In the last 15 years, people’s understanding of how the Solar System evolved into what we observe today has greatly expanded. This became possible as advances in scientific computing enabled us to fully explore a wealth of observational data and -- more importantly -- the powerful theory of Celestial Mechanics, going far beyond its traditional boundaries. As a result, a new theory of Cosmogony has emerged, contradicting the traditional view of a 'perfect clock'-like system; this theory is also applicable to other worlds (i.e. extra-solar systems). In this talk, the speaker begins with a short presentation of the populations of celestial bodies in the Solar System. Then, he explains the basic scientific ideas on which traditional cosmogonic models were based, and discuss how these models fail and why. Finally, the speaker discusses recent theoretical models that explain how the Solar System came to be.
