Pluto

 = = P L U T O   =pluto was discovered by clyde w. tombaugh on the 18th of february 1930.  = pluto's average temperature is -223degrees celcius and averaging about 6 billion km from the sun.  pluto was once known as the smallest, coldest and most distant planet,  it is now a dwarf planet, and a member of a group of objects that make up a disc like zone beyond neptune called the kuiper belt. <span style="color: #f55b96; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;"> <span style="color: #c571df; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;"> pluto has 3 moons. the largest, charon is half the size of pluto but the other two hydra and nix are tiny only 50km and 60km in diameter. <span style="color: #f55b96; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">pluto takes 248 years to orbit the sun. <span style="color: #56dbfa; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">most of what we know we have learned since the 1970’s and more recently from the hubble space telescope <span style="color: #56dbfa; font-family: 'Comic Sans MS'; font-size: 14pt; mso-bidi-font-family: Arial; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">. <span style="color: #56dbfa; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;"> <span style="color: #6ff858; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">there has recently been considerable controversy about the classification of pluto.it was classified as the ninth planet shortly after its discovery and remained so for 75 years. but on august 24 2006 the IAU decided on a new definition of "planet" does not include pluto. pluto is now classified as a "dwarf planet", a class disinct from "planet". while this may be controversial at first people hope that this ends the essentially empty debate about plutos status so we can get on with the real science of figuring out its physical nature and history. <span style="color: yellow; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">the light from the sun takes nearly 6 hours to reach pluto. <span style="color: #c571df; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">sunlight is almost 2,000 times dimmer on pluto than it is on earth. <span style="color: #f55b96; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">every 228 years pluto's path dips inside that of neptune it then remains closer to the sun than neptune for 20 years, the next time this will happen will be in 2231. <span style="font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;"> <span style="color: #56dbfa; font-family: 'Arial','sans-serif'; font-size: 15pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">satelites-1 <span style="color: #f55b96; font-family: 'Arial','sans-serif'; font-size: 15pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;"> <span style="color: #6ff858; font-family: 'Arial','sans-serif'; font-size: 15pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">day-153.28hours=6.38 earthdays <span style="color: #f55b96; font-family: 'Arial','sans-serif'; font-size: 15pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;"> <span style="color: yellow; font-family: 'Arial','sans-serif'; font-size: 15pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">year-248 earth years <span style="color: #f55b96; font-family: 'Arial','sans-serif'; font-size: 15pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;"> <span style="color: #c571df; font-family: 'Arial','sans-serif'; font-size: 15pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">made of-70% rock,30% ice. <span style="color: #f55b96; font-family: 'Arial','sans-serif'; font-size: 15pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">diameter-2,300km <span style="font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;"> <span style="color: #f55b96; font-family: 'Comic Sans MS',cursive;"> <span style="color: #f55b96; font-family: 'Arial','sans-serif'; font-size: 14pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">
