The difference between planets and dwarf planets is that planets clear the area around their orbit, so they fill up more space, while dwarf planets have a large amount of space in either the forward point or backward point of orbit.
Dwarf planets don't have gravity
Pluto was officially called a "dwarf planet" on August 2006.
There are 51 known dwarf planets in the Solar System
Red and orange stars are coldest
Blue and white stars are the hottest
Yellow stars are medium
Each planet has something different than the other: Mercury is the smallest and Venus is the only planet the same size as Earth. Mars is the only planet to have water except Earth (that was a long time ago). Jupiter is the biggest planet in the solar system. Saturn is the lightest. Uranus is the coldest. And Neptune? It's the windiest.
Planets can be made up of two different things: Mercury, Mars, Venus and Earth are made of rock, and Jupiter, Saturn, Uranus and Neptune are made up of helium, hydrogen, ice and toxic water.
Moons are also known as satellites
Sometimes a moon is a month because of the new moon and old moon appearing every month
