The dwarf planet Pluto was discovered in 1930 by Clyde Tombaugh.
Pluto is the only planet in the solar system that has not been explored with a spacecraft. What is know about the dark, frozen world is the result of many years of work by scientists. It is thought that Pluto is made up of a mixture of rocks and several kinds of "ices". Scientists believe that most of the ices that make up Pluto are frozen methane and ammonia.
It depends on your point of view.... For hundreds of years, scientists have stated there are nine planets in our solar system... Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. In recent years scientists have 'relegated' Pluto to a 'minor planet' - as it is now considered part of the Kuiper belt, which is an area outside Pluto's orbit.
pluto has 4 known moons
It takes about 50 years from earth to Pluto
That depends on who you ask. Pluto technically has the longest year; each Plutonian year is equal to 247.7 Earth years. However, some scientists no longer consider Pluto to be a planet, and call it a "dwarf planet" instead. Since this decision was not actually binding, many people (including scientists) still consider Pluto a planet. If Pluto isn't actually a planet, then Neptune is the planet with the longest year (164.79 Earth years)
Pluto has four known moons, four times as many as the Earth.
Probably hundreds, since it takes years to get to Pluto.
To get from Earth to Pluto it takes 5763 km to get their.
It will reach pluto in 2014.
Pluto orbits the Sun in 14,164.4 Pluto days (90,613.305 Earth days, or 248.03 Earth years).
248.09 Earth years for Pluto to orbit the Sun
As of 2013, Pluto has been classed as a dwarf planet for 7 years.
