原文はこれ。括弧内を入れたものが5B、6B。Bが当初案に近く、修正案のAを先に票決する。 Resolution 5A The IAU therefore resolves that planets and other bodies in our Solar System be defined into three distinct categories in the following way: (1)A [classical] planet {1} is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit. (2)A dwarf planet is a celestial body that (a) is in orbit arount the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape {2}, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite. (3)All other objects {3} oribiting the Sun shall be referred to collectively as "Small Solar System Bodies" ------------------------------- footnotes {1} The eight [classical] planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. {2} An IAU process will be established to assign borderline objects into either dwarf planet and other categories. {3} These currently include most of the Solar System asteroids, most Trans- Neptunian Objects(TNOs), comets, and other small bodies. ------------------------------- Resolution 6A The IAU further resolves: Pluto is a dwarf planet by the above definition and is recognized as the prototype of a new category of trans-Neptunian objects. [This category is to be called "plutonian objects."]
