Maybe there is a middle way. I can imagine that an impact into a very porous object might produce a crater, with characterisic features such as a central peak, that would nevertheless be more than usually sunken in. This might happen if the impact shattered an open structure and collapsed all the voids within. Don't ask me to 'produce' such a porous object. I don't know how to do it. But Hyperion is so peculiar that I'm prepared to entertain strange ideas.
Another thought about central peaks. I've always assumed they were produced by outward blasted material 'sloshing' inward after an impact, but I'm not sure this works in low g environments like Hyperion (and Vesta S). |
