All About
Pluto
By Lily
Pluto was named by a 11year old girl after the roman God of the underworld. There were only 8 planets in the solar system but then we all started thinking that there were 9. Now we are back to 8 planets with Pluto being a dwarf planet.

Pluto takes approximately 6.4 Earth days to spin once on its rotational axis. Pluto orbits the sun in a oval and most planets orbit the sun in a circle and sometimes cross over Neptune's orbit. Pluto's moon Charon orbits Pluto once every 6.4 days as well.This is called tidal locking. If you were to take a walk around Pluto, you would travel 4,494 miles (7,232 km). That is only about 1,400 miles farther than a trip across the United States, from Augusta, Maine to Los Angeles, California.
Pluto is so far away from the sun so it takes so long to orbit the sun it takes 248 years and on earth we only take 1 year because we are so much closer to the sun and we go in a circle and pluto goes in half circle and cross neptune's orbit.
The surface gravity on Pluto is about 1/12th the surface gravity on Earth. For example, if you weigh 100 pounds on Earth, you would weigh 8 pounds on Pluto.
Pluto atmosphere is always changing. The planet's atmosphere is affected by its temperature. The distance to Pluto from the sun varies significantly, ranging from 30 to 50 times the size of Earth's orbit. These changes in distance affect the atmosphere of the body. When Pluto is closer to the sun, the ices thaw and the atmosphere is thin. As it travels away from the sun, the gases re-freeze and the atmosphere is thicker.
Pluto is very cold! The temperature on Pluto ranges from -233 to -223 Celsius. For comparison, the coldest place on Earth, which can reach -126 Fahrenheit, would seem quite warm compared to Pluto. Many astronomers think that the surface of Pluto is covered with frost. it is far away from the sun so it will be the coldest plant and when it's closer it will be a little bit warmer and on earth it is much hotter but if you were to go to pluto you would freeze when it's -1 or -2 it's cold but imagine pluto you would freeze to death.
Pluto was known as the smallest planet in the solar system and the ninth planet from the sun. Today, Pluto is called a “dwarf planet.” A dwarf planet orbits the sun just like other planets, but it is smaller. A dwarf planet is so small it cannot clear other objects out of its path. Pluto is a dwarf planet because it's so small also pluto is the smallest plant in the solar system.
Pluto has 5 moons they're called Charon is pluto's closest moon. Other moons orbiting pluto are Kerberos, Styx, Hydra and Nix.
Charon: Discovered in 1978, this small moon is almost half the size of Pluto. Nix and Hydra: These small moons were found in 2005 by a Hubble Space Telescope team.
Kerberos: Discovered in 2011, this tiny moon is located between the orbits of Nix and Hydra.
Styx: Discovered in 2012, this little moon was found by a team of scientists searching for potential hazards to the New Horizons spacecraft flyby in 2015.
Scientists think that it’s possible that Pluto does have rings. This idea comes from the fact that Pluto has two tiny moons, Nix and Hydra. They’re just a few km across, and have very little gravity. So any micrometeoroid impacts on these moons will kick up material into orbit around Pluto.
If you were to live on Pluto you wold complete freeze it is so cold on pluto because it is so far away from the sun. It is very unlike that pluto would hold life.
Pluto is a dwarf planet because it is so small and far away from the sun and it is cold Pluto has not yet been visited by a spacecraft, but one is on its way. In January 2006, NASA launched the first mission to Pluto. This mission, called New Horizons, will reach Pluto in July 2015.
Clyde tombaugh discovered pluto in february the 18th 1930. you would need a good telescope to see pluto because it is very far away no one would be able to see it without a telescope.
Pluto is a very cold planet that humans would not be able to go to.
