How I killed Pluto and Why It Had It Coming, Mike Brown

I have read five chapters so far, and I surprisingly didn't get bored reading them. 

I first chose this book because it was the one which triggered the most my attention: the colors used in the front cover, the question used as a title, and mostly because I decided I really wanted to know how this planet was not anymore one. But even though I was curious, I rather had low expectations about the book, and thought It was likely going to be a long scientific journal written by an astronomer who uses complex words to make me feel bad for not understanding anything. I have to say that that astronomers can also be really good story tellers, because I have quickly been immersed in the life of a man who follows his instinct and uses his knowledge, to successfully fulfill his most profound desires, and achieve the dreams he had when he was younger.

Mike Brown is an American astronomer and professor at the California Institute of Technology in Pasadena, who bet against the odds and the scientific community that there should indeed exist a tenth planet, beyond Pluto, one that has yet to be discovered. He had no evidence but knew that the telescopes used to find Pluto were far less precise than the one he was about to use in 1999. So he describes all the obstacles he had to go through, while informing the reader about interesting facts and raising questions related to astronomy, sometimes correcting false assumptions we have about the definition of a planet, or the size of our solar system. This long ride led him to two discoveries so far, one on them is Sedna, an object almost as big as Pluto, and the other is Diane, his wife.
