Planet Neptune
Neptune, the 8th planet from the Sun and nearly a twin of planet Uranus, is the fourth-largest planet by diameter and the furthest planet discovered so far in our solar system. Planet Neptune gets its name after the Roman god of the sea. It is a gas giant.

How many earth days does it take to go from earth to Neptune?
It would take over 16,000 Earth days, or around 44 Earth years, for a spacecraft to travel from Earth to Neptune at its average distance from Earth. The actual time would depend on the speed and trajectory of the spacecraft.
Neptune's famous moon is Triton. It is the largest of Neptune's 14 moons and is notable for its retrograde orbit, meaning it orbits Neptune in the opposite direction of the planet's rotation. Triton is also geologically active, with cryovolcanism and icy plumes observed on its surface.
Does Neptune gas planets have erosion?
Neptune is a gas giant composed mainly of hydrogen and helium, so it does not have erosion like rocky planets. Neptune's atmosphere is very dynamic, with strong winds that constantly shape and alter its cloud formations. The atmosphere also has powerful storms, such as the Great Dark Spot and the Scooter, which contribute to the planet's ever-changing appearance.
How long would a person live on Neptune?
That is actually a fascinating question.
It would be a race between which would kill you faster, the intense cold of negative 373 degrees Fahrenheit atmospheric temperature, or the poisonous atmosphere of hydrogen, helium and methane.
There is no solid surface, and no possible sources of food or potable water - but that's irrelevant, as you'd be dead before that could become an issue.
As liquid nitrogen is used to flash freeze organic food stuffs, and occurs virtually instantaneously, and as the freeze point of liquid nitrogen is negative 346 degrees, one can see that give Neptune's temperature, you would freeze solid before you could choke to death for lack of oxygen.
If you were very observant, you might notice in the second or two you'd have, that you were being buffeted by winds of around 1,200 miles per hour. I suppose this "wind chill" would make the negative 330 to 360 degrees feel colder, but I doubt you'd exist long enough to complain!
Assuming you were in a spacesuit, you'd still die. You'd have until you dropped through the atmosphere to the molten core comprised of rock, ammonia and methane. And as the gravity is 114% of Earths, drop you would. If you started at the top of the atmosphere, you would accelerate downward at approximately 36 feet per second per second, reaching a maximum velocity of approximately 137 miles per hour within 10 seconds.
As the atmosphere is about 4,350 miles deep, you'd have about 32 hours to be blown around before hitting that molten surface. Assuming you had 32 hours of air in your suit tanks, and assuming the winds and conditions didn't damage or destroy your suit.
There you have it. No suit, about 1 or 2 seconds. With a suit, possibly 32 hours, but probably not. The top of the atmosphere has unusually high temperatures of around 900 degrees, plummeting down to negative 373 degrees. This would have effects difficult for any of our standard protective suits to deal with, neverminding that there are bits of super heated debris blowing through the atmosphere at trans-sonic speeds!
Your best chance of survival is then to either not go there, or stay in the spaceship that took you there!
Is Neptune tenth closest planet to the sun?
No.
Currently there is no 10th planet.
Dwarf planets do not count.
Neptune is the 8th.
What did life used to be like on Neptune?
It is very doubtful that Neptune ever had any life. It is way too cold for life as we know it, -216 degrees Celsius at the cloud tops with varying temperature as you go down to the source. At the surface the pressure is immense. There is also a lack of oxygen and carbon dioxide, the two gasses needed for life on Earth, plus the presence of Methane, about 1%, which is poisonous. Any life that exists o has existed would have to be considerably different that life as found on Earth.
If a person weight 100 pounds on Earth how will he weight on Neptune?
You would weigh 119 pounds on Neptune if you were 100 pounds on Earth. However, Neptune is a gas planet consisting of a methane atmosphere so you can't actually stand on it.
Neptune is not rocky; it is a gas giant composed mainly of hydrogen and helium. It is very cold due to its distance from the Sun, with temperatures dropping to around -200 degrees Celsius.
Not really; Neptune has its axis (its poles) tilted at 28o which is very similar to the Earth's tilt of 23o.
Perhaps you are thinking of the planet Uranus which has its axis tilted 98o , which means that one of its poles is always pointed almost directly toward the Sun and the other pole is pointed toward the outer Solar System. This means that roughly one half of Uranus is always sunlit and the rest is always in darkness, which fits the word "sideways" pretty well.
Voyager 2 found new moons around what planet in 1989?
Voyager 2 found five new moons around Neptune in 1989.
- Naiad
- Thalassa
- Despina
- Larissa
- Proteus
How big does neptune look from earth?
Neptune appears as a small, bluish dot when viewed from Earth. Its angular size varies depending on its distance and position relative to Earth in its orbit around the sun. On average, Neptune's angular diameter is about 2.3 arcseconds when viewed from Earth.
Which planet takes longer to orbit the sun- Mars Or Neptune?
Neptune takes longer to orbit the sun than Mars. Neptune's orbital period is about 165 Earth years, while Mars' orbital period is about 1.88 Earth years.
What are the advantages of Neptune?
Some advantages of Neptune include its stunning blue color due to methane in its atmosphere, its 14 moons including the largest, Triton, and its dynamic weather patterns including the fastest winds in the solar system. Additionally, Neptune is the eighth and farthest planet from the Sun in our solar system.
Would a year on planet Neptune be longer or shorter than an earth year explain?
It would be longer because Neptune is farther away from the sun than Earth is. Then, Neptune revolution is 163.72 Earth YEARS and Earth revolution period is 365.26 Earth DAYS.
Hope I helped.
Which planet's name is green planet?
There are currently no planets discovered that are green in colour.
Earth has green on it, but the planet actually looks blue from space due to the large oceans.
What is the average orbital speed of Neptune in km-sec?
Neptune spins at a equatorial rate of 2.68 km/sec, or a velocity of 9,660 km/hr (6000 mph).
Large bundles of axons and dendrites visible to the unaided eye are?
Tracts of axons in the central nervous system (CNS) are visible to the unaided eye and are called white matter. In the peripheral nervous system (PNS), nerve bundles are visible and may appear as "cables" connecting different parts of the body.
If you weigh 87 pounds on earth then what would you weigh on planet Neptune?
You would not be able to actually stand on the surface because Neptune is a gas planet. But if you were in a structure that was able to fly (not orbit) on the "surface," you would weigh around 99.18 pounds.
What is the fastest wind speed on neptune?
The fastest wind speed on Neptune has been recorded to be around 1,300 miles per hour (2,100 kilometers per hour) in its upper atmosphere. These incredibly strong winds are driven by the intense heat generated deep within the planet.
What would happen if Neptune came closer to the sun?
If Neptune came closer to the Sun, it would experience higher temperatures, which could lead to the melting of its icy surface and loss of its atmosphere. The increased solar radiation might also cause significant changes in its weather patterns and overall climate.
How long does it take in earth years to orbit the sun?
It takes Earth approximately 1 year to orbit the sun.
How do you beat invading Neptune on n64?
I am assuming that you mean from Paper Boy, and the best way to beat it would be to search it in YouTube for a visual aid or to Google and type 'Paper Boy invading neptune walkthrough'

Are Neptune and Uranus brothers?
As planets, Neptune and Uranus are not considered siblings. However, in a mythological context, both planets are named after Roman gods, who were indeed brothers. Neptune is the Roman god of the sea, while Uranus is the Roman god of the sky.
How can humans travel to and from Neptune?
Humans cannot currently travel to Neptune as it is too far away and sending a crewed mission would be extremely challenging due to the long duration of the journey and the harsh conditions in space. Unmanned spacecraft, like the Voyager probes, have been sent to study Neptune and its moons.
