Answer 2

Answer:

Since 2006, per the International Astronomical Union's planetary criteria, Pluto isn't considered a planet because it hasn't cleared the neighborhood around its orbit of other objects. However, it does meet IAU's criteria for what constitutes a dwarf planet.

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.”
