// Who Discovered our planet :// //Johann Gottfred// //When:// //September 23, 1846// //How:// //There were calculations made very precise, which were of by 1 degree.// //Where:// //Berlin Observatory//

//Distances:// //Order from the sun: 8th planet// //Distance from the sun: 28 billion miles// //Distance from earth: 4.4 billion km.//

//Planet Measuments:// //Mass: 310 kilograms// //Volume: 6,254 km.//

//Orbit and Rotation:// //Number of days to orbit around the sun: 60,190 earth days// //Perihelion: 4.45 billion km.//

//Equatorial Circumfrence:// //Mean Density:// //49,528 kg/m^3// //Gravity: 11// //Aphelion: 4,553,946,490 km.// //Length of 1 day: 17hours and 6 min.//

//Planet Appearance:// //Neptune is said to be blue, yet it is just the refelection of light. It also appears to be blue because of the traces of methane found in the planets clouds. It is made up of various 'ices' and rocks on it's surface Neptune has dark spots because wind storms form constantly on its surface.//

//Rings:// //There are 8 faint rings. They are made up of hydrogen,helium,and methane. Rings are a hue of faint blue.//

//Satellites:// //There are 13 moons around neptune. Their names are Naiad, Thalassa, Despina, Galatae, Larrissa, Triton, Nereid, S/2002^n1, S/2002^n2, S/2002^n3, S/2002^n4, S/2003^n1, S/2003^n2.// //Composition:// //Core Composition: Solid and Liquid rock, then layers of hydrogen, helium, and water// //Surface Composition: Hydrogen- 80%, Helium- 19%, Methane-1%//

//Atmosphere:// //Major Gases: Helium& Hydrogen// //Minor Gases: Methane// //Surface Condition:// //Wind Speeds: 1,200 mph// //Temperature: Lowest 55 kelvin, = -218 degrees// //Surface Pressure: 11 m/s^2//

//Water Forms:// //Frozen Water in the core and traces in the clouds.//

// Exploration: // //Voyager 2 1989 - Discovered 6 of Neptune's moon//

//Habitability:// //The person (people) would be surrounded by dangerous and toxic gases and suffocate//

//Future Human travel:// //There is no oxygen and source of human food, water is scarce and no homes could be set up.//

//Terraforming:// //Oxygen and source of food would be needed and so would water and source of habitat.//

//Weights:// //Brea- 123 lbs. and Blake- 84 lbs.//
