My hypothesis is it is leading debris from a planet that was near a supernova. If my hypothesis is correct, then depending on how far away the supernova was the expected radial distribution pattern would tell us if we could expect to see more.
Next steps would be to:
1) Determine which supernova in the past were closest to earth.
2) Calculate an origin of the item based on speed/trajectory prior to entering our system and look for past super-nova in that direction.
I’m sure there is some astrophysicist doing just that currently.

He was, but unfortunately, life caught up to him and he beat himself to death ... :)
