Explanation: 

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: -. During its formation, the dwarf planet could not pull in all the objects near its orbit and hence is not considered a planet. Pluto, Ceres, and Eris are some dwarf planets.

Detailed explanation-3: -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.

Detailed explanation-4: -The main difference between a dwarf planet and an asteroid is that a dwarf planet is large enough for its gravity to have forced it into a roughly spherical shape.
