Introduction Neptune is the eighth planet from the sun. It was the first planet that was found by mathematical predictions. Neptune was discovered on September 23, 1846. Since Pluto was later not classified as a planet that makes Neptune the farthest planet from the sun. Neptune By: Krista Neptune is 4.5 billion kilometers away from the sun or 2.8 billion miles from the sun. Also Neptune is 4.3 billion kilometers away from Earth or it is 2.7 billion miles. The circumference of Neptune is 154,704.4 kilometers, the diameter is 49,532 kilometers. http://solarsystem.nasa.gov/planets/profile.cfm?Object=Neptune&Display=Facts&System=Metric Neptune is traveling at a speed of 5.4 kilometers a second. Measurements Measurements Measurements Measurements One rotation on Neptune takes 16.1 hours. One revolution takes 60,190 days or in Earth years it takes 164.83 years. http://planetfacts.org/planet-neptune-facts/ http://planetfacts.org/planet-neptune-facts/ Measurements The angle of Neptune's axis is 28.32 degrees. Measurements The effective temperature on Neptune is -214 degrees Celsius in metric in English it is -353 degrees Fahrenheit. Composition Neptune is made of , 1st the atmosphere which is 5-10% of the plant’s mass, 2nd extending up to 20% is the core at the very center which is made up of nickel and iron, next is the mantle a superheated liquid region. http://www.universetoday.com/21596/what-is-neptune-made-of/ Composition The atmosphere is mostly made with hydrogen and helium with a little bit of methane, the icy particles of methane create the blue of the planet: 80% hydrogen, 19% helium, with trace amounts of other ices like methane, ammonia, and water ice. http://moonphases.info/neptune-atmosphere.html Composition Neptune has 13 moons http://planetfacts.org/planet-neptune-facts/ Composition Neptune has 6 rings http://www.space.com/18920-neptune-composition.html Geology Neptune was formed with the basic buildup of a solid core followed by the capture of surrounding hydrogen and helium gas in the galaxy surrounding the early sun Geology The symbol is suppose to stylized representation of the god’s trident http://www.universetoday.com/21658/symbol-for-neptune/ http://solarsystem.nasa.gov/planets/profile.cfm?Object=Neptune&Display=Facts&System=Metric http://www.space.com/41-neptune-the-other-blue-planet-in-our-solar-system.html http://www.universetoday.com/21686/axis-tilt-of-neptune/ Space Exploration Neptune was named after the " god of the sea" http://www.universetoday.com/21658/symbol-for-neptune/ Space Exploration Neptune was discovered by Urbain Le Verrier, John Couch Adams, Johann Gottfried Galle, and Heinrich Louis d’Arrest http://www.universetoday.com/21621/who-discovered-neptune/ Human Exploration-history Voyager 2 flew by and discovered 6 of Neptune’s moon. Has been visited by only 1 spacecraft it was the last stop for Voyager 2 the spacecraft on its way of touring the solar system.In 1613 Galileo observed Neptune but he thought that it was just a star, Neptune was first observed by Johann Galle and Heinrich D'Arrest on September 23, 1846.On July 12, 2011 Neptune celebrated it’s first birthday since it’s discovery on September 23, 1846. http://www.spacestationinfo.com/neptune.htm Interesting Facts Neptune has it’s own heat source, it emits a quantity of energy 2.7 times greater than it receives http://www.planetfacts.net/Neptune-Facts.html Interesting Facts Neptune has very strong winds they can get up to 1,240 mph http://www.planetfacts.net/Neptune-Facts.html Resources The Planets by David Mcnab and James Younger Interesting Facts A year on Neptune spans two human lifetimes, 165 years.
