Kirkwood gaps occur at distances from the Sun where the asteroid would be in orbital resonance with Jupiter.In these instances,the asteroid passes Jupiter in exactly the same region of space each time it passes,and Jupiter tugs on it in the same direction every time.Over time this causes the asteroid to move out of the gap.
