At the main asteroid belt and Kuiper-belt region, it is commonly occurred that small bodies is disrupted into fragments by mutual collision and re-accumulated by its self-gravity. The tensile strength of these bodies is often neglected, however, they may gain the strength according to the growth of the mutual contact points (necks).Under low temperature, the growth process of the neck is mainly controlled by surface diffusion and evaporative condensation. In this study, we calculate the thermal condition in these bodies, and consider the growing process of the neck, which depends on the temperature. We try to find out effects of the distance from the sun and size of these objects.
