Pluto lost its planethood status because of its size; there is a passel of TNOs with Pluto being the first. All of that stuff was expected to be geologically dead, but Pluto and its moons baffle deep time proponents with activity . There are volcanoes out yonder such as Jupiter's moon Io , and some that expel ice instead of lava. Pluto has some of these.
