The ensemble of now well over 300 discovered planetary systems displays a wide range of masses, orbits and-in multiple systems-dynamical interactions. These represent the endpoint of a complex sequence of events, wherein an entire protostellar disk converts itself into a small number of planetary bodies. Here we present self-consistent numerical simulations of this process, which produce results in agreement with some of the key trends observed in the properties of the exoplanets. Though the typical formation history of a planetary system is highly stochastic, there are nevertheless clear correlations between a system's birth disk and the characteristics of the mature planetary system which ultimately grows from it. Analogues to our own Solar System appear to be a less common outcome, originating from disks near the boundary between barren and (giant) planet-forming.
