Planet Measurements: Mass: 1.314*10^22 kg Volume: 6.39*109 km^3

Orbit and Rotation: Number of days to orbit around the sun: It takes Pluto 248.09 years to revolve around the sun. Perihelion: 4.4 billion km.

Equatorial Circumference: 4,493miles or 7,323 kilometers Mean density: 2.03-0.06g/cm^3 Gravity: It is 6.7 %of earths gravity

Aphelion: 7.38 billion km from the sun. Length of one day: 6 earth days and 9 hours.

Planet Appearance: Pluto looks small and grey, also looks very stormy.

Rings: Scientist say that Pluto is so far away that they do not know if that it has rings at all.

Atmosphere: Major gases: Methane Minor gases: Nitrogen and Carbon Monoxide.

Surface Condition: Wind Speeds:450 km per second or 1006621 mph. Temperature Ranges: -375 degrees Ferinheight Surface Pressure: 0.3 Pascal.

Weather: no one knows the weather because of how far it is, but they think its mostly covered with ice.

Water: Frozen water or ice is the only water found on Pluto.

Exploration: Unfortunately no exploration of Pluto has happened only by telescope on earth or in earths orbit.

Habitability:because Pluto is so cold humans wouldn't be able to survive on it.Also the water is frozen so you can not drink it.

Future human travel: There is not any room for you to do anything.

Terraforming:The temperature is to cold and there's not really any oxygen on the planet and there's not any room.

Cool facts: 1: Pluto was discovered in 1985 2:Pluto moves from the sun it freezes onto the surface 3:you would weigh a lot less then you do on earth on Pluto.
