• Neptune is named after the Greek god Poseidon.
• Poseidon is the god of the sea, Neptune was called Neptune because it was one important god who did not have a planet named in his honor.
• Neptune’s day is 17.24 hours which means it takes that long to spin around.
• The revolution of this planet takes longer than our lifetime, 165 years.
• The minimum distance from the Earth is 4.3 billion kilometers, the maximum is unknown.
• Neptune’s minimum distance from the sun is 4.46 billion km and the maximum is 4.54 billion km.
• It is the 8th planet from the sun and the 6th from earth.
• The density of Neptune is 1,638 kg/m^3.
• Neptune is the 4th largest planet.
• The diameter of Neptune is 49,500 km.
• The volume of Neptune is 6.25 x 1013 km3.
• The surface area of Neptune is 7.64 x 109 km2.
• The mass of Neptune is 1.02 x 1026 kg.
• The surface temperature is -218°C. During day= 350°C, Night=-170°C.
• Neptune's atmosphere is made of 80% molecular hydrogen, 19% helium, and 1.5% methane gas.
• Also has hydrogen deutoride(HD) and ethane(C2H6).
• There are 13 moons. They are Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Triton, Nereid, S/2002 N1, S/2002 N2, S/2002 N3, and S/2002 N4.
• Physical characteristics are molten rock and metal, and has a 47° rotational.
• Since its so far from the sun, it is really cold.• It is blue because the methane in the atmosphere
reflects the blue light from the sun back into space.
• It would be extremely windy and cold, earth has never had this much wind or coldness
• You would not last more than one week, there is no oxygen and a lot of harmful chemicals.
•The water is also unsafe and would kill you if you tried to drink it.
• Scientists today believe that life on Neptune is likely to not be possible because of the hostile winds and temperature.
• It is impossible because there is no atmosphere and oxygen for any life to breathe in.
• If there was a life form with a very large jacket and an oxygen tank, then possible life forms could live there.
What a BEAUT!
That’s
Pretty
neat!
