PLUTO AND CHARON

CHARON

• It is about half the diameter of Pluto and about eight times less massive. .
• New observations put Charon's diameter at between 750 and 753 miles.
• Charon is over 1000 times smaller than Earth
• Charon has very large amount of ice
• It is usually 212 degrees Farenheit and has no atmosphere

COMPOSITION

• Based on its density (2gm/cm) it is estimated that Pluto is made of 70% rock +30% ice water.
• Pluto's atmosphere is nitrogen, ethane, methane, and carbon monoxide.
• When far away these gases are frozen into ice and can be seen as bright spots in this picture.
• Size: Pluto's diameter is 2274 km with a mass of 1.27^22 kg.

TECTONIC ACTIVITY

• The inside of Pluto is warm and there may be enough energy in the core for movement.
• This type of interior motion has indicators on the surface of th planet.
• Surface plate tectonics that are related to earthquakes are big clues about motions within the Earth)
• These clues are important to search for now, because the surface of Pluto may still be exposed.

FORMATION

• Pluto and Charon were thought to have come togeather and collided in a similar way that we believe earths moon collided with earth.
• And reformed to form the moon

SUSTAINABILITY FOR LIFE

• you can't live on Charon because there's no atmosphere and is only half the size of Pluto which is much much smaller than our own earth.
• With temperatures close to -380 degrees Fahrenheit, Pluto is incapable of nurturing

DISCOVERY/ EXPLORATION

• pluto was discovered by the Lowell observatory in 1916 after lowell's death and his prediction of a Planet X
• Choron was discovered in 1978 at the us navy observatory
