Planetary Society press release:
http://www.planetary.org/about/press/relea...t_Not__The.html - Is Pluto a Planet or Is It Not? The Planetary Society Seeks Top Ten Lists --- In honor of the launch of the New Horizons mission, the Society announces a call for the public to speak up and tell us: The Top 10 Reasons Pluto IS a Planet, or The Top 10 Reasons Pluto IS NOT a Planet Even The Planetary Society's own Board of Directors is split, with Chairman Neil deGrasse Tyson wanting to demote Pluto from the planetary ranks and other members of the Board staunchly defending Pluto's status. In the interest of impartiality and public engagement, The Planetary Society is calling for reasons on both sides of the issue. For the next eight days, visitors to the Society's website can share their reasons why Pluto should or should not continue to be ranked as one of the solar system's nine planets. The deadline for submissions is Thursday, January 12, 2006. The final Top 10 Lists will be released prior to the launch of the New Horizons mission. --- http://www.planetary.org/explore/topics/topten/ - Pluto Top Ten http://www.planetary.org/explore/topics/topten/enter.html - Enter the Contest! -------------------- - blue_scape / Nico -

Sorry to dredge up an older topic...however, there was talk of the 'is Pluto a planet' in another forum that I wanted to respond to but it would have been off topic.
According to the wikipedia entry for 'Planet'...The name comes from the Greek term πλανήτης, planētēs, meaning "wanderer", as ancient astronomers noted how certain lights moved across the sky in relation to the other stars. So therefor only Mercury, Venus, Mars, Jupiter and Saturn are 'Planets'. Since 'Planet' already has such a definition, let's move on. We need a word or words for rocky worlds and gaseous worlds. There should be a lower size limit to exclude debris. Our asteroid belt, and now TNOs/KBOs, make this more difficult as there's such a range within a given volume of space. I'm sure whatever the IAU does decide it will be unpopular with one group or another. I'm in favor of the word "Orbiter", as in "The orbiter Earth", "Third orbiter from the sun". -------------------- Eric P / MizarKey
