Absolutely ƒucking fascinating. The first object we've encountered from beyond our own little neighborhood
--and it's unlike anything we've ever seen. What are the odds that other solar systems are filled with mostly familiar objects, but--coincidentally--the only object we've ever
observed just happens to be totally unique and unprecedented??

I'll Devil's Advocate my own question: we only noticed this thing because of the variance in brightness, thus the shape, thus we noticed the orbit and determined it's origin. We wouldn't have paid that much attention to a regular-shaped object. This is just
selection bias.
