The largest impact craters on the Moon are multiring basins, which exhibit three or more concentric topographic rings. Multiring basins dominate the crustal structure, tectonics, and stratigraphy of the Moon. Understanding how these basins form is crucial for understanding the evolution of ancient planetary crusts. I will present hydrocode simulations that demonstrate the processes involved in the formation of these impact basins and their rings. Our results show that both ring locations within the basin and spacing between rings are sensitive to target thermo-mechanical structure. I will also discuss how simulations of multiring basin formation on Venus and icy moons can be used to constrain the interior structure of a diverse range of planetary bodies.
