Russian solar-system cosmogonist Viktor Safronov was a protégé of  Otto Schmidt. In his 1968 Evolution of the Protoplanetary Cloud and the Formation of the Earth and Planets, Safronov quantified the theory for planetary formation from the accumulation of planetesimals, an idea generally attributed to  Thomas Chamberlin and  Forest Moulton around 1900. The Safronov theory includes the evolution of the planet’s mass, obliquity, and temperature as a function of the rate of accretion.
