"How I Killed Pluto and Why It Had It Coming" - awesome title for an Astronomy book

It’s not exactly an astronomy book. It’s more a memoir of an astronomer. But it’s funny and very well written.

Also, if you have the opportunity too see @plutokiller teach planetary science or give a lecture, I can recommend you do so!

> “One of the biggest flaws with the IAU definition is that you can have the same object in two different orbits,” says Kornfeld. “In one, it’s considered a planet, and in the other, it’s not considered a planet.”

So… planet Ganymede when? Or Titan?

It seems as though Pluto's primary problem is "clearing the neighbourhood." Given Pluto's orbit travels closer and further from the sun than Neptune, does Neptune also have the neighborhood clearing problem since it has not cleared Pluto?

  In celestial mechanics, "clearing the neighbourhood" (or dynamical dominance) 
  around a celestial body's orbit describes the body becoming gravitationally 
  dominant such that there are no other bodies of comparable size other than 
  its natural satellites or those otherwise under its gravitational influence.[0]

I'm in the same camp. I believe the classification of Pluto as a dwarf planet was arbitrary and inconsistent. I mean, it's been known as a planet for almost 80 years and suddenly we demote it?

I believe someone was trying to make a name for themselves here and ignoring the history of Pluto and its discovery.

Bring back Pluto!

As the article explains, if you bring back Pluto you must include Eris too, and perhaps Makemake and Haumea if you ignore is not as round as expected, and who know how many other undiscovered small object near them. (And Ceres? I like Ceres.)

Anyway, 9 is not an option, you must choose 8 or 10+.
