It’s no longer a “planet.”

Find out why.


  1. I’m confused – earlier this week (?) didn’t some international astronomy group meeting in Austria declare that there were now 12 planets according to their new definition? Now there’s only 8? Can someone clarify please?

  2. 12 planets was a proposal by the IAU leadership; they expected it to pass. Instead that proposal was defeated and this one adopted.

    As a friend of mine pointed out, this could really mess up astrology.

    And with one fewer planet, planetary alignments are easier to achieve — meaning more Doomsdays.

  3. Geez, some alert person has already updated the wikipedia article for The Planets:

    In August 2006 Pluto was stripped of its status as a planet, demoting it to a dwarf planet, and Holst’s original decision was vindicated.

  4. Glen, Holst wrote The Planets in 1918. Pluto was discovered in 1930. That alert person made a mistake. Holst didn’t refuse Pluto, he just didn’t know about it.

  5. OK, I’ve read the article now. I didn’t realize that he had been asked to add to the work with the discovery of Pluto. Learn something new every day.
