Transcript of Pluto

By : Kera AND Cendall About the dwarf planet Pluto. Here's Some Pictures of Pluto The discovery of Pluto How Pluto got it's name. Distances: Orbit and Rotation Pluto was considered a major planet until August 24th 2006. Some scientist said it was to small to be considered a planet. They said it could be a moon. Other scientist believe that Pluto is a planet because it own moon. Pluto is the farthest planet (dwarf planet) from the sun. This makes it pretty cold. About the dwarf planet... Pluto got its name from a eleven year old girl named Venetia Phair who was learning about the Greek gods. Pluto was the name for the Greek god of the Underworld. Before the dwarf planet was discovered it had been called "X" because they knew it was somewhere but hadn't found it. # of days it takes to orbit the sun: 248 years
Perihelion: 4.4 billion kilometers (30 AU)
Aphelion: 39.53 (49.34 AU)
Length of day: a day on Pluto in earth days is 6 1/4.(so one day for us on earth is 6 1/4 on Pluto.) 144 hours Pluto ( The tiny planet) Pluto's density helps let scientist know that Pluto is most likely a mixture of 70% rock and 30% water and ice. Poor little Pluto is sad and was excluded from group pictures.
- Wise Words From Cera Pluto was discovered by astronomer Clyde Tombaugh on February 18, 1930. He worked at the Lowell observatory. Tombaugh was looking through the telescope and noticed a small white dot moving to the right and back in the two pictures he took. He knew it was the planet "X". Order from the sun: 9th if counted in the solar system. Order from the sun: 9th if counted in the solar system.
Distance from the sun AU: 99.31 AU
In km: 7.376
Distance from the Earth in AU: 28.6 AU
In km: 4.28 billion km Dwarf planet measurments 21 Mass: 12.5 x 10
Volume: 6.38726 x 10
Equatorial Circumference: 7.23195 x 10 km
Mean Density: 1750 (kg/m )
Gravity: 0.66 m/s , 2.2ft/s 9 3 3 Pluto's Apperance 2 2 Pluto's Moons... Icy and Rocky
A brownish Yellowish color
The surface is covered in ice and traces of methane and carbon dioxide Composition Core Composition Surface Composition Ice Phase 1, Ice Phase 2, Ice Phase 5, Rock, and Iron Charon: Is the largest moon orbiting Pluto. Was discovered in 1978 at the United States Naval station.

Nix: Is a small moon also orbiting Pluto. It was discovered by Max Mutchler and Andres Steffl , in the year 2005.

Hydra: Is the most natural satellite of Pluto. Its orbiting Pluto at 65,000 km away. Hydra's orbit is almost perfectly circular. Atmosphere Nitrogen 98%
Methane 2% Habitability Major Gasses Minor Gasses Surface Conditions Wind Speeds Temperature Ranges Surface Pressure Weather Water On Pluto? Explorations Future Human Travel Methane
Nitrogen Carbon Monoxide People can't live on Pluto or sustain life because of it's thin Atmosphere, temperatures ,and the frozen Methane covering the dwarf planet. Are very slow from the thin atmosphere and the only gas that can with stand the temperatures is helium which if the winds were high would mean that it would blow the helium out into space The weather on Pluto is unknown because there have been no probes. Pluto's temperatures are so cold that you really need to use Kelvin which is absolute zero tempature. Pluto ranges from 33 to 55 kelvin. *ignore the zero degrees sign it was just in the picture Terraforming We have never visited Pluto but we are planning to set a mission exploring the Dwarf planet and its moons. This is said to happen in 2015. No, there is no water on Pluto but there is said to be an underground ocean under ice on Pluto's moons Charon. ~3 microbar THE END Future travels to Pluto would be hard and not easy since it is already inhabitable . we couldn't be there long. The modifications we would have to make are heat, food and sunlight. We would need space suits to fit the climate and 1000 times more heat than we have now. We would have to make machines or something to cover our food supplies and daily visits from Earth to keep us supplies through out the years of habitation. We would most of all need a heat producer to keep us at normal body temperature.
