Accurate measurements of Solar-System objects can reveal information on our origin. In addition, the characterisation of exoplanets and exoplanetary systems provides a broader view of planets and planetary systems. These can be used to better understand planet formation and evolution. Despite the great progress in theory and observations the following key questions remain unsolved:

- How do planets form?
- What determines the architecture of planetary systems?
- How do planetary systems evolve?
- Is our Solar System unique?

In this session we invite abstracts related to the formation and evolution of planets and planetary systems. This includes the Solar-System as well as exoplanetary systems, and both theoretical and observational studies.
