|In astronomy mythology, Pluto was thought to be the god to whom all men must eventually go. Romans believed him to be the god of the underworld. His name in Greece was Hades.
How much would you weigh on Pluto? Because Pluto is so small you would be very light if you were on it. If you weigh 70 pounds on Earth, you would only weigh 4 pounds on Pluto!
Pluto is the only planet that has never been visited by a space craft. Because we have not yet sent probes to this planet we know very little about it.
Pluto has one moon named Charon. Charon is only slightly smaller than Pluto. For this reason Pluto and Charon are often called double planets.
Because Pluto is so small, many scientists don't consider it a planet at all. In August 2006, the International Astronomical Union (IAU) decided that Pluto was not a planet equal to the other eight planets in our solar system, and called it a dwarf planet.
