This is great and it has the prospect of possibly blossoming as well. As a comet, it may well never have been out gassed before. Thus it could become as bright and large as Haley did originally.
The other good news is that we are now beginning to discover these. As our observation density keeps rising, it is reasonable that we do capture images of a fair percentage of whatever the real traffic through ou solar system.
It is also plausible to position chase satellites as well able to accelerate to a matching velocity on the appropriate path that intersects even within our solar system. Thus intersection will become a valuable tool to sample incoming material.

Wait. *ANOTHER* interstellar object is passing through the solar system?
Sep 13, 2019
The object is called C/2019 Q4 (Borisov) — though that name may change, as I'll get to in a sec — and it was discovered in observations taken on August 30, 2019 at the Crimean Astrophysical Observatory by Gennady Borisov using a custom 0.65-meter telescope. It didn't take long to find the object had an, um, unusual orbit, and follow-up observations taken a few days later using a much larger telescope confirmed its strange nature. There have now been quite a few observations, and although many mysteries remain, we can be pretty sure this thing came from Out There.
To be probably too careful here, I want to say that there is a slim chance it's not from outside our solar system, but honestly at this point I wouldn’t put much money on that. As more observations come in it looks more and more like this is the real deal.
