Intended Audience: 

Planetary formation functions much the way that 2-year olds eat; that is, most of it goes where it's supposed to, but a non-negligible fraction is dispersed in the vicinity, sometimes leaving at high speed.  In this colloquium I will cover (at a non-expert level) a series of topics related to the processes that occur in planetary systems as they form and evolve.  The size scales from dust to giant planets will be covered, including topics of: meteorite delivery; giant impacts that strip mantles off planets, exposing their bare cores; building the Oort cloud and models relating to "Planet 9"; and interstellar interlopers.
