Question

why Pluto ruled out as a planet


I need short answer plz​

Answer 1

Answer:

The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”

Answer 2

Answer:

That is because Pluto is considered as a dwarf planed, and the size of it is too small that even satelites and big asteroids are bigger than it. Actually, Pluto is something that is never in use, it is only called planet because it's round in shape, rather nothing else
