Around the Earth-moon system orbit, and far away, would be less infeasible. Something that big can&#x27;t be stable on Moon orbit…<p>Firstly the Moon has mascons¹ which makes it a pain to orbit around even for small satellites.<p>Secondly, I don&#x27;t what the Roche limit² of Pluto around the Moon would be, but I wouldn&#x27;t be surprised if it overlapped with the Roche limit of Pluto around the Earth. That means that in order to not disintegrate and become a ring system of the Moon or outright crash on the surface, the body would have to be so far away from the Moon that it would disintegrate and crash or form a ring system around Earth.
