87 Years of Pluto: Complete List of Signatories Who Signed 2006 Petition Rejecting IAU Definition




February 18, 1930, is a tribute to underdogs.

On this day, 87 years ago, 24-year-old Clyde Tombaugh, working at the Lowell Observatory with just a high school diploma, discovered planet Pluto using a blink comparator to move back and forth between two photographic plates of the same portion of the night sky, taken on January 23 and January 29 of that year.

Unfortunately, too often biased in favor of the controversial IAU decision, the mainstream media report that “Pluto was a planet for 76 years.” For many, ranging from top planetary scientists and astronomers to amateur astronomers to citizen scientists and members of the public, Pluto has been a planet—a known planet—for 87 years and counting.

Actually, Pluto has been a planet for four billion years and counting. It just took a long time for a late-coming species to the planet Earth to discover it.

Even ten-and-half years later, many people are unaware of basic facts about Pluto’s status—such as the fact that only four percent of the IAU voted on the definition that demoted Pluto, and most were not planetary scientists but other types of astronomers. In other words, they were NOT experts in this field and do NOT even study planets.

Just 333 of 424 IAU members present voted that dwarf planets should not be counted as planets, a misuse of the term “dwarf planet” as coined by Alan Stern, who intended the term to designate a third class of planets in addition to terrestrials and jovians.

Within several days, an equal number of professional astronomers and planetary scientists, about 300, signed a formal petition rejecting the IAU definition, a move that unfortunately got very little media attention.

For several years their petition and the names and affiliations of all signatories were posted online at http://www.ipetitions.com/petition/planetprotest/ . I am now reposting the wording of the petition as well as the names and affiliations of the signatories to keep this information available to the public.


“We, as planetary scientists and astronomers, do not agree with the IAU's
definition of a planet, nor will we use it. A better definition is needed.”

As noted on the original petition site, “In less than five days, the petition was signed by 300 professional planetary scientists and astronomers. The list of signatories includes researchers who have studied every kind of planet in the solar system, as well as asteroids, comets, the Kuiper Belt, and planet interactions with space environment. They have been involved in the robotic exploration of the solar system from some of the earliest missions to Cassini/Huygens, the missions to Mars, ongoing missions to the innermost and outermost reaches of our solar system, and are leading missions preparing to be launched. The list includes prominent experts in
the field of planet formation and evolution, planetary atmospheres, planetary surfaces and interiors, and includes international prize winning researchers.

“This petition gives substantial weight to argument that the IAU definition of planet does not meet fundamental scientific standards and should be set aside,” states petition organizer Dr. Mark Sykes, director of the Planetary Science Institute in Tucson, Arizona. “A more open process, involving a broader cross section of the community engaged in planetary studies of our own solar system and others should be undertaken.”

“I believe more planetary experts signed the petition than were involved in the vote on the IAU’s petition. From the number of signatories that the petition received in a few days, it’s clear that there is significant unhappiness among scientists with the IAU’s planet definition, and that it will not be universally adopted by scientists and text book writers. To achieve a good planet definition that achieves scientific consensus will require more work.” added co-sponsor Dr. Alan Stern, Executive Director of the Space Science and Engineering Division of the Southwest Research Institute.

For those who have not seen it, here are links to my February 18, 2013, blog entry, “Responding to the IAU: Pluto and the Developing Landscape of Our Solar System.” This is a point-by-point rebuttal of the IAU’s statement justifying the 2006 vote, posted on its home page (Content is identical on both sites): http://laurele.livejournal.com/2013/02/18/ and http://laurelsplutoblog.blogspot.com/2013/02/responding-to-iau-pluto-and-developing.html
