Scientists have theorized for decades that Pluto's unusually large moon Charon formed through a process similar to Earth's moon – a massive collision between two planet-sized bodies, that left Pluto and Charon behind. The process by which this giant impact occurred, and how Charon became subsequently captured as Pluto's satellite, remained poorly understood until recently. In this talk, we'll learn about some of the cutting-edge simulations that revealed new insight into Pluto and Charon's initial collisions, as well as how that impact may have big implications for the system's geological evolution, including how we get to the surfaces that were imaged by New Horizons in 2015.
