Recently discovered was the origin of the famous fable Pinocchio.
It comes from the torment that the "planet" Pluto has suffered since the early Greek times.
Pluto did not evolve with the rest of the solar system of which Earth is a feature part, it was captured and began orbiting the sun Sol after observing the rest of the planets doing this, and feeling an overwhealming attraction to do so as well.
However, Pluto has not been givin an easy time about all this orbiting business, with most of the other planets and their inhabitants stating that Pluto isn't really a real planet, and shouldn't be so called one nor included in the classifications the other planets bask in.
All Pluto wants is to be a "real planet".
Also, Pluto and Pinnochio both start with P and end with O. This is not a coincidence.
