Is Pluto a planet? It is no longer considered one, but some believe it should be

NASA's Alan Stern also disagrees with the IAU. In an interview with Forbes, he said all dwarf planets should be considered planets for a number of reasons—one being that the solar system contains so many asteroids that no celestial body has cleared the neighborhood of its orbit.

And that last is why the IAU definition is faulty.

Not that the IAU cares what I think, but I've never considered Pluto anything less than a full-fledged planet. Just because a group says it is not, does not change my view. It seems to me that any definition they try to attach to the debate, that someone will in all likelihood find some holes with which they can counter their decision. Appreciate the link nFA.

Agreed. A geophysical definition works with no problem: hydrostatic equilibrium creating a spheroid of too low mass to have ANY fusion. Any pseudoscientific definition that refers to orbit characteristics is going to be full of contradictions. Brown dwarfs have fusion of deuterium and lithium but not plain vanilla hydrogen.
