Pluto is a small icy "dwarf planet". Scientists are still unsure as to exactly what it's made of.
Pluto has not yet been visited by a spacecraft, but there's one on the way!
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."
Pluto used to be the farthest planet from the Sun (usually) and by far the smallest of the nine planets. Pluto is smaller than seven of the solar system's moons!
Now it's officially not a planet at all, just a "dwarf planet".
To date, not much is known about the planet, Pluto. Most of the information we have is largely based on speculation and inference. Its moon, Charon, helps scientists with various calculations relating to the properties and characteristics of Pluto.

Look for Pluto! Pluto can be seen with an amateur telescope - but it is not easy. You will need detailed charts and a few days of careful observations to actually find it.
