Pluto is a frigid ball of ice and rock that is completely frozen and covered with a layer of frozen nitrogen and Carbon Monoxide. It is the the ninth and smallest planet in our solar system.

It was discovered by Clyde Tombaugh on February 18, 1930, at Lowell Observatory in Arizona. Tombaugh died in 1997. Pluto is 1,473 miles in diameter. That is about one fifth the diameter of Earth. Every Pluto day takes 6.39 Earth days. For every year it takes Pluto 247.47 Earth years.

It would take 500 Pluto's to equal Earth's mass. The surface temperature on the surface of Pluto ranges between -302 to -369.

The name comes from Greek Mythology - the God of the Underworld - Hades. The maximum distance from the sun is 2.66 billion miles. Pluto is made up of 70 % rock and 3 % water. The mean density is 9m/cm^3 2.05 The rotational period (days) is 6.3872. The orbital Period (years) is 248.54. It's atmosphere is made of methane and nitrogen. The average distance from the sun is 5,916,000,000 km. Pluto's mass is 13,000,000,000,000,000,000,000 lb.

Pluto doesn't fit into the terrestrial planets or the gas giants. It's more similar to objects called the Trans-Neptune objects (TNO). To get to Pluto would take a lot longer than just a normal four hour car trip. Light travels 186,000 mps (Miles Per Second) and it still takes 4 hours for Pluto's light to reach us ! It took the Voyager 20 years to get near Pluto. In about 2015, scientists hope to launch the Pluto -Kulper Express. Nobody can live on Pluto because it's too cold. Also, pluto has water, but under a bunch of poison stuff. There was only one mission to Pluto called the New Horizons. The launch date was 1/16/2006. The arrival date was 2015. The type was a flyby. The spacecraft will come within 11,000 KM of Pluto and 20,000 KM of Charon during
the six month period.

Pluto has 3 moons, those moons are: Charon, Nix (S/2005p1) and Hydra (S/2005P2). Charon is probably covered in ice and no atmosphere at all. Charon is 1,172 in diameter, Nix is about 150 km across. While Hydra is even smaller with 100 km. It takes about 30 days for Nix to orbit Pluto while Hydra orbits Pluto every 28 days.
