The planet Pluto is not a habitable planet, but rather a minuscule icy ball of rock, in short Pluto has suffered the same fate as mercury. In this timeline, Jupiter's increased gravitational pull pulled nearly all the objects in the Kipper belt and Oort cloud closer, thereby greatly increasing Pluto's mass, but still left it frozen. Pluto is the farthest planet from Umimon, though it becomes the closest planet to our Sun for half of its orbital period. The USR use's it as a jumping-off point for their military campaigns in the inner solar system, building many sphere like structures, that serve as training and production facilities. Pluto has one moon Charon, which has been colonized and excessively mined.
