Answer:
Step-by-step explanation:
Personally, I think that scientists no longer considering Pluto to be the 9th planet is correct because planets and dwarf planets are different in size. Because they are smaller, dwarf planets lack the gravitational forces needed to pull in and accumulate all of the material found in their orbits. Each known dwarf planet in our solar system is actually smaller than Earth's Moon. I think Pluto should have not remained a planet because Pluto is small in size and does not fit in with the rest of the planets.
