Pluto


We just learned about the planet Neptune.

Pluto's not a planet, but it used to be!

For about 75 years, Pluto was one of the nine planets in our solar system.
Then someone changed what it takes to be a planet, and now Pluto is called a Dwarf Planet.

(from: wikipedia - dwarf planet)

Scientists saw that in outer space near Pluto,
there were other things near the same size floating around.

In an area called the Kuiper belt they found four other Dwarf Planets
so Pluto's not really alone out there, it's just not a big planet like the other eight!

The five Dwarf Planets are Ceres, Pluto, Haumea, Makemake and Eris.
