> what's the largest tidal force it would have experienced? I have no idea of its past obviously, but near us this would be it, at closest approach to the sun the tidal force is greatest. > Differential solar pressure? Solar pressure is very low, it just applies that force for a very long time. It would act to compress it (flatten it), slightly. But I don't know what orientation it had when approaching the sun. It could have been tumbling and randomized any force. > Would it have encountered anything on its journey that should have dispersed it? Vaporization from heating is the only thing energetic enough that I can think of. But maybe other people can think of other things.
