All About 

Neptune

By Sam M

Neptune: Neptune means Roman mythology, Greek god Poseidon

Position in the Solar System: Neptune is 8th in the Solar System. It is beside Uranus and on the other side is Pluto. It orbits 4.498 billion kilometers from the Sun.

Rotation on its Axis: Neptune’s day is only 16 hours unlike Earth which has 24 hours in a day.

Size: Neptune is almost 4 times the diameter of Earth which is about 12,500 wide.

Gravity: Neptune has 11.15 m/s2 of gravity. I would weigh about 68.76 kgs on Neptune.

Orbit: It takes 165 Earth years for Neptune to orbit the Sun.

Atmosphere: Neptune's atmosphere is made up predominately of hydrogen and helium, with some methane. The methane is part of what gives Neptune its brilliant blue tint, as it absorbs red light and reflects bluer colors.

Temperature: The temperature on Neptune is always -218 degrees Celsius.

Composition of Your Planet and its Appearance: Neptune is the last gas planet along with Uranus, Jupiter and Saturn.

Moons: Neptune has 14 moons. They are called Triton, Nereid, Larissa, Proteus, Naiad, Thalassa, Galatea, Despina, Laomedeia, Halimede, Sao, Neso, Psamathe and S/2004 N 1.

Rings: Neptune has 3 main rings that are very thin and dark, but there are several others.

How Would a Human Being Fare on Your Planet: They could only be in Neptune's atmosphere. Neptune is gas down as far as the core and so there is technically no surface. Therefore, a human could never be 'on' Neptune, on 'in' its atmosphere, and a human on Neptune would be a bit heavier, but not to much. There isn't anything to eat. It would be colder than most could imagine. Cold enough that nitrogen, which is an atmospheric gas here on earth, would be a liquid on Neptune. A person couldn't wear enough clothing to be protected outside on the surface. Any building there would have to be insulated in a way no building contractors here on earth have ever done. You'd need some serious heat in that building. Very serious heat. Oh, and with wind on Neptune ripping at something like 2100 kilometers per hour, it would be really tough to keep a structure in one place.

Something Special: Neptune is one of 4 gas giants. The storms on Neptune are 3 times as fast as the Hurricanes on Earth. Neptune is tilted 28.32% degrees, unlike Earth which is 23.5% tilted. Space crafts have never landed on Neptune and they probably will never because Neptune is gas so the Space crafts will fall right through.

Discovery of Your Planet: Neptune was discovered by mathematics and discovered by, John Couch Adams, Johann Gottfried Galle and Urbain Le Verrier in September 23 1846.
Your personal opinion: Overall, I think that Neptune is a damn cool planet and it is my favourite planet.
