The results of catastrophic disruption experiments on static and rotating targets are reported. The experiments used cement spheres of diameter 10cm as the targets. Impacts were by mm sized stainless steel spheres at speeds of between 1 and 7.75km s−1. Energy densities (Q) in the targets ranged from 7 to 2613Jkg−1. The experiments covered both the cratering and catastrophic disruption regimes. For...
A model of impact disruption of the bodies with sizes from the laboratory scale to that of an order of 100km is developed. On the lowermost end of the target size the model is based on the numerous laboratory data related to the mass–velocity distribution of the impact produced fragments. On the minor-planets scale the model is supported by the data related to the largest observed craters on small...
We consider the largest impact craters observed on small satellites and asteroids and the impact disruption of such bodies. Observational data are considered from 21 impact-like structures on 13 satellites and 8 asteroids (target body radii in the range 0.7–265 km). If the radius of the target body is R and the diameter of the largest crater observed on this body D, the ratio D/R is then the main...
