Pol is the most distant moon of Jool also it is the most odd one….
But what does this tiny pollen grain hides? It is obvious that it is a something that entered the sphere of influence of Jool. But what and where was it before the capture? It could be just a simple comet but it’s size says something different. Perhaps it was something from outside the Kerbol system… It could be a captured planemo that was pulled by Kerbol. Evidence of that is unique non-comet color and weird landscape which is different from comet surface…
Perhaps maybe it was a planetoid, or better say not formed planet…. One thing for sure It is not from Jool it’s different and strange .It would be great if you will help to improve this theorie by your suggestions!
