ABSTRACT
Different aspects affecting the dynamics of nonspherical dust grain in plasma are discussed. The equations of motion of relatively slowly spinning nonspherical grain immersed in a subsonic plasma flow are derived. Based on these equations it is shown that the dynamics of rotationally symmetric grain is equivalent to the motion of symmetric top in the gravity field. The precession of the grain axis can result in significant oscillations of grain trajectory in the direction normal to plasma velocity.
