 The proposed definition found support among many astronomers as it used the presence of a physical qualitative factor (the object being round) as its defining feature.Most other potential definitions depended on a limiting quantity (e.g., a minimum size or maximum orbital inclination) tailored for the Solar System.According to members of the IAU committee this definition did not use human-made limits but instead deferred to "nature" in deciding whether or not an object was a planet.
