Dwarf planets are celestial bodies that orbit the Sun and are similar to regular planets but do not meet all the criteria to be classified as such. They are not large enough to clear their orbital path of other debris, which is one of the key differences from full-fledged planets. Examples of well-known dwarf planets include Pluto, Eris, and Haumea. These fascinating objects are primarily found in the Kuiper Belt, a region beyond the orbit of Neptune. Dwarf planets can vary in size and composition, and they often have unique characteristics, such as moons or rings, making them intriguing subjects of study in planetary science.
