Answer:
The major property that differentiates a dwarf planet from a major planet is that dwarf planets are not the dominant objects in their orbits and have not cleared the neighborhood around their orbits.
Step-by-step explanation:
The major property that differentiates a dwarf planet from a major planet is that dwarf planets are not the dominant objects in their orbits and have not cleared the neighborhood around their orbits. In other words, dwarf planets are smaller and less massive than major planets, and they do not have the gravitational force necessary to clear their orbits of other objects, such as asteroids and comets. This is one of the criteria used by the International Astronomical Union (IAU) to define what constitutes a planet, and it is why dwarf planets, such as Pluto and Eris, are considered a distinct category of celestial objects.
