NeptuneBy: Taylor RadellPeriod 1 12/19/13

*The planet Neptune was named after the Roman god of the sea, knownas Neptune

How was the planet Neptune named?

Neptune, God of Sea

*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

*Furthest planet from the sun (8th)

*Distance from Sun - 4.5 billion km

*Distance from Earth - 4.7 billion km

Distances

Mass - 1.024 kg x 1022 Volume - 62,525,703,987,421 km

Density - 1.638 g/cm3 Gravity - 36.6 ft

Neptune would sink in water because the density of the planet (1.6 g/cm3) is greater than the density of water (1.0 g/cm3)

Planet Measurements

*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

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

*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

*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

*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 getsenough power to generate such powerful storms being so far away from the sun

Weather

Storms on Neptune

*When the Voyager 2 went to Neptune, they discovered faint rings around Adams,the outermost ring. The faint rings are nowknown as Liberty, Equality and Fraternity. There are 5 huge rings like Adams.

*Neptune’s rings are extremely darkand hard to see

*Their composition is unknown

Rings

*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 darkto be seen from Earth, so they werediscovered when Voyager 2 wentto Neptune

Moons

*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

*A person couldn’t live on Neptuneright now

*There is no liquid water on the surface and there is noenergy resource for bacterial life to exploit

*There could be possible lifein the deep, deep core of Neptunewhere 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

*Trition is Neptune’s largest moon

*It is the only large moon in the solar systemthat 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, volcanicplains and round pits formed by icy lava flows
