Detailed explanation-1: -The only difference between a planet and a dwarf planet is the area surrounding each celestial body. A dwarf planet has not cleared the area around its orbit, while a planet has. Since the new definition, three objects in our solar system have been classified as dwarf planets: Pluto, Ceres and Eris.
Detailed explanation-2: -For the most part, they are identical, but there’s one key difference: A dwarf planet hasn’t “cleared the neighborhood” around its orbit, which means it has not become gravitationally dominant and it shares its orbital space with other bodies of a similar size.
Detailed explanation-3: -According to the International Astronomical Union, which sets definitions for planetary science, a dwarf planet is a celestial body that-orbits the sun, has enough mass to assume a nearly round shape, has not cleared the neighborhood around its orbit and is not a moon.
Detailed explanation-4: -A dwarf planet is a small planetary-mass object that is in direct orbit of the Sun, smaller than any of the eight classical planets but still a world in its own right. The prototypical dwarf planet is Pluto.
