In this paper, we will deal with one of the most fascinating problems of the Solar System: the origin of the double face of Iapetus, where one half of the satellite is significantly brighter than the other. The "transfer of mass" process (see Marchi et al. 2001) may be a viable explanation for the visible dichotomy. In this process a satellite undergoes mass transfer from other satellites belonging to the same system. We analyze the pair Hyperion-Iapetus and suggest a possible explanation for the formation of the dark region, which is also known as Cassini Regio.

Abstract
In this paper, we will deal with one of the most fascinating problems of the Solar System: the origin of the double face of Iapetus, where one half of the satellite is significantly brighter than the other. The "transfer of mass" process (see Marchi et al. 2001) may be a viable explanation for the visible dichotomy. In this process a satellite undergoes mass transfer from other satellites belonging to the same system. We analyze the pair Hyperion-Iapetus and suggest a possible explanation for the formation of the dark region, which is also known as Cassini Regio.
