Neptune By: Taylor Radell Period 1 12/19/13
2
*The planet Neptune was named after the Roman god of the sea, known as Neptune How was the planet Neptune named? Neptune, God of Sea
3
*First planet to be discovered by the use of mathematics *John Couch and Urbain Leverrier calculated the coordinates of Neptune using mathmatical formulas. Johann Galte then discovered it in a Berlin observatory by the use of telescope on September 23, 1846 Discovery of Neptune
4
*Furthest planet from the sun (8th) *Distance from Sun - 4.5 billion km *Distance from Earth - 4.7 billion km Distances
5
Mass - 1.024 kg x 10 22 Volume - 62,525,703,987,421 km Density - 1.638 g/cm 3 Gravity - 36.6 ft Neptune would sink in water because the density of the planet (1.6 g/cm 3 ) is greater than the density of water (1.0 g/cm 3 ) Planet Measurements
6
*On Neptune, it takes 163.8 Earth years to revolve around the sun *On Neptune, it takes 16.1 Earth days to rotate on its own axis Orbit and Rotation
7
Neptune’s atmosphere is: *full of visible clouds and storms *made mostly of hydrogen, helium and methane *composed of two regions - troposphere and stratosphere Atmosphere
8
*Neptune’s average temperature is -353°F *Earth’s average temperatures are much warmer than Neptune, with an overall average of 40 - 60°F. Temperatures in Florida are usually around 60 - 80°F. Temperature
9
*Neptune is a gas giant, with its’ thick composition being made up of a combination of water, ammonia and methane *The internal composition of Neptune is very hot because of the energy leftover from its formation *Neptune’s surface has blue coloring because of the high amounts of methane in the atmosphere Composition/Appearance
10
*Neptune receives massive storms with high winds *Its’ atmosphere has dark spots and rapidly changing bright clouds that appear and disappear regularly *On Earth, sunlight drives our weather, so it is a mystery as to how Neptune gets enough power to generate such powerful storms being so far away from the sun Weather Storms on Neptune
11
*When the Voyager 2 went to Neptune, they discovered faint rings around Adams, the outermost ring. The faint rings are now known as Liberty, Equality and Fraternity. There are 5 huge rings like Adams. *Neptune’s rings are extremely dark and hard to see *Their composition is unknown Rings
12
*There are 13 moons revolving around Neptune *Triton is the largest moon and Neso is the smallest *6 out of the 13 moons are too dark to be seen from Earth, so they were discovered when Voyager 2 went to Neptune Moons
13
*Neptune is very icy! *Neptune has large quantities of water ice mixed in with hydrogen and helium from the atmosphere *There is little water on the cloud tops Water
14
*A person couldn’t live on Neptune right now *There is no liquid water on the surface and there is no energy resource for bacterial life to exploit *There could be possible life in the deep, deep core of Neptune where there is a possibility of liquid water, but it is too far inside Neptune to go to What would happen to a person on Neptune? Neptune’s Core
15
*Trition is Neptune’s largest moon *It is the only large moon in the solar system that rotates the opposite direction of Neptune, its “home planet” *Trition is so cold that most of its’ nitrogen is condensed as frost *Its’ surface includes smooth, volcanic plains and round pits formed by icy lava flows Something Special - Trition Triton
