My daughter Lilah, now five years old, is mad at me for killing Pluto. When I began a project 13 years ago to chart the slowly-moving objects of the distant outer solar system, my goal was never to pull Pluto off of its cherished planetary pedestal. I wanted to be a planet discoverer, like William Herschel or Clyde Tombaugh before me. I had a strong feeling that somewhere out there something bigger than Pluto was lurking, and I knew that whoever found it would get to claim the mantle as the only living planet discoverer.
I was right. Something bigger than Pluto was out there (or at least something more massive than Pluto; sizes are a little harder to pin down precisely) and one January morning in 2005, my small team of astronomers and I found it. We announced the discovery of the 10th planet to an unsuspecting world late on the afternoon of Lilah’s 22nd day of life. A little after her first birthday, though, the doors to the planetary club were locked and Pluto and my own discovery were kicked out on the curb. The solar system was down to only eight planets.
It was hard not to mourn the loss of my now ex-planet, except for the fact that I had to admit that kicking it out was the most scientifically sensible thing to happen to planetary classification since asteroids were also kicked out almost 200 years ago. The solar system is a beautiful and profound place, and it is made richer with the realization that the eight planets are the foundation throughout which countless smaller bodies continuously swirl.
When Pluto was first demoted, people said to me, “What about the children? How could you do this to them?” But, in fact, children live lives that are always changing. It’s the adults who have had the hardest time reconciling the new understanding of the solar system with what they remember from when they themselves were children. So, it made sense that I used to joke about what would happen the moment when Lilah first learned about the solar system. She would come home, and I would say, “Tell me all about the eight planets,” and when I would try to tell her about the olden times when we used to think there were nine—or even ten!—planets, she would slowly shake her head and exclaim, “Daddy, adults are so stupid.”
But I was wrong.
Lilah knows all about Pluto. She has a stuffed dog, a planet lunch box, a solar system place mat at the dinner table. She feels as warmly towards the ice ball as someone ten times her age, and, like many of those older people, she is mad at the person who killed it. Lilah, though, has a solution. She recently told me, “Daddy, I know that you had to kill Pluto, but will you promise me one thing?”
“Of course,” I said.
“You have to go find another planet, and when you do, you have to name it Pluto for me, OK?”
So my search of the skies continues.

Review
"Brown’s brisk, enjoyable How I Killed Pluto and Why It Had It Coming chronicles the whole saga [of the demotion of Pluto] and, in the process, makes Pluto’s sad fate easier to take. If we’ve lost a planet, we’ve gained a sprightly new voice for popular science…Writing with an appealing wit, Mr. Brown resists the glibness to which science popularizations sometimes fall prey. Instead he leavens his scientific account with a memoir of how he discovered the joys of becoming a husband and a father during the same period that he thought he was discovering planets. It’s a refreshing twist on stereotype: the scientist neither as madman nor mystic, but mensch…The cheerful, unaffected tone makes it hard not to like Mr. Brown, and to root for him when he finds himself in the midst of controversy… Amazingly, the author spins these parliamentary proceedings into a nail-biting roller-coaster ride: the skullduggery of secret committees, the raucous debate, the white-knuckle final tally. How many planets will we end up with? Eight? Twelve? Hundreds? Will the astronomers accept a definition that satisfies cultural expectations—but is bad science? Or will they find the courage the kill Pluto?... Brown narrates this entire story with so little rancor and so much generosity to rival astronomers that he can seem too good to be true. He even keeps his cool, and his class, while his research is plundered and his reputation attacked. It turns out you can kill a planet and still be a pretty nice guy.”—The Wall Street Journal
“Brown's brilliant scientific memoir brings clarity and elegance to the complexities of planetary science. Brown is also a surprisingly self-effacing and entertaining genius. But what comes through clearest is his uncompromising integrity, his 'take-no-prisoners' belief in science. He puts principle above his own best interest... [An] out-of-this-world science memoir.”—Minneapolis Star Tribune
"Brims with humor and charm...exhilarating."—LA Times
“Brown clearly explains difficult scientific topics with humor and warmth…Deftly pulling readers along on his journey of discovery and destruction, Brown sets the record straight and strongly defends his science with a conversational, rational, and calm voice that may change the public’s opinion of scientists as poor communicators.”—Publisher’s Weekly (starred review)
“Finally I have someone to whom I can forward the hate mail I get from schoolchildren. After all these years, the real destroyer of Pluto has confessed. Part memoir and part planetary saga, How I Killed Pluto invites you into planetary scientist Mike Brown’s office, his home, and his head as he tells the story of how his research on the outer solar system led directly to the death of Pluto, the planet.”—Neil deGrasse Tyson, Frederick P. Rose Director of the Hayden Planetarium and author of The Pluto Files: The Rise and Fall of America’s Favorite Planet
“Damn Mike Brown for exploding the solar-system model we’ve been carrying around in our heads since elementary school. Praise him for showing us that stargazing, far from being a dead science, is a living, changing wonder.”—Benjamin Wallace, author of The Billionaire’s Vinegar
“Romance, intrigue, laughter, skullduggery, and most of all: science! Mike Brown has done more than anyone to reshape our view of the solar system, and this first-person account of his discoveries is an irresistible page-turner. You’ll have so much fun, you won’t even notice how much you’re learning.”—Sean Carroll, author of From Eternity to Here: The Quest for the Ultimate Theory of Time
“Science is at its best when it shakes up our thinking, and when it comes to planets, Mike Brown has grabbed on with both hands. Whether you think Pluto is a planet or just another ice ball, you’ll find Brown’s tale of exploring the outer solar system a charming and even endearing read. If Pluto is indeed dead, then its sacrifice was not in vain.”—Philip Plait, author of Death from the Skies!

What Is a Planet?
One December night in 1999, a friend and I were sitting on a mountaintop east of San Diego inside a thirteen-story-tall dome. Only a few lights illuminated the uncluttered floor of the cavernous interior, but above you could vaguely see the bottom half of the massive Hale Telescope at Palomar Observatory. The Hale Telescope was, for almost fifty years, the largest telescope in the world, but from where we sat, with the weak yellow incandescent lighting being swallowed in the darkness above, you would never have guessed where you were. You might have thought you were deep in the interior of a pristine Hoover Dam, with cables and wire and pipes for directing the flow of water around. You might have believed that the steel structures around you were part of the far underground support and control of a spotlessly clean century-old subway system. Only when the entire building gently rumbled and a tiny sliver of the starry sky appeared far over your head and the telescope began to move soundlessly and swiftly to point to some new distant object in the universe, only then would you be able to make out the shadowy outline of the truss all the way to the top of the dome and realize that you were but a dot at the base of a giant machine whose only purpose was to gather the light from a single spot beyond the sky and focus it to a tiny point just over your head.
Usually when I am working at the telescope I sit in the warm, well-lit control room, looking at computer screens showing instrument readouts, staring at digital pictures just pulled from the sky, and pondering meteorological readings and forecasts for southern California. Sometimes, though, I like to step out into the cold, dark dome and stand at the very base of the telescope and look up at the sky through the tiny open sliver high overhead and see—with my own eyes—exactly what the giant machine is looking at. This December night, however, as I was sitting with my friend inside the dark dome, there was no sky to see. The dome was fastened closed, and the telescope was idle because the entire mountain was covered in cold, dripping fog.
I tend to get quite glum on nights when I’m at a telescope with the dome closed and the precious night is slipping past. An astronomer gets to use one of these biggest telescopes only a handful of nights per year. If the night is cloudy or rainy or snowy, too bad. Your night on the telescope is simply lost, and you get to try again next year. It’s hard not to think about lost time and lost discoveries as the second hand very slowly crawls through the night and your dome stays closed. Sabine—my friend—tried to cheer me up by asking about life and work, but it didn’t help. I instead told her about how my father had died that spring, and how I felt unable to really focus on my work. She finally asked me if there was anything that I was excited about these days. I paused for a few minutes. I momentarily forgot about the freezing fog and the closed dome and the ticking clock. “I think there’s another planet past Pluto,” I told her.
Another planet? Such a suggestion would have generally been scoffed at by most astronomers in the last days of the twentieth century. While it is true that for much of the last century astronomers had diligently searched for a mythical “Planet X” beyond Pluto, by about 1990 they had more or less convinced themselves that all that searching in the past had been in vain; Planet X simply did not exist. Astronomers were certain that they had a pretty good inventory of what the solar system contained, of all of the planets and their moons, and of most of the comets and asteroids that circled the sun. There were certainly small asteroids still to be discovered, and occasionally a bright comet that had never been seen before would come screaming in from the far depths of space, but certainly nothing major was left out there to find. Serious discussions by serious astronomers of another planet beyond Pluto were as likely as serious discussions by serious geologists on the location of the lost continent of Atlantis. What kind of an astronomer would sit underneath one of the biggest telescopes in the world and declare, “I think there’s another planet past Pluto”?
...
Almost a decade earlier, in the late summer of 1992, I was in the long middle years of my graduate studies at Berkeley (the place where I was taught that Planet X certainly did not exist and that we already knew pretty much everything we needed to know about what there was in the solar system). I didn’t think much about Planet X those days. I was midway through a Ph.D. dissertation about the planet Jupiter and its volcanic moon Io. When you’re midway through a Ph.D. dissertation, your mind acquires narrow blinders, so I didn’t think much about anything other than Io and how its volcanoes spewed material into space and affected Jupiter’s powerful magnetic field. I had so few thoughts to spare for most of the quotidian universe that I had fallen into a pattern of every day eating the same lunch at the same coffee shop right next to the Berkeley campus and having dinner at the same burrito stand a block away. At night I would ride my bicycle back down toward the San Francisco Bay to the marina where I lived on a tiny sailboat. The next morning I would start all over again. Less time thinking about what and where to eat and sleep meant more time thinking about Io and volcanoes and Jupiter and how they all fit together.
But, occasionally, even obsessive Ph.D. students need a break.
One afternoon, as on many times previous, after spending too much time staring at data on my computer screen and reading technical papers in dense journals and writing down thoughts and ideas in my black bound notebooks, I opened the door of my little graduate student office on the roof of the astronomy building, stepped into the enclosed rooftop courtyard, and climbed the metal stairs that went to the very top of the roof to an open balcony. As I stared at the San Francisco Bay laid out in front of me, trying to pull my head back down to the earth by watching the boats blowing across the water, Jane Luu, a friend and researcher in the astronomy department who had an office across the rooftop courtyard, clunked up the metal stairs and looked out across the water in the same direction I was staring. Softly and conspiratorially she said, “Nobody knows it yet, but we just found the Kuiper belt.”
I could tell that she knew she was onto something big, could sense her excitement, and I was flattered that here she was telling me this astounding information that no one else knew.
“Wow,” I said. “What’s the Kuiper belt?”
It’s funny today to think that I had no idea what she was talking about. Today if you sat next to me on an airplane and asked about the Kuiper belt, I might talk for hours about the region of space beyond Neptune where vast numbers of small icy objects circle the sun in cold storage and about how, occasionally, one of them comes plummeting into the inner part of the solar system to light up the skies like a comet. I might talk about the very edge of the solar system, where millions of little icy bodies never quite got gathered up into one big planet but instead stayed strewn in the disk surrounding the solar system. And I might tell you a little history, about how in the early 1990s no one had seen such a thing as this Kuiper belt, but a small group of astronomers who had predicted its existence had named the region the Kuiper belt after Dutch American astronomer Gerard Kuiper, who had speculated about its existence decades earlier. And finally, if you were still listening and the plane had not yet landed, I would tell you how this Kuiper belt was finally seen, for the first time, in the late summer of 1992, and how I first learned about it on the roof of the Berkeley astronomy building a day before it appeared on the front page of The New York Times.
But when Jane told me she had just found the Kuiper belt, I didn’t know any of this. Jane explained. She had not found this vast collection of bodies beyond Neptune, exactly, but simply a single small icy body circling the sun well beyond the orbit of Pluto. The body was tiny—much, much smaller than Pluto—and as far as anyone knew for sure, it might have circled the sun all alone at the edge of the solar system. But still, exciting, right?
Cute, I thought. But it’s just one tiny object, and it’s farther away than Pluto. How could that matter?
So I nodded and listened and, like any diligent Ph.D. student midway through a dissertation, eventually walked back down the stairs, stepped into my office, and reentered the world of Jupiter and Io and volcanoes, where I actually resided.
I was wrong, of course. Even though the object discovered was only a lonely, relatively tiny ball of ice orbiting beyond Pluto, it showed that astronomers had been wrong: They didn’t actually know everything; there were things still to be found at the edge of our own solar system. Some astronomers were reluctant to consider this new possibility seriously, and they dismissed the discovery as nothing more than a fluke that presaged absolutely nothing. But soon, as more and more astronomers became excited about the possibility of discovery and started searching the regions beyond Pluto, more and more of these small bodies began to be found.
By the end of 1999, on the foggy December night when Sabine and I were sitting underneath the Hale Telescope at Palomar Observatory and I was proclaiming that I thought there were new planets to be found, astronomers around the world had already discovered almost five hundred of these bodies in a vast disk beyond the orbit of Neptune in what looked very much indeed like the Kuiper belt. From being something that most astronomers had perhaps heard of once or twice, the Kuiper belt had become the hottest new f...

About the author
Mike Brown is the Richard and Barbara Rosenberg Professor of Planetary Astronomy at the California Institute of Technology and has been on the faculty there since 1996. He specializes in the discovery and study of bodies at the edge of the solar system. Among his numerous scientific accomplishments, he is best known for his discovery of Eris, the largest object found in the solar system in 150 years, and the object which led to the debate and eventual demotion of Pluto from a real planet to a dwarf planet. Feature articles about Brown and his work have appeared in the New Yorker, the New York Times, and Discover, and his discoveries have been covered on front pages of countless newspapers worldwide. In 2006 he was named one of Time magazine's 100 Most Influential People as well as one of Los Angeles magazine's Most Powerful Angelinos. He has authored over 100 scientific paper. He is a frequent invited lecturer at astronomical meetings as well as at science museums, planetariums, and college campuses. At Caltech he teaches undergraduate and graduate students, in classes ranging from introductory geology to the formation and evolution of the solar system. He was especially pleased by his most recent honor, the Richard P. Feynman Award for Outstanding Teaching at Caltech.
Brown received his AB from Princeton in 1987, and then his MA and PhD from University of California, Berkeley, in 1990 and 1994, respectively. He has won several awards and honors for his scholarship, including the Urey Prize for best young planetary scientist from the American Astronomical Society's Division of Planetary Sciences; a Presidential Early Career Award; a Sloan Fellowship; and, of course, the one that started his career, an honorable mention in his fifth-grade science fair. He was also named one of Wired Online's Top Ten Sexiest Geeks in 2006, the mention of which never ceases to make his wife laugh.

- Reviewed in the United States on December 12, 2010The bit about killing Pluto is a joke, of course. Pluto is still out there, just as oblivious of what people call it as ever. But it was Mike Brown whose discoveries forced the astronomy community to address the anomaly of Pluto being classified as a planet. And he, despite his years-long quest to discover a tenth planet, despite the glory associated with being the only living discoverer of a planet, was true to his scientific convictions, and argued against his discovery, and therefore against Pluto, being considered a planet.
I will admit that I came into the Pluto controversy with a strong view of my own. I am one of those people who concluded many years ago, long before I ever heard of Mike Brown, that Pluto was not a planet. When it was discovered Pluto was thought to be quite a large object, and its designation as a planet made sense. But additional measurements showed it to be much smaller than originally thought,* smaller, in fact, than Neptune's moon Triton, itself believed to be a captured Kuiper Belt object. Further, it is locked in a orbital resonance with Neptune, where Pluto makes three orbits of the sun in the time Neptune makes two. So Pluto doesn't even orbit freely around the sun.**
I've heard Mike Brown talk about his experiences, and came to this book expecting a good read. He delivered. The astronomy is interwoven with Brown's life during the period of discovery. Some may object to this, but scientific discoveries are made by people who are concurrently living their lives. Too often what we hear about are the odd ducks who live only for their science. But most scientists aren't like that; most have lives beyond science, and their work is intertwined with their broader existence.
In this book we follow Brown from his early years in astronomy to his decision to look for another planet beyond Pluto. During his early, less than successful, attempts he meets, as a result of his work, the woman who will become his wife. We follow his courtship, marriage, and honeymoon as the search continues. The fruition of his search, the discovery of several large Kuiper Belt objects, overlaps the gestation and birth of his daughter.
During the time he is completing papers on his discoveries, and awaiting his daughter's birth, controversy erupts. A previously unknown astronomer in Spain appeared to have found one of his discoveries, and beat him to a public announcement. Initially gracious, Brown learns that the Spaniard apparently used the internet to learn where he had pointed a telescope to track the object, and used that knowledge to find the object and claim the discovery. This motivates a discussion of how science works, and the competing pressures to, on the one hand, announce discoveries so as to claim credit and, on the other hand, to get the facts together and write a comprehensive paper that adequately describes the discovery.
Having weathered that controversy, the Pluto issue explodes. Brown provides a comprehensive discussion of why it doesn't make sense to call Pluto a planet. He writes about the last time astronomers had this problem. (No, Pluto wasn't the first.) When Ceres was discovered between Mars and Jupiter in 1801 it was considered the eighth planet. (Neptune hadn't yet been discovered.) Then more "planets" were discovered between Mars and Jupiter. It was eventually realized that all these bodies couldn't be considered planets, and they ended up all being called asteroids. (The decision of the International Astronomical Union on Pluto made Ceres, like Pluto, a "dwarf planet".)
Similarly, Brown argues convincingly that Pluto is simply one of the larger bodies in the Kuiper belt. Its interaction with Neptune caused it to be discovered earlier than other large Kuiper Belt objects, but it is otherwise unexceptional. The book includes an excellent discussion on how scientists choose categories for objects, and why definitions matter.
All in all, this is a compelling book that captures the story of discovery and two controversies, as well as the reality--sometimes mundane, sometimes not--of how scientists actually live and work. And how can you not love a book where the astronomer gets the girl?
* In 1980 A. J. Dessler and C. T. Russell wrote a humorous one page paper that was published in EOS (vol. 61, no. 44, page 690) titled "From the Ridiculous to the Sublime: The Pending Disappearance of Pluto". In it they pretended to take the historical mass estimates of Pluto as being correct, did a mathematical fit, and predicted that Pluto would disappear in 1984. They then speculated on what would happen after it disappeared. This is available online, just search for it.
** I've heard the argument that Neptune could just as well be said to be in an orbital resonance with Pluto. While in a narrow technical sense that is true, saying it makes about as much sense as saying Neptune is in orbit around its moon Triton. Neptune is eight thousand times more massive than Pluto, and "captured" Pluto while itself remaining in a nearly circular orbit. Further, there are other Kuiper Belt objects in orbital resonance with Neptune, Pluto is simply the largest. When it comes to gravity size--or at least mass--matters.
- Reviewed in the United States on May 30, 2011After several years of curiosity regarding the declassification of Pluto as a planet, I happened upon this book and finally decided it would be worthwhile to get the full story. The book is a rather informative primer on astrophysics, putting everything in layman's terms so that anyone can follow along.
The book follows Mike Brown from his early days in astrophysical studies to his post-Pluto-killing days. At the beginning, he indicates that his main goal as a young scientist is to discover another planet in the solar system and establishes that whatever he finds should be bigger than Pluto so that his discovery is a planetary shoe-in. What ensues, however, are years of searching--through astronomical telescopes, physical photo files and digital photo archives--along with a host of roadblocks and failures. Brown makes it abundantly clear that searching the space around us is no small task.
What really helps this book is Brown's sense of humor, which helps to speed along the narrative. Other aspects going for it are: the clear explanations of astronomy; the brief history of planetary discoveries; an overview of astronomical telescope operations (who knew the waiting lists for use were so long?) and technology; the shady dealings of an Iberian research group.
Note that, because the timeline of the book is many years, part of the story necessarily covers how he met his wife along with the birth and raising of his daughter. Just when you think Brown's about to talk about his wife or daughter too much and risk losing his reader, he switches gears and gets back into the serious meat of his story. He's always on topic.
I definitely came away learning quite a bit from this book and had a good time in the process.
- Reviewed in the United States on July 24, 2015Mike Brown is a planetary scientist who, along with others, has discovered several dwarf planets, which, it turns out, are not planets at all -- they're something lesser and not necessarily only lesser in size.
What is a planet, anyway? That's a tough question, one that's boggled great minds and those of us who are simply curious about planets in general. The latest controversy (and, no, it's not the only one in history) came about not so very long ago when the experts began to wonder if Pluto really was a planet. The world certainly knew it as one but it had fallen on hard times when it was discovered over a number of years that it's just not very big. In fact, it's smaller than our own moon. In fact there are a number of moons that are larger than our own moon and yet no one calls them a planet. Well, that's simple: they're orbiting planets so they've got to be moons, right?
Maybe, kinda, well, hmmmm. The problem here is how to classify planets or moons for that matter. All of the planets are different. There are different kinds of planets -- terrestrial planets are named after Earth (terra) and include Mercury, Venus, Earth & Mars; then there are the Jovian ones, named after Jupiter (Jove). Terrestrial planets are rocky ones, Jovians are the gasbags -- Jupiter, Saturn, Uranus and Neptune -- and yet all of them are very different. Earth has oceans, the other terrestrials don't. Jupiter is bigger than all the other planets combined.
And now we have Dwarf Planets, but they decided that they are NOT really planets, though the word is included.
Very puzzling indeed. Real planets, like the original 8 (NOT Pluto, not anymore!) are the ones that have a "dominant effect" on the solar system. I would never argue that Jupiter is anything but a major player around here what with its powerful gravitational field and all. But Mercury? It's small, hard to see oftentimes, and poses very little threat. The lesser stuff, those non-planets like asteroids and such that may get hurled in our direction to cause mass destruction (if and when they hit us) or joy (like when they run into Jupiter) seem a much more dominant effect to me.
I could go on and on and on but I wouldn't help you understand. But I'm happy to report that this book is not only good at explaining these problems but is very readable and even well-rounded -- we hear a lot about his young daughter who was a newborn baby when he got involved with the Pluto controversy and who actually communicated through sign language before she could speak. And she likes planets. Now THAT's a good kid! And you'll also learn about just how hard it is to find out about those faraway bodies that Dr. Brown and his colleagues are discovering -- we still really don't know how big Pluto truly is (though we'll get a better handle on it New Horizons spacecraft has just reached it).
A very good book, indeed! Another related one is "The Pluto Files" by Neil deGrasse Tyson.

5.0 out of 5 stars The most interesting book I have read in recent years - with a terrible title
This really is a good book - please do not be put off by the terrible, rather immature title as I nearly was. If you are at all interested in the life of experimental science of astronomy today then this is very much the book for you. It rather brings up to date the account given in the first chapters of Fred Hoyle's 'the black cloud' - only this time it's real life not fiction. This account centres on the discovery in recent years by Mike Brown and his team of the large Kuiper Belt objects - in particular Eris, which is slightly larger than Pluto and in a previous era would undoubtedly been hailed as the fabled tenth planet. It details the tremendous amount of hard work involved and alongside this, Mike's love life, his marriage and birth of his daughter. An intriguing account is given of an attempt (by a very cunning subterfuge) of a foreign astronomer to steal and claim for himself one of Mike's discoveries. This well illustrates the perennial problem in science of getting results published without them being stolen by someone else - which must nearly always involve a certain amount of initial secrecy. In respect of this he also mentions the case of Bell-Burnett who is often regarded as having her contribution to the discovery of Pulsars rather underplayed by her supervisor. The last chapter is a account of the demotion of Pluto (and hence Eris) to the status of dwarf planets by the IAU - a move strongly supported (with very full and drawn out reasons) by the author despite the fact that the decision is not to his advantage.
Overall this really is very interestingly written with the personal nicely intermingled with the practical and the description of astronomical practices at just the right level for a layman to the subject. I wish there had been more of it. Good luck in the future Mike!

5.0 out of 5 stars Best book I've read in a long time.
The book makes losing Pluto as a planet a little less painful
