[1] The circular peak ring of the Chicxulub impact crater is not concentric with the outer rim of the structure, as defined by both gravity and seismic data. Although this has been attributed to an oblique impact, and used to define the direction of impactor approach, different groups have suggested radically different approach azimuths based on the same data sets. We investigate the putative correlation between peak ring offset and impactor azimuth by examining a suite of 19 peak ring craters on Venus, for which the impactor's approach direction is known from their asymmetric external ejecta. We find no statistically significant correlation between peak ring offset and the azimuth of the impactor's approach.
