For those who still think Pluto is a full planet, I suggest reading “How I Killed Pluto and Why It had it Coming” by Mike Brown,

Dr. Alan Stern wrote a response to that in an article: "“Why Pluto is a Planet, The Embarrassment of the IAU, and Why They Had It Coming”

It's mentioned in a Forbes article about Stern.

The IAU were a bunch of clowns over this issue. The reasons they gave for downgrading Pluto were laughable.

But, the results were still right. Pluto isn’t a planet. And Mercury may not be one either.
