>>12874939It is a planet, just a "minor planet" that's grouped with other simila bodies (Eris, Sedna, etc.) based on its elliptical orbit, small size (yes, smaller than our moon) and other factors. Just because it's not a major planet doesn't mean it isn't heckin valid - it's just a smarter categorisation because otherwise we'd have heaps of other planets to include (like Eris, which is even more massive than Pluto)
