Why are dwarf planets different? Why is there a gatekeeper at all? My suspicion is that the gatekeeping is a leftover from when there was a chance during all of the debating 5 years ago that dwarf planet would be declared a subclass of planet.Everyone feels the need to be able to answer the simple question: how many planets are there?
