~	Pluto is a small, rocky planet. Scientists are still unsure as to what it's made of.
~	Pluto is the only planet that has not been visited by a spacecraft.
~	Depending on how far along it is in its orbit (path around the Sun), Pluto can be either the eighth or ninth planet. Pluto's orbit is kind of wacky, and it sometimes crosses in front of Neptune. When Pluto does this, Neptune is behind Pluto - hence, it is the eighth planet for a short time.
~	Pluto has one moon. It's called "Charon."
