Why isn't Pluto a planet anymore? State all four reasons.
* Pluto orbits its moon; it doesn't have gravitational dominance.
* The way Pluto orbits around the sun, it's not in the same plane as the other eight.
* Pluto doesn't fit with the outer planets, but it is in their territory.
* If Pluto is a planet, then other objects should be considered planets too. It made scientists think deeper about Pluto.
In simple words, what is the Kuiper Belt?
The Kuiper belt is a region shaped like a doughnout and made up of planetesimals (baby planets), ices (anything that freezes), and rocks.
