3D Simulations of Comet Impacts into the Atmospheres of Titan and Venus

We present results of three-dimensional numerical hydrodynamical calculations of the impacts of comets into the atmosphere of Titan. Our goal is to develop formulae that may be used to predict the sizes and distributions of craters that are expected to exist on Titan's surface and be found by the Huygens probe of the Cassini mission that will arrive at the Saturn system in 2004. We also compare our results with similar calculations done by us for asteroid impacts into the atmosphere of Venus
