Answer 1

If you want to dig into it more and really get the details, Mike Brown wrote a book about it. He discovered many of the Kuiper objects that “competed” with Pluto. The book is titled “How I Killed Pluto and Why It Had It Coming.” The “grandfathering” in of Pluto was actually discussed as part of the new definition of “planet.”
