Planet Measurements

• Masss: 102.4E24• Volume: 62,525,703,987,421 Km3

• Density: 1,640• Neptune would float because it is so light• Gravity: 11.15ft/s2

Composition of the atmosphere

• Mostly made up of hydrogen, helium, and some methane

• Methane is what makes Neptune blue

Distances

• 8th planet from the sun

• 4,496.6km from the sun

• 2,680,000,000 from earth

Orbit and rotatin

• It takes 60,190 days to orbit the sunThat is 164.8 earth years

• It takes .67 to rotate on its own axis Thats 19.1 hours

Temperature

• Average temp is -353 degres F

• It is much colder on Neptune then it is on earth and in florida

Composition and Appearance• Its is known as a Gas Giant

• The internal composition is a rocky core made up of iron and other metal

• The out side has a blue tint. It has a slushy ice and water layer. It is air and gassy and you cold not step foot on it with out starting to sink down.

Rings

Weather

• There are lots of clouds

• There are storms

• Neptune has the worst weather

• They have Cold icy brutal storms alot

Moons

• 13 known moons

• They all have names

• They were all discovered between 1846-2002

What would happen if a human traveled to neptune

• You would be crushed by the atmosphere• You would slowly sink to the center • And when you got to the core what ever was

left of you would burn up because the center is so hot

Neptune May Be a

Giant Diamond

• With Neptune's Gravity that squeezes on the planet, scientists found that Neptune's methane would decompose, with some of the hydrogen atoms breaking away and leaving the carbon to be compressed into pure, tiny diamonds.
