I agree it's very unlikely that it's something of artificial origin, but if it's just a rock it's far from uninteresting. It would be the first material recovered from outside our own solar system. It could be surprising in all kinds of ways.

Positive confirmation that physics and chemistry works similar elsewhere to how it does in our solar system is a big deal. We suspect it does, but having material in hand from somewhere else is a huge additional data point.

  That’s something I hadn’t considered. Quite valuable understanding!

    Yes, it would be very interesting if there was a material in it that hasn't been discovered yet. I imagine there are conditions out there, way out there, that bring forth conditions that aren't available here that could create new things not seen here.

      This is a fascinating area. Of we do have "materials" here that came from outside of our solar system because we all contain atoms with higher atomic numbers than helium, like carbon, oxygen etc, that have been through multiple solar "cycles" that gradually make higher atomic number atoms as stars go through the ages. So you and I are both made of matter that came that way, from outside the solar system. Of course it's different if we have rocks or some such that we could tell came directly out of the solar system, and not assembled directly here.

        Well no gold was formed on earth. It all comes from stars. I'm more meaning things that would be uncommon in the universe, like perhaps being very close to a pulsar for millions of years.

  Why would physics be different in a neighboring system? Are there theories here? And if it enters our system, wouldn’t it be bound to our physics? How could you even know it was different before?

It seems to me that we know so little about the universe that we can’t say if it’s likely or unlikely.

  We don't know much, but I do think we know enough to say it's unlikely. We've never seen any evidence for intelligent life outside of Earth. Using Bayesian logic, that gives pretty good odds in favor of it being of natural origin.
