This episode we take a ride into the solar system and beyond. How are planets formed and how was our solar system formed? What are the long believed rules of planetary systems and why we now believe there is not one model that fits all. 

Dr Richard Parker is an astrophysicist in our School of Mathematical and Physical Sciences. During the episode he takes us around the solar system and further into the Milky Way galaxy - discussing migrating planets and even whether life can jump between planetary systems.
