The whole declassification flap is kind of silly, tbf. There was no coherent, scientifically useful definition of "planet" that would result in Pluto retaining the same classification as the eight current major planets, and certainly none that would result in having exactly nine planets (a number of trans-Neptunian objects would qualify). The fact of the matter is, Pluto has far more in common with other TNOs than the big 8).
"Minor planet" seems an appropriate designation.
