On February 18, 1930, the American astronomer Clyde Tombog discovered the ninth planet, Pluto in our solar system. An 11-year-old girl from England named it Pluto. There is a layer of nitrogen gas. The length of its orbit is about 5,913,520,000 kilometers from the Sun. This planet is located far away from the Sun, that's why the temperature of this planet is very low, about minus 229 degrees Celsius. The mass of this planet is 1.303e22 kg and its diameter is 2372 kilometers.
Pluto is a planet much smaller than the Earth. As the Earth rotates the Sun from west to east, Pluto rotates the sun in the opposite direction, from east to west. In addition to Pluto, Neptune and Venus also rotate the sun from east to west. It takes about 5 hours for light from the sun to reach here, whereas it takes only 8 minutes for light from the sun to reach the earth. It takes 248 years for the planet to orbit the sun once, which means that 248 years of Earth is equal to one year of Pluto. Since its discovery in 1930, Pluto has never orbited the sun.
