Applications of the polarimetric techniques to study Solar system bodies are undergoing a phase of strong advancement. Recent observing campaigns have produced many important results, including an improvement of the capability to derive accurate estimates of the geometric albedo of asteroids, and the discovery of classes of objects displaying an unusual polarimetric behaviour. New developments suggest the existence of interesting links between polarimetry and spectroscopy. This session will be devoted the discussion of polarimetry as a diagnostic tool for the characterisation of small bodies of our solar system, and to the dissemination of the most recent results. A special attention will be paid to the potential contribution of polarimetry to the physical studies of potentially hazardous near-Earth objects.
