Abstract A summary of experimental and theoretical studies of atmosphere-related phenomena accompanying high velocity impact processes is presented, including asteroid and comet passage through the atmosphere, their impact on the surfaces of different planetary bodies, blast waves in the atmosphere and their influence on surface life. These phenomena are illustrated with the Tunguska 1908 event. The newly appreciated effects of the atmosphere on crater formation are illustrated by the impact craters on the surface of Venus that were identified on the Venera 15 and 16 radar images. The dense Venusian atmosphere influences the crater morphology and size distribution. The comparison of observed data and theoretical models permits us to estimate the strength properties of celestial bodies such as asteroids and comets.
