Final answer:
The statement is true.
Step-by-step explanation:
Pluto, along with Ceres, Haumea, Makemake, and Eris are all properly classified as dwarf planets. The primary difference between planets and dwarf planets is not just about their size, but also, about their ability to clear their orbit.
Specifically, a dwarf planet has not cleared the neighborhood around its orbit, whereas planets have. This is a key criterion defined by the International Astronomical Union (IAU) for a celestial body to be considered a planet.
