Our Solar System's Violent Past   

In recent years, it has become increasingly clear that during the early stages of our solar system's history a number of major chaotic impact events occurred. This recognition, along with our increased knowledge of exoplanets in other stellar systems, has led to the idea that the major planets of our solar system may have migrated over considerable distances in the past, causing this chaos. In this class, we will discuss some current ideas on how this planetary migration may have happened.
