1. Yeah, it's not. Because it is not a planet or cannot be shaped like a planet.
What do you mean, not shaped like a planet? A planet shaped body can exist in an uncleared orbit. The process of clearing an orbit takes a bit of time. So you say that althought the "planet" exists it is not a planet until it stand alone in its orbit?
2. Freed from objects of the same proportions.
OK. What objects of the same proportions exist within the orbit of Pluto? Neptune is definitely not of the same proportion.
3. What means "potentially"? In the great time lapse it must have swallowed the objects or thrown them out of the orbit.
Suppose it is a young solar system. Is a planet not a planet until sufficient time has elapsed to clear its orbit? This makes the age of a body a criteria for it being defined as a planet.
4. First of all the definition is valid for solar systems. "Rogue planets" is not a term of the IAU.
Well it is not my fault the IAU is behind the times.
It is my opinion that the whole "cleared orbit" criteria was created for the express purpose of excluding Pluto, and like bodies, from being classified as planets. It serves no other useful purpose.
