Unconfirmed exomoon could be unlike any of those in our solar system

René Heller, a space scientist with the Maxx Planck Institute for Solar System Research has uploaded a paper to the arXiv preprint server offering possible attributes for the still-unconfirmed exomoon Kepler 1625 b-i. He suggests that if the exomoon does truly exist, it is probably unlike any of the moons in our solar system, which suggests that theories about the origins of moons might have to be expanded.
