Sorry I have been away for a while!Is that THE real ALAN STERN?I have a question:Since Charon,nix and Hydra seem to have originated from impacts with Pluto,would it be reasonable to assume that we should be seeing big impact craters on Pluto,unless of course there is some process that is refreshing the surface to obliterate such major events??What are the predictions if any have been made??

THe giant collision that produced Charon, Nix, and Hydra did not leave an impact scar because it remelted Pluto. For KBO collisions and cratering predicts on Pluto and Charon, see Durda & Stern (2000) in Icarus; I belirve these remain the latest model calculations. -Alan |
