Two-dimensional slices showing possible asteroid morphologies after impacts on initially 160 m spherical bodies with varying boulder size-frequency distributions. The impacts on targets with a high packing of boulders produce impact craters, while impacts on targets with a loose packing of boulders produce a global deformation of the target. Due to the resolution employed in our simulations (see Sect. 2), the size and morphology of the impact craters was not determined.
