Neptune is the eighth planet from the sun. It was discovered in 1846 and named after the Roman god of the sea. Neptune is the last planet in our solar system and orbits the sun at a distance of about 4.5 billion km. It takes Neptune 165 Earth years to orbit the sun and 16.1 hours to complete one rotation. Neptune has 13 known moons, with Triton being the largest, and five rings composed of dust and small rocks. Voyager 2 is the only spacecraft to have visited Neptune, providing data on its composition and atmosphere, which is similar to other gas giants with hydrogen and helium but also contains methane and ammonia.

3. History
• Urbain Le Verrier, Johann Gottfrie Galle,
Heinrich, AND Louis d'Arrest discovered
NEPTUNE WHEN September 23, 1846
WHERE at the Berlin Observatory.
• The planet was named after the roman
god of the sea NEPTUNE.
• PLANET NEPTUNES SYMBOL
• They say that our galaxy and universe
• Was created by the big bang theory
•

4. Solar System
• NEPTUNE IS THE EIGHTH PLANET
FROM THE SUN WHICH IS THE LAST
• NEPTUNE’S DISTANCE FROM THE SUN
IN KM AND AU IS 3.1 AU 4503000000
KM
• ONE ROTAION AROUND THE EARTH
TAKES 165 EARTH YEARS
• IT TAKES NEPTUNE 16.1 hours TO
ROTATE.

5. Planet Measurements
• A MASS OF 1024E24KG
62,525,703,987,421 km3 1.638 g/cm^3

6. Composition and Atmosphere
• The core of Neptune is composed of liquid
rock.
• The atmosphere of Neptune is similar to
all the large planets in the Solar System; it
mostly consists of hydrogen and helium,
with trace amounts of methane, water,
ammonia and other ices.

7. Moons
• NEPTUNE HAS13 moons
• Naiad Thalassa Despina Galatea Larissa
s/2004 n 1 Proteus Triton Nereid
Halimede Sao Laomedeia Psamathe
Neso ARE THE NAMES OF NEPTUNE’S
MOONS.

8. TRITON
• The most interesting moon is Triton, a
frozen world that is spewing nitrogen ice
and dust particles out from below its
surface.

9. ` Rings
• Neptune has five rings: Galle, Le Verrier,
Lassell, Arago, and Adams. Its rings were
named after the astronomers who made
an important discovery regarding the
planet. The rings are composed of at least
20% dust with some of the rings
containing as much as 70% dust; the rest
of the material comprising the rings is
small rocks.
`

10. Exploration
• VOYAGER 2 explored Neptune.
Voyager 2 is a 722 kg space probe
launched by NASA on August 20, 1977
to study the outer Solar System and
eventually interstellar space.

11. TO SURVIVE ON NEPTUNE
• To survive on neptune you would need
food oxygen water and protection
• The protection that u would be a space
suit and a air dome for living.
