Hugh, Hannah & Andrew turn their attention to a simple question with a very complicated answer: our favourite!

This month we are pondering how planets form. What do we know about planet formation from the Earth, observations from our Solar System, and of distant exoplanetary systems? Where are the gaps in our understanding of the processes involved? Do the theories and models of planet formation hold up to observational scrutiny? We might not be able to answer all (or any) of these questions definitively, and arguably we ended the discussion with more questions than when we started, but we had fun along the way!
