If it's a depression and not just some photographic artifact making it seem so, then we might deduce it's a comet strike which would make sense since Ceres' vicinity to Jupiter along with it's goofy orbit causes it to be a target just asking to get clobbered. They speculate that Ceres is probably just a captured Oort Cloud object itself, drawn in by Jupiter long long ago.

If it is a comet strike, then it seems that Ceres is less like a planetoid and more like a giant hunk of comet-like material that's been rounded over time by gravity. Its surface would be more like very compressed frozen vacuum cleaner lint than anything like the giant ball of iron the Earth is made of.

Jupiter, that lunatic planet, simultaneously tries to murder us and rescue us in relation to these Oort Cloud objects striking the Earth. Knowing what we know now, we might have chosen a better name for a fickle classical Roman/Greek diety to represent the largest planet in our Solar System.
