Neptune

By: Mallory Goodman

How did Neptune get it’s name?

When telescopes were invented many planets were discovered. When they discovered Neptune they saw it has a blue tint, because of this color they ended up naming the planet Neptune, after God of the sea.

• Johann Gottfried Galle, Heinrich Louis d’Arrest, Urbain Le verrier, John Couch Adams

• In 1846

Discovery

Neptune’s Measurements

Mass- 1.0241*10^26 kgVolume- 6.25257*10^13 km3 Density- 1.638 cm3 Gravity- 11.15 m/s²

Neptune would sink in water. Neptune’s density is more than water

Distances, Orbit & Rotation

Neptune’s distance from the sun is 4.503 billion kmDistance from earth is 4.4 billion km In order, Neptune is the farthest from the sun

It takes 164.79 years for Neptune to orbit the sun and it takes 16 hours 6 minutes and 36 seconds to rotate on its own axis

Atmosphere & Temperature

Neptune's thick atmosphere is made up of hydrogen, helium, and small amounts of methane (methane gives Neptune its blue tint)

Temperature ranges from -240 degrees to -330 degrees Fahrenheit, colder than earth and WAY colder then Florida

Moons and Rings

13 moons- Triton, Nereid, Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Hallmede, Psamathe, Sao, Laomedela, Neso

Neptune has 6 rings

Forms of water on Neptune and Weather

Neptune has large quantities of water ice mixed in with the hydrogen and helium atmosphere. There’s very little water at the cloud tops, but the percentage of water increases as you descend towards the heavier core

Neptune has some of the strongest storms ever, with winds that go up to 2,100 kmph. Earths highest speed in wind gusts is 253 mph in a tropical cyclone

Life on Neptune

When a human being enters Neptune’s atmosphere the trip won’t be long. Neptune’s atmosphere has so much pressure it couldn’t sustain human life, so the second a human enters the atmosphere they would instantly get crushed and suffocate
