Final answer:

Pluto was reclassified as a dwarf planet in 2006 due to its inability to clear its orbit, distinguishing it from regular planets.


Explanation:

Pluto was once considered one of the outer planets, but when the definition of a planet was changed in 2006, Pluto became one of the dwarf planets. It is one of the largest and brightest objects among the dwarf planets alongside Ceres, Makemake, Haumea, and Eris. Pluto's reclassification was due to its inability to clear its orbit of smaller objects, leading to its categorization as a dwarf planet.
