__NASA__ has found a 4th moon of Pluto. First moon stated as a Charon, Hydra and Nix, the scientists have found a 4th possible moon apparently named as a "P4". Found on 6/28th in 2011. According to the research, 31 Earth days takes to rotate Pluto once, and it is estimated to be 13-34km across.=====

History
History of the Pluto is filled with interesting facts. It was first found in 1930/2/18ths by the Lowell Observatory. By the time it was found and until the Venetia Burney, an 11 years old girl from United Kingdom who named it as "Pluto", it was called as the "Planet X". In fact, it was found by the amateur astronomer as well which is pretty interesting. Furthermore since the 2003's research, scientists realized that the orbits of the Pluto is above the other major planet by 17 degree and also the location and the extreme small size of it allowed it not to be considered as a planet anymore. In addition, it has not cleared its orbit as well as it has extreme small mass and such a small gravitational force that cannot clear the path of it which eventually lead Pluto, not to be considered as a planet anymore. In 2006, NASA has launched the spacecraft in order to know how it is formed and what is inside it and by 2015-2016, they are expecting to see the results.

Mythology
Mythology that is related to the Pluto is that Pluto, the name of it is the name of the under world's god from Rome Myth. It was named Pluto since it is orbiting far away from our planet in such a dark place. It's natural satellite, "Charon"'s name is also related to its name and it will be introduced when you scroll down to the **Charon** Section.

Size

 * Mass**: 12500000000000000000000KG [0.0125KG x 10^24]
 * Volume**:7150000000KM^3 [0.715 x 10^10KM^3]
 * Radius**: 1195 KM
 * Density KG per m^3**: 1750
 * Gravity M per Second**: 0.58

Atmosphere Condition & Composition

 * Average Temperature**: -50K [-223 Celcius]
 * Scale Height**: ~60KM
 * Composition**: 90% of __Nitrogen__ and 10% of molecules including __Methane__ and __Carbon Dioxide__

Significant Features

 * Smaller than Moon
 * Sun light and Solar wind takes 5 hour to reach the 'Pluto'
 * Extremely Slow [1 Pluto year = 248 Eath Year]
 * No longer considered as a "Planet" and now considered as a "__Comet__"
 * Very Earth Like Atmosphere as Earth's atmosphere is also made of plenty of __Nitrogen__
 * Every couple hundred years, it is closer than Neptune
 * Kuiper Belt
 * 4 Moon = Charon - Hydra - Nix
 * Name "Pluto" is named by the 11 years old girl from United Kingdom
 * 1 Pluto Day = 6 Days and 9 Hours Earth Time
 * Can be close than Neptune. (Between 1979-1999)
 * Possible melted atmosphere when it orbits near the sun
 * Binary system = Rotating with "Charon" against each other

Future Plan
In 2005, Nasa have launched the spacecraft that heads to the Pluto, which will permits us to know their surface and resources in the Pluto by 2015. Spacecraft is named "New Horizons" and it was launched in 2006. In addition, there are 2 possible predictions about Pluto. One is that it is possibly covered by the "rocks and ices" and it is also possible to hit with Neptune and be gone according to it's orbit that is continuously coming close to the sun.

What don't we Know?

 * Resource
 * Absence of atmosphere -Most likely to have atmosphere in fact, no proofs



Orbital Period
6.387 Earth days to rotate Pluto

Date of Discovery

 * 1998 July 2nd**

History
History of the Charon is lacking in the length of the information as it was found pretty much recently in 1978 unlike Pluto. The reason why it was found so late was because the scientists thought it is just a star out of our galaxy and it was so tiny that restricted those scientists from realizing its existance. As the scientists found the relationship between the Pluto and the Charon, scientists realized that they are binary system and rotates toward each other. In 1985, scientists could determine Charon's size using stellar occlusion. This information may not be related to Charon, but there are some other extra moons that are rotating around these Pluto and Charon and they are also named from Greek/Rome Myth as their names are "Hydra" and "Nix" which are also a characters from a Greek and Rome Mythology.

Mythology
Mythology related to the Pluto's moon, the "Charon" is that the name of it is originated from the boatman who drives the souls of deads, to the underworld. It really matches with Pluto since both of its from myth related to underworld as they are binary system to each other.

Size

 * Overall Size**:About 1/7ths of the size of Pluto
 * Mass**: 1620000000000000000000KG [1.62 x 10^21 KG]
 * Volume**:902700000KM [0.9027 x 10^6 KM]
 * Radius**: 586 KM
 * Density KG per m^3**: 1.65G per cm^3
 * Gravity M per Second**: 0.278

Temperature

 * Average Temperature**: -50 Kelvin [-230 Celcius]

Significant Features

 * No Atmosphere
 * Internal Ocean
 * Layer of Ammonia Water
 * Icy Volcanoes
 * Lots of Water
 * Very close orbit with Pluto
 * Binary System (Very __Rare__)
 * Temperature close to __Absolute Zero__ that particles do not move at all.
 * Kuiper Belt

Future Plan
Just like Pluto, and as Charon is very close to Pluto, Nasa's launched spacecraft that heads to the Pluto, which will permits us to know their surface and resources in the Pluto by 2015, the "New Horizons" will also allow us to know lots of information about Charon as well. As the spacecraft goes near by those 2 binary systemed dwarf planets, we should be able to determine whether it has atmosphere or not, and it's exact compositions with it's resources.

What don't we Know

 * Atmosphere
 * Resources
 * Exact Temperature
