Pluto is interesting: a former planet, now classified as a dwarf-planet or celestial snowball. But, does it really matter what we call Pluto? The name itself has no effect on the nature of Pluto itself; it will continue to be what it is.
Pluto is different. But it doesn’t have to be aware of what the other planets are doing, nor does it study what makes the others so similar. It is uniquely its own mass, and contained within its own orbit.
It’s unique by being simply itself. As are you.
