How many planets have ever completed an orbit around the sun: 8, since Pluto has such a long orbital period that in its entire time as a planet it did not even finish a single one.
Pluto has completed millions of orbits around the sun.
At the time of the IAUs release of the definition of a planet, Neptune had not completed an orbit since its discovery, and yet they still called it a planet. Clearly, this weird and arbitrary statement that you have put forth did not matter.
I think it was sufficiently clear to just be a fun fact, not the implication that pluto did not complete orbits around the sun before it was discovered or whatever
Neptune has completed one though. So Pluto is the only planet to officially not complete an orbit while it was called a planet. It doesn’t affect whether it’s a planet or not, it’s just an interesting quiz question.
