Was 'Oumuamua a cosmic dust bunny?

But the forces would be slight, and perhaps electrostatic or whatever bonds were there would be strong enough.

The path seems to not take it near anything with too step a gravity well, so the gravitational forces wouldn't be that bad on it, either.

That leads to the next question: If there's one, there must be more. It's unlikely we'd see many unless we were looking. At the same time, if they got too close to a minor object they'd be shredded, and all that would be left would be dust.

I wonder if Stardust samples would shine any light on this? (Yeah, everybody's forgotten about Stardust. It didnt' find cosmic tardigrades, so nobody cared.)
