In 1906 Percival Lowell, who was a wealthy Bostonian who founded Lowell Observatory, started a search for a ninth planet in our solar system which he called planet X. But as Percival was looking for it he died in 1916 with no prevail, he had gotten pictures but planet X was very faint in the pictures, and so after 10 years the search for the planet began again but this time a 23 year old astronomer named Clyde Tombaugh who proved the existence of the mysterious planet in 1930; the planet was named Pluto after discovery.Pluto was called the smallest planet in our solar system and the ninth planet from the star, and most of it is made up of frozen nitrogen, methane, and carbon monoxide and probably has a small core with some metals. It got it’s name from an eleven year old girl named Venetia Burney who suggested naming it after the Roman god of death because it was most likely beyond freezing there that far away from the sun. Pluto also has five moons, Kerberos, Styx, Nix, Hydra, and Charon which is about half the size of Pluto’s. The small planet is only 1,400 miles wide making it slightly smaller than Earth’s moon. The orbital period for Pluto is 248 Earth years; and the small planet’s rotation period is six and a half Earth days.
