Which of the following celestial bodies is classified as a dwarf planet?
The answer is: Pluto.
Pluto was previously classified as a planet in the solar system, but in 2006 it was reclassified as a dwarf planet due to its small size and mass. Pluto is one of five known dwarf planets in the solar system and is the second largest known dwarf planet after Eris. Dwarf planets are celestial bodies that are too small to be considered planets, but are still massive enough to have a roughly circular shape.
