How much would you weigh on Pluto?
Because Pluto is so small you would be very light if you visited. If you weigh 70 pounds on Earth, you would only weigh 4 pounds on Pluto.

The Dwarf Planet:
Pluto is smaller than 7 of the moons in the Solar System.  Because it is so small many scientists don't consider it a planet at all.  In 1999 a group of scientists attempted to redesignate Pluto as a comet.On August 24th, 2006 Pluto's status was officially changed from planet to dwarf planet. For decades children have been taught that there are nine planets in the Solar System. However, with this change, there are now only eight planets.
Pluto has never been visited by space craft.  Because we have never sent probes to this planet we know very little about it.

Moons:
Pluto has three moons. The largest is named Charon.  Charon is only slightly smaller than its parent Pluto.  For this reason Pluto and Charon are often called a double system.  The Earth and its moon Luna are sometimes considered double planets.
