Members of the Society for the Preservation of Pluto as a Planet are dedicated to the proposition that Pluto has been and always should be considered a planet.
We support the original Draft Resolution 5 for GA-XXVI: Definition of a Planet that was presented by the IAU Planet Definition Committee in August 2006. In particular, we stand by the following points:
- A planet is a celestial body that (a) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (b) is in orbit around a star, and is neither a star nor a satellite of a planet.
- We recognize Pluto to be a planet by the above scientific definition, as are one or more recently discovered large Trans-Neptunian Objects.
