Oh no! Another alien probe

[Anomalocaris]

No, but the length to width ratio of this object is not only the greatest we’ve ever seen, it is >3 Times greater than the next highest ratio we’ve seen.   So it seems reasonable to say it’s shape requires a formation circumstances we haven’t seen before.

So, out of the many, many interstellar objects we've seen since 4004 BC, this one is anomalous.

We believe interstellar objects of this size mostly if not entirely originated as circumstellar objects. The process that form young stars also create the only environment we know of that takes extremely diffuse interstellar dust, concentrate them, and keep them concentrated without absorbing them for long enough until there is time for sizeable objects to form. We’ve certainly seen very sizeable collection of circumstellar objects around our sun that formed this way. We would expect most of the interstellar objects to resemble the more numerous types of circumstellar objects found in our solar system. The surface characteristics of object is reassuringly similar to Kuiper Belt Objects in our solar system. But it’s shape is highly unusual.

There are 3 possibilities:

1. Our theories are correct but the shape of this object is truly freakish and simply represent an statistical extreme so far from the norm in both our solar system and interstellar space that we simply have not chance upon something like itbefore.

2. We are wrong and sizeable portions of interstellar objects formed in environments substantially different from comditions around the sun when the sun’s retinue of circumsolar Objects form.

3. Our theories are correct about how most interstellar objects form, but we have not considered conditions in interstellar space that can modify normal circumstellar objects into this unusual shape.
