After almost three years of scientific operations, JWST has observed a large number of Solar System objects thanks to numerous GTO, DD-ERS, and GO programmes proposed in cycles 1 to 3. These observations, using all of Webb's instruments both in imaging and spectroscopic modes, have revolutionised our knowledge of a large number of Solar System objects, in particular cold and faint objects such as transneptunians, transitional objects and satellites of giant planets.

The aim of this workshop is to bring together the international community involved in the proposal, implementation and analysis of Webb's solar system programmes. During the workshop, the results of the investigations will be presented, along with their implications for the solar system in general. We will also address  how JWST can be used even more effectively to study the solar system, by providing training in data reduction and proposals writing. Laboratory astrophysics requirements will also be discussed, in order to make better use of the observations already obtained.
