Characteristics of dwarf planet

Answer 1

1) has not "*cleared its neighborhood"

2) Small or undersized

3) Has sufficient mass (as do all planets)

*This means it is not strong enough to push the other planets away from it so they have their own places and they don't have to interfere with each other.

Answer 2

Dwarf planets are celestial bodies that orbit the sun, are not moons, and have not cleared their orbit of other debris. They are smaller than the eight planets in our solar system and are not considered full-fledged planets due to their inability to meet all the criteria set by the International Astronomical Union. Examples include Pluto and Eris.
