Planet Neptune

Pluto is, on average 3,607,000,000 miles from earth, which is 3699955887 miles from the sun. These are averages, not exact numbers as the planets shift in their orbits, especially Pluto's.

According to NASA's figures, the mass of Neptune is 102,440,000,000,000,000,000,000,000 kg or 102.4 quadrillion kg, or if you want the scientific notation 1.0244 x 1026 kg. This makes Neptune around 17 times the mass of the Earth.

Neptune was discovered using mathematics and predictions based on observed irregularities in the orbit of Uranus. French mathematician Urbain Le Verrier and English mathematician John Couch Adams independently calculated the position of Neptune in 1846. Once astronomers confirmed the existence of Neptune based on these predictions, the planet was officially discovered.

No, and he never will. Neptune is a gas giant. Which means it does not have a solid surface. If you tried to stand on Neptune, you would sink into the planet and be incinerated by the molten core.

That's, of course, if you don't get shredded to pieces by the 2,000+ MPH stormy winds, which contains rock, debris and ice.

Gas giants like Jupiter do not have a solid surface, so there is no clear boundary where the atmosphere ends and the surface begins. Instead, the gas giant's atmosphere becomes progressively denser as you move towards its core, gradually transitioning from gas to liquid under high pressures.

The dark spots on Neptune are large storms in its atmosphere, similar to hurricanes on Earth. These storms can be thousands of kilometers in size and are believed to be caused by complex interactions between different layers of the planet's atmosphere.

You would definitely weigh more, but the problem with the question is that we do not know the diameter of that part of Neptune that you can stand on.

When we talk about the measured diameters of the four giant planets, we mean the diameter measured across the tops of the clouds. It's assumed that there is a rocky core underneath but the size of it is unknown.

The usual answer given is about 112 pounds or 117 pounds, but it does indeed depend on the exact way the calculation is done.

Yes, but it has to be a pretty good telescope, and you have to know just where to look. Neptune will look like a fairly faint star, you wouldn't know it was a planet unless you waited for days and observed it moving.

i think you will not live until you reach the planet Neptune because you will be dead if you will reach. it imagine walking on a very long kilometer, you yourself do not want to walk in all at least just 2 kilometers. am i not right?

There are no inhabitants on Neptune. The planet is too gaseous, cold, and windy to support any sort of life.Also, there is very little amount of light and heat due to the long distance between the sun and Neptune.Due to this there can be no atmosphere or plant life.

No.

Neptune is a gas giant, it is composed entirely of gas.

Gas giants do not have any solid surfaces or plate activity. Therefore it is impossible for surface features such as mountains to form.

i had this in my homework, its Mars

The average distance between Neptune and its largest moon, Triton, is about 354,800 kilometers. Triton is the seventh-largest moon in the Solar System and is known for its retrograde orbit around Neptune.

164.79132 years. 163.7 Earth years. It is hard to be precise would be about 60,148 days, which is 164 years and about 9 and a half months.
Neptune takes 164.79 earth years to orbit once around our sun.

On all planets containing gas, there will be some movement in their atmosphere.

The atmosphere on Neptune some times moves at near supersonic speeds.

I should think this qualifies for being a most powerfull storm.

It is not true that the sun will not set for 2 days on the 17th of December. The length of daylight varies depending on the location and time of year, but the sun does set every day. This phenomenon might be a result of misinformation or a misunderstanding of how the sun moves across the sky.

"Uranus -224c,Neptune -218c,Saturn -175c,Jupiter -145c,Earth 7.2,Mars 30c,Venus 460c,Mercury 465c." This is actually incorrect. Mercury is not hotter than Venus. Yes Mercury is closer to the sun than Venus. However, Venus has a thicker atmosphere than Mercury.

There are a number of reasons that we couldn't live on Neptune. First, Neptune is what is called a gas giant (or ice giant, if you prefer). The tiny core of solid material is many miles deep in the atmosphere. The pressure there would crush us; it's millions of times that on the surface of the earth. Also, the atmosphere is primarily hydrogen, helium, methane, ammonia and water. That's not something we can breathe. Neptune is the "windiest" planet we know of with air movement of over 2000 kilometers per hour in some places. In the clouds, it's below -200 °C, and on the tiny rocky core, it's over 5,000 °C. Neither of those extremes is "comfortable" by any stretch. A link can be found below for more information.

The 'surface' acceleration of gravity on Neptune is 11.15 m/s2 .

That's about 14% greater than on the Earth's surface.

If you weigh 200 pounds on Earth, then at the depth in Neptune's gaseous mantle

where the pressure is equal to Earth's sea-level atmospheric pressure, you'd weigh

about 228 pounds.

The hottest planet is Venus. Then Mercury, Earth, Mars, Jupiter, Saturn, Neptune, Uranus, then if it was still a planet, Pluto.

(Uranus has been proven to be colder than Neptune, despite Neptune being further from the sun).
