Where Do Planets Come From?

With more than 4000 confirmed exoplanets, evidently, planet formation is common. There is also mounting evidence from observations, theory, and meteorites that planet formation starts very early (within 1 Myr after the formation of the host star). How do we then form and grow planets frequently and quickly enough to match the evidence?
I will present a very brief review of our current understanding of planet formation, before focusing on what I believe are the most likely ways to form and grow planets. I will then present previous and ongoing research on how newborn planets grow, potentially to the sizes that we see in our own Solar System. Finally, I will close with a laundry list of outstanding challenges and unanswered questions in the field.
Meeting will be conducted virtually. Directions will be sent to CAS Members.
