Guest guest Posted December 27, 2007 Report Share Posted December 27, 2007 For Pluto, a Smaller World After All Astronomers' Reclassification Strips Ninth Planet of Status in Solar System By Shankar Vedantam Washington Post Staff Writer Friday, August 25, 2006; Page A01 Pluto the planet is dead. The baby in the solar system's familiar nine-planet pantheon, a favorite of schoolchildren everywhere, was disowned yesterday by the world's astronomers. Members of the 6th General Assembly of International Astronomic Union vote on a resolution for planet definition in Prague. The new guidelines made Pluto a dwarf planet rather than a " classical " planet. (Michal Cizek -- AFP/Getty Images) Defining 'Planets' The International Astronomical Union yesterday downgraded Pluto to a new category called " dwarf planet, " leaving only eight " classical planets " in the solar system. The organization also created a subcategory of dwarf planets - " trans-Neptunian objects " - to which Pluto belongs. It did not settle on an official name for the category. Pluto's failing? It isn't big enough and strong enough to push anyone around. That's what it takes to be a real planet, the scientists said. Only the eight " classical " planets are large enough to be dominant over smaller bodies in their path. Pluto's course through the heavens, by contrast, is under the sway of much larger Neptune. The former planet doesn't have even the consolation of a new title. In a series of votes, the astronomers narrowly decided against calling it a " plutonian object. " The term " pluton " was shot down, too. But they insisted that Pluto would still have stature -- it becomes a " dwarf planet " and the prototype of a new, as yet unnamed, subcategory of objects. The scientists said they will seek suggestions for a name from the public. The fight over Pluto's status at a meeting in Prague of the International Astronomical Union, the body that sets standards for the field, became a vicious battle that ultimately broke along scientific, linguistic and historical lines. The result was hailed by some as a victory of rationality over sentiment, but came as a huge disappointment to others, including the head of a panel charged with coming up with a new definition for " planet. " Owen Gingerich, a Harvard astronomer and historian, said the definition the group ended up with was a perfect example of " a horse designed by a committee. " He quoted a colleague in Prague as saying, " It demonstrates how belligerent and self-centered planetary astronomers can be. " The " dwarf planet " classification to which Pluto was relegated will potentially have dozens of members. But the scientists emphasized they were also carving out a subcategory for dwarf planets that orbit beyond Neptune, a group that currently includes Pluto and one other body. Astronomers acknowledged that one reason to create the special category is public sentiment against dumping Pluto in a large agglomeration of unspectacular objects. " The message to the public is we recognize Pluto as a prototype of a different kind of object, and that is more exciting than being one of the regular planets, " said Ron Ekers, outgoing president of the astronomers union. That reasoning was not well received in some quarters. " Pluto is a dwarf planet, but we are now faced with the absurdity that a dwarf planet is not a planet, " Gingerich retorted. " Is a human dwarf not a human? " The controversy over how to define Pluto began when scientists realized it is much smaller than it was thought to be when it was discovered in 1930. Early data indicating that it was large enough to disturb the orbits of Neptune and Uranus turned out to be observational errors.

Defining 'Planets' The International Astronomical Union yesterday downgraded Pluto to a new category called " dwarf planet, " leaving only eight " classical planets " in the solar system. The organization also created a subcategory of dwarf planets - " trans-Neptunian objects " - to which Pluto belongs. It did not settle on an official name for the category. As a result, astronomers felt there was something distinctive about Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. But like the late Supreme Court justice Potter Stewart, who said he could not define pornography but knew it when he saw it, the scientists found that coming up with a definition that would include only eight planets was surprisingly difficult. One option would be to call any round object orbiting the sun and larger than a certain size a planet. If that minimum size were arbitrarily set small enough to include Pluto, it would be a planet. But so would an even more distant object found in 2003 that is larger than Pluto, dubbed 2003 UB313, or, unofficially, Xena. Another possibility, advocated by Gingerich's committee, would have been to call any orbiting object sufficiently large for gravity to pull it into a round shape a planet. That would have included Pluto, Xena and Ceres -- a object long considered an asteroid that orbits between Mars and Jupiter -- and perhaps others. This definition would have preserved the status of the eight " classical " planets by calling the smaller objects " plutons. " But geologists objected, saying the word " pluton " hadalready been claimed -- in geology, it is the term for magma that works its way into rocks. Yesterday, astronomers who focus on dynamical properties -- how planets influence their surroundings -- won the day: Because the eight classical planets are relatively large, they dominate their orbits, sweeping smaller objects before them. " Either of these definitions is technically good, " said Ekers, referring to the Gingerich definition and the one finally adopted. " One would have been easier for describing to children and the public, and the resolution which is passed is fine for scientists but is a little more difficult for the public. " Other astronomers remained divided. Andrew Cheng, Harold F. Weaver and Karl Glazebrook of Johns Hopkins University said the new definition about planets being able to clear their neighborhoods of other objects is muddled and confusing. But colleagues William P. Blair and Richard Conn Henry said demoting Pluto makes sense. Astronomer Mike Brown, who helped discover Xena and would have stood to gain fame from Gingerich's original definition, said the astronomy group had come up with the right decision. " A mistake was made, and science has corrected the mistake, " said Brown, of the California Institute of Technology. But Gingerich, who is also a historian, said astronomers had blown it by ignoring public sentiment and the historical significance of Pluto: " We are an expensive science, and if we don't have public support, we are not going to be able to do our work. " How the Facts Align As Pluto Is Demoted, Some Look for Scientific Clarity By Michael Alison Chandler and Mary Otto Washington Post Staff Writers Friday, August 25, 2006; Page A07 Beneath the wings of the space shuttle Enterprise in a cavernous hangar at the National Air and Space Museum's Virginia annex, space exploration took a deeper turn into the unknown yesterday with the news that Pluto will no longer be considered a planet. Without a scientist or exhibit to explain the reclassification of the cold, distant entity long known as the ninth planet, young science enthusiasts turned to their only source of information for clarification: their parents. Dominic Santoro, 7, of Reading, Pa., views a model of the solar system in the Outer Space Place at the Maryland Science Center in Baltimore. (By Robert A. Reeder -- The Washington Post) The International Astronomical Union yesterday downgraded Pluto to a new category called " dwarf planet, " leaving only eight " classical planets " in the solar system. The organization also created a subcategory of dwarf planets - " trans-Neptunian objects " - to which Pluto belongs. It did not settle on an official name for the category. " But, why can't it be a planet anymore? " was the first thing 11-year- old Maria Lomax of York, Pa., wanted to know. " Well, if you get more scientific research, then the scientists can change what they think, " Becky Lomax replied. " But if it's not a planet anymore, then what is it? " chimed in Sarah Lomax, 9. Becky Lomax, who home-schools her children, said she will have to investigate. " We just did the solar system last year, " she said. " I guess we have to revisit it. " At the Rock Creek Park Nature Center and Planetarium in Washington, in the midst of a knot of children who were studying sunspots through a telescope, 6-year-old David Lieberman of Bethesda was incredulous when his mother informed him that Pluto had been reduced to " dwarf " status. " It has to be considered a planet because it circles the sun, " he said. " Pluto's not even the farthest planet. " Sometimes, he has learned, Neptune and Pluto switch places. Erasing Pluto's planetary designation from the galaxy of science textbooks, encyclopedias and educational software will be no small task. For years to come, students may puzzle over Pluto. Next to an astronaut suit display at the museum annex in Chantilly, 5-year-old Sam Hennig of Arlington wondered what Pluto might be if not a planet. " A star? " he asked. " A meteor? " The three-foot-tall towhead said he has learned about Pluto from the library books. " It's dark and cold, " he said. And it's so far away that " the sun looks like a little dot from there. " Yesterday, he knit his brow over what he doesn't know. " If Pluto isn't, well, " a planet, he asked, " will it still be part of the solar system? " For 4-year-old Benjamin Meman of Frederick, whose interest in outer space has not developed far beyond Martians, the loss of Pluto means one fewer magnet on the refrigerator. Defining 'Planets' The International Astronomical Union yesterday downgraded Pluto to a new category called " dwarf planet, " leaving only eight " classical planets " in the solar system. The organization also created a subcategory of dwarf planets - " trans-Neptunian objects " - to which Pluto belongs. It did not settle on an official name for the category. For Ben Kranner, 13, of Madison, Wis., one fewer planet will require a new planetary mnemonic device. " 'My very excellent mother just served us nine pancakes' will become 'My very excellent mother just served us nine. . . .,' " he said. " It doesn't make any sense. " His father, Paul Kranner, who was studying a panoramic image of Mars, took the news harder. " I didn't think they would actually decide that, " he said of the scientists. He said his son's generation has not inherited the same keen interest in outer space as his own. " In the 1960s and 1970s, space was really cool, " Kranner said. " If there was an Apollo landing, they would cancel school or they would roll a giant TV into the cafeteria, and everybody would watch it. But back then it was just Apollo and the moon, and that was it. Pluto used to be one little blur in the telescope. " Now there are bigger telescopes and more blurs, he said, and there may be 600 planets or there may be eight. With each discovery, he said, " They'll add another sentence to the book.
