... The analysis shows, that asteroid rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...
