It’s a comet.
It's a very large rock. It's from somewhere very far away in the very distant past and there will be lots of things about it that we have never seen before.
Now that we have become good at spotting these things, we will see quite a few more of them. There will be many surprises in how they behave and what they are composed of. Entire theories of planetary formation and stellar evolution will be upended and drastically revised. Eventually we will be setup to launch a probe that will catch one for a closeup look.
From professors and scientists will come a great wailing, the gnashing of teeth, and rending of garments. New reputations will be made and old ones discarded.
Good times.
