Pluto

             Ninety three years ago an astrologer noticed slight variations in
             the orbit of the planet Uranus.Then the search began for a ninth
             planet.Twenty five years later a startling discovery was made.
             The year was nineteen thirty when Clyde William Tombaugh had
             discovered a ninth planet beyond Neptune.The telescopic search initiated
             twenty five years years before by the man who first noticed these
             variations in Uranus's orbit Percival Lowell had been a success.4670000000
             miles (2670000000 kilometers) from Earth (at its closest point) a small
             yellowish colored marble was spotted.3666200000 miles (3666200000
             kilometers) from the sun the small planet had a diameter of one thousand
             four hundred twenty miles (2284 kilometers) making it the smallest planet,
             and yet the furthest from the sun.Its mass only point four percent of
             Earth's, and radius only eighteen percent of Earth's it is quite a small
             planet.It has a density of one hundred ninety nine percent almost twice
             Plutos environment is one of a cold desolate place.The tempeture
             ranges from a frigid negative two hundred twenty three to negative two
             hundred thirty three degrees Celsius which converts to negative three
             hundred sixty nine and negative three hundred eighty nine degrees
             farenhiet.Its extremely frigid tempetures are due to its obvious distance
             from the sun.Its atmosphere consists of nothing more than methane.Plutos
             thin atmosphere also contributes greatly to its extremely low atmospheric
             pressure only one hundred times weaker than that of Earth's. Its surface
             is made of very rocky material which is believed to be caused by the low
             tempeture, and atmospheric pressure.
             Pluto has only one natural satellite named Charon.Not so much as
             satellite a duplicate of Pluto its diameter is one thousand nine hundred
             ninety two kilometers (720 miles).Discovered in nineteen seventy eight
             this natural satellite is nineteen thousand kilometers...
