This session is open to report about modelling and data of planetary, interplanetary and interstellar dust. This includes planetary rings, nano dust in the Solar System, cometary dust and interstellar dust observations. The data analysis of Stardust and Cassini results are welcome. Jovian dust models are necessary to prepare for the JUICE mission. Further missions are IKAROS and New Horizon. Laboratory investigations related to space weathering and hyper-velocity impacts support in-situ measurements. Lunar Dust and dusty plasma models or laboratory work are further topics of this session.
