<p class="MsoNormal"><span style="font-size:10.5pt;font-family:Roboto;color:#262626">New theoretical and observational studies of planetary rings, meteoroids, and dust. These collections of small particles are sensitive to a wide variety of dynamical phenomena,
and so can provide information about the sources, sinks and transport of material. Rings can also encode detailed information about their dynamical environments such as their host planet's gravitational field, while meteoroids and dust interact with larger
bodies through surface impacts and atmospheric ablation and therefore contribute to surface weathering or airless bodies and metal deposition in planetary atmospheres. Subjects to be covered include: the structure, dynamics and composition of rings; characterization
of dust populations along with their effects on asteroids and spacecraft; dust chemistry; hypervelocity impacts of dust and meteoroids; the interaction of planetary rings with ionospheres, magnetospheres and interplanetary dust; and the origin and evolution
of the rings. In response to the Decadal Survey on Planetary Science and Astrobiology 2023-2032, this year we particularly welcome papers focusing on related future developments, including instrumentation, missions, and observations.</span><o:p></o:p></p>
