    “Non-planet” Pluto gets new class

    “Plutoid” is the word of the moment for astronomers.

    It is the new classification that has been sanctioned for the object that was formerly known as the “ninth planet”.

    It is nearly two years since the International Astronomical Union (IAU) stripped Pluto of its former status as a “proper” planet.

    Now an IAU committee, meeting in Oslo, has suggested that small, nearly spherical objects orbiting beyond Neptune should carry the “plutoid” tag.

    I couldn't forget them because I had never heard of them, but now:

    (How does that work again, click a troll's profile, and then click "Ignore User". Yeah, that's it.)

    Last night I went through my stack of Astronomy mag’s and I came to a story, “The Problem with Pluto”. It was about how the head of the IAU had arbitrarily decided that Pluto should be downgraded to a minor planet and the uproar that followed. The story was from 1999.
    Of the 2412 members of the IAU, 424 voted to consider the status of Pluto. In August 2006, a debate was held and the decision was made to make Xena (Eris), Ceres, and Charon planets and keep Pluto as a planet. This wasn’t acceptable to a minority of the IAU, so an unprecedented second debate was held within a week and the term “dwarf planet” was created to name a class of planetoids that included the above, several other objects and of course Pluto. Immediately, a group of three hundred (no I can not name them all) members of the IAU said that they would never agree with this decision. Ever.
    Astronomers can tell you about dwarf galaxies (they are still galaxies) and white dwarf stars (they are still stars), so the term “dwarf planet” has been ditched for the term “plutoid”, because some people just do not want to have Pluto as any kind of planet. People with a point of view that they want to express can get rewarded for persistence. Especially if they continue for years to try and find a way to get what they want. Usually they just form a political group, but not always.
    Fortunately, people who abuse whatever authority they have can be replaced and next year there may be a reversal of this confusing nonsense. Don’t cross Pluto off yet.
