Announcing the Top 10 Reasons Pluto Is - or Is Not - a Planet
FOR IMMEDIATE RELEASE
When New Horizons launches for Pluto tomorrow, January 17, 2006, it will begin a long journey to the last unexplored planet of our solar system. Or will it? Some scientists claim that Pluto is a Kuiper belt object, while many others, as well as much of the public, argue that Pluto is and always will be our ninth planet.
To celebrate the New Horizons mission and to draw attention to an interesting scientific debate, The Planetary Society issued a worldwide call for the Top 10 Reasons Pluto is - and is not - a planet.
The results are in!
Pluto is a planet because...[Pluto is] god of the Underworld, not god of the Underachieving World. Earl G, Radford, VA
Pluto is not a planet because...It's time to tighten our Kuiper belt and kick out the stragglers. Alan C, San Antonio, TX
"We narrowed down hundreds of entries from around the world to two lists of ten," said Bruce Betts, The Planetary Society's Director of Projects, "with more weight given to tongue-in-cheek responses than the seriously scientific...although some entrants managed to combine both."
Pluto is not a planet because...It doesn't appear to be so inclined. Lyford R, Ventura, CA
Even The Planetary Society's own Board of Directors is split on the question, with Chairman Neil deGrasse Tyson wanting to demote Pluto from the planetary ranks and other members of the Board staunchly defending Pluto's status. Read more on the Society's website about Pluto's status as a planet in essays by Tyson and the Society's Vice-President Bill Nye. The page also includes the complete lists of Top 10 reasons why Pluto is or is not a planet.
Pluto is a planet because...Look what happened after 40 years of arguing about the name of Planet 7 - we got Uranus. George C, San Antonio, TX
Whether one considers Pluto the last planet, the first Kuiper belt object, or something else entirely, the New Horizons mission will powerfully expand our scientific knowledge and the exploration of our solar system. Extensive mission coverage can be found at the Society's website.
