چکیده انگلیسی
Here we take as an example the very young Datura family, with a small 8-km parent body, and compare its size distribution to other families, with both large and small parent bodies, and created by both catastrophic and cratering formation events. We conclude that most likely explanation for the shallower size distribution compared to larger families is a more pronounced observational bias because of its small size. Its size distribution is perfectly normal when its parent body size is taken into account. We also discuss some other possibilities. In addition, we study another common feature: an offset or “bump” in the distribution occurring for a few of the larger elements. We hypothesize that it can be explained by a newly described regime of cratering, “spall cratering”, which controls the majority of impact craters on the surface of small asteroids like Datura.
