The three requirements for planet status are as follows.
The object has to stabilize its orbit.
The object needs to clear debris out of its orbit.
The object needs to be a certain size and shape.
Pluto is 0 of 3 on this. It’s orbit goes above/below the solar plane that the other planets follow. There is still a large amount of space rocks in its orbit, and finally its a lumpy potato more than a planet.
The size issue and debris issue can fix each other, but at the end of the day, it’s just a dwarf planet for now.
