Small and Far Away Pluto was once called a planet. Not now. Today it is a dwarf planet.

Dwarf planets are small. They orbit the sun. Rocks orbit with them.

Dwarf planets are icy. They are far from the sun. It takes Pluto 248 years to orbit the sun!

Pluto is red and gray. It has a big moon. It is Charon.

What are other dwarf planets? Ceres is gray. It has craters.
