Pluto, you are still a planet in my heart.

When you think about the obsession in speculative and weird fiction from the
beginning of twentieth century with the idea of a hidden planet, a malevolent
influence hosting everything evil and nefarious in the galaxy waiting in the
dark to strike on an unsuspecting galaxy, that's Pluto. It's not his fault: it all
started when Le Verrier predicted the existence of an undiscovered planet
based on the available data.

The idea of a dark planet that none can see but that can disturb the actions of
other solar objects was so evocative that it quickly appeared in literature and
art, for instance as the planet Yuggoth in the Cthulhu cycle from H.P.
Lovecraft.

At some point Pluto was called "Planet X": is there anything more vintage
science fiction that a planet named Planet X? You can almost ear a theremin
playing in the background.

And then there's the whole thing about Pluto not being a proper planet. In the
end I'm still unsure if Pluto is a planet or not, but I guess we may say that
planetary status is a spectrum?
