Pluto Not A Planet Debate Rages On


Seems like people, like myself who are set in their ways, cannot adjust to demoting Pluto from being the ninth planet in our solar system…. Here is a variety of viewpoints:

Pluto is no longer a planet, according to a new official definition. Instead the icy sphere will be considered one of more than 40 “dwarf planets.”

Why is Pluto Not a Planet? The story of how Pluto lost its status as a planet. Pluto is no longer a planet, according to a new official definition. Instead the icy sphere will be considered one of more than…. Astronomers approve new guidelines under which distant Pluto is no longer defined as a planet — but the icy world’s advocates …

Pluto is still a planet. Only four percent of the IAU voted on the controversial demotion, and most are not planetary scientists. Their decision was immediately opposed in a formal petition by hundreds of professional astronomers led by Dr. Alan Stern, Principal Investigator of NASA’s New Horizons mission to Pluto. One reason the IAU definition makes no sense is it says dwarf planets are not planets at all! That is like saying a grizzly bear is not a bear, and it is inconsistent with the use of the term “dwarf” in astronomy, where dwarf stars are still stars, and dwarf galaxies are still galaxies. Also, the IAU definition classifies objects solely by where they are while ignoring what they are. If Earth were in Pluto’s orbit, according to the IAU definition, it would not be a planet either. A definition that takes the same object and makes it a planet in one location and not a planet in another is essentially useless. Pluto is a planet because it is spherical, meaning it is large enough to be pulled into a round shape by its own gravity–a state known as hydrostatic equilibrium and characteristic of planets, not of shapeless asteroids held together by chemical bonds. These reasons are why many astronomers, lay people, and educators are either ignoring the demotion entirely or working to get it overturned. I am a writer and amateur astronomer and proud to be one of these people.

Pluto Not a Planet, Astronomers Rule -by Mason Inman. Pluto has been voted off the island. The distant, ice-covered world is no longer a true planet, according to a new definition of the term voted on by scientists today. “Whoa! Pluto’s dead,” said astronomer Mike Brown, of the California Institute of Technology in Pasadena, as he watched a Webcast of the vote. “There are finally, officially, eight planets in the solar system.” In a move that’s already generating controversy and will force textbooks to be rewritten, Pluto will now be dubbed a dwarf planet. But it’s no longer part of an exclusive club, since there are more than 40 of these dwarfs, including the large asteroid Ceres and 2003 UB313, nicknamed Xena–a distant object slightly larger than Pluto discovered by Brown last year.
