Pluto means:
To the Romans Pluto was thought to be the god to whom all men must eventually go. They believed him to be the god of the underworld. His name in Greece was Hades (KidsAstronomy.com).
Pluto is the smallest and furthest planet from the Sun. It is considered a dwarf plant. In fact recently they demoted it from the title of being a planet, but we are including on this tour anyways.
Pluto is far from the Sun that it takes hours for the Sun to reach it. Because of this Pluto is freezing. Substances such as oxygen and nitrogen, that are vital to human life, freeze on Pluto. Size wise Pluto is only about two-thirds the size of our moon.
Due to the fact that Pluto is so small and located so far away it has never been visited by a space craft and therefore the knowledge we have on it is very limited.
Fun Facts About Pluto:
Pluto is so far away, that no satellites have ever been sent there. This means that we have no good pictures of it. All we can do is guess what is must look like. The picture above was taken by the Hubble Space Telescope. It is the most detailed picture we have (KidsAstronomy.com).
