Question

Pluto is not a part of the team planet. Why?​

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

After reclassification in 2005, Pluto is no longer classified as a planet because it: Pluto's gravity has not cleared its orbit of other matter and therefore it no longer fits the modern definition of a planet.
