This is a much better explanation for the anomalies of Oumuamua. turns out trhat a cloud of duct can do the job and it also tells us that the solar acceleration would separate this cloud from any more massive objects as well.
These would be small and dark and soon separated.
Nice spur to the imagination though and there must be lots of this out there..
Oumuamua Was a Small Comet, It Broke Apart and then Became a Cloud of Debris
In the absence of any sign of outgassing, the size of the solar acceleration implies a very high surface-area-to-mass ratio. This means it was a monstrous, extremely fluffy aggregate of loosely-bound dust grains.
