The ninth planet in our solar system is Pluto. It was discovered in 1930 by Clyde Tombaugh. Pluto is very small and far out from the Sun, so it is very dim in the sky. You can't see Pluto without a telescope.
We know little about this small planet. It is the only planet that has not been visited by a spacecraft. Pluto was named after the god of the underworld. It has one moon named Charon.
