One year on Pluto is 248 earth years. And one day on Pluto is the same as 6 days on earth. Scientist estimate the temperature to be -200 degrees celcius. (-328 degrees ferenhight). It is so cold there because almost no heat from the suns rays reach the surface. Pluto's surface is 50 to 75% rock and the rest of it is ice. The atmosphere appears yellowish/redish. There is a thin layer which is 98% nitrogen, the remaining is carbon monoxide and mostly methane.

  * The average distance from the sun is 5.9*10^9 km.

  * Size: Mass -1.27*10^22 kg

  * Diameter- 2,274 km

  * Density- 2,050 kg/m^3

  * The only Planet never vistited by a probe

  * Astronomers believe bright areas may be shifting fields of nitrogen ice, while the darker areas house methane ice covered by interaction with sunlight.
