenia is considered. Using a new original method for calculating angular dynamics in absolute axes, it is shown that tumbling motion of Eugenia occur at any tilt of the large diameter to the axis of the initial rotation. All possible spin states of the asteroid are determined. The conditions under which the most active rotations of the object under consideration occur are found.
