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 old would you be on neptune if you were 12 years old?
Nice question! If you're one on Neptune, then you're 164.79 years old on Earth. We're researching stuff on planets at our school so just multiply 164.79 x 10. Sorry I didn't figure it out myself. Just lazy... :)
Why is neptune period is the longest revolution?
Answer
Neptune has the farthest average distance from the Sun of the 8 major planets. Not only is its orbit vastly longer, but it also moves more slowly in that orbit, because the reduced gravitational attraction of the Sun requires it to have comparatively less orbital momentum to counteract it. Neptune takes about 164.8 Earth years to make one orbit of the Sun.
What is the atmospheric content of Neptune?
Since Neptune's orbit is so far from the sun, it receives a very small amount of heat and indeed the uppermost region of the atmosphere is -218 °C (55 K). There is no solid surface due to the fact that Neptune is a gas giant. Atmospheric temperatures gradually rise as you go deeper inside Neptune due to an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, slowly radiating away into space right now. Neptune's atmosphere has the highest wind speeds in the solar system, up to 2000 km/h, thought to be powered by this flow of internal heat. The internal structure resembles that of Uranus.
Neptune consists of (molten) rock and metal, bounded by a blend of rock, water, ammonia, and methane. The atmosphere, extending perhaps 10 to 20 percent of the way towards the center, is typically hydrogen and helium at high altitudes, but has increasing concentrations of methane, ammonia, and water as it approaches and finally blends into the liquid interior.
The pressure at the center of Neptune is millions of times more than that on the surface of Earth. Comparing its rotational speed to its degree of oblateness represents that it has its mass less concentrated towards the center than does Uranus.
Neptune also resembles Uranus in its magnetosphere, with a magnetic field strongly tilted relative to its rotational axis at 47° and offset at least 0.55 radii (about 13,500 kilometres) from the planet's physical center. Comparing the magnetic fields of the two planets, scientists think the extreme orientation may be characteristic of flows in the interior of the planet and not the result of Uranus' sideways orientation.
One disparity between Neptune and Uranus is the level of meteorological activity. Uranus is visually quite bland, while Neptune's high winds come with distinguished weather phenomena. The Great Dark Spot, an Earth-sized dark marking similar to the Great Red Spot of Jupiter, disappeared in 1994 but another reappeared afterward. Distinctive among the gas giants is the presence of high clouds casting shadows on the opaque cloud deck below.
How does size of neptune compare to the size of the other gas giants?
neptune is the third bigest planet from the solar system
Why are neptune and Pluto so cold?

It is the furthest planet from the Sun
Mercury
Venus
Earth
Mars

Uranus
Neptune
Pluto
What was the Norse god name for neptune?
Neptune is the Roman god of the sea. He is also known as Poseidon by the greeks.
What is to the temperature difference between earth and Neptune?
Neptune's temperature is around 72 degrees Kelvin, which is about 200 degrees colder than the Earth.
Neptune is far further from the sun and as such is a much colder planet than earth.
Why does neptune have a lower surface temperature than mars?
Pluto is actually colder than Neptune at 33K. Neptune's surface temp drops to 72K and Uranus' drops to 76K. While Neptune should be much colder, it is thought to have a very high internal temperature.
Have you sent satellites or landers to neptune?
Not exactly. The Voyager 2 space probe did a flyby of Neptune, but since it never actually orbited the planet, it can't be considered a satellite. Neptune does not have a solid surface, so nothing could ever land on it.
How long does it take to rotate to Neptune axis?
Neptune takes 16 hours, 6 minutes and 36 seconds to rotate once on its axis. That's about 2/3rds of an Earth Day.
Note that the period of rotation is measured by watching Neptune's magnetic field. The time cited is the time it takes the "whole planet" to rotate once on its axis. This is important because Neptune is not solid - it's a big gas planet, and the atmosphere is rotating at different speeds.
What does the common term SM stand for?
----------------
S.M. Entertainment is a talent agency, producer, and publisher of K-pop, founded by Lee Soo-man in South Korea. Initially, "SM" was an abbreviation of the agency founder's name, but now stands for "Star Museum".
What affects distribution of Neptune's necklace?
Neptune's necklace (Hormosira banksii) is primarily influenced by environmental factors such as water temperature, salinity, and wave exposure. Its distribution is often found in intertidal zones and shallow coastal areas, where it thrives in conditions of moderate wave action. Additionally, nutrient availability and the presence of suitable substrates for attachment play significant roles in determining its habitat range. Climate change and oceanic conditions can also impact its distribution patterns over time.
One ligh year is equal to how many years on earth?
One light year is equivalent to about 5,878,400,000,000 miles on earth.
Would you have to wear a coat on neptune explain?
No. Neptune is cold enough that even a coat would not protect you.
Not at its surface, no. Neptune is mainly made from hydrogen and helium gas, though deep in it's core there will be large amounts of material which originally came from rocky asteroids and icy comets. So the dirt from these will be there, but the extreme pressures at these depths will have crushed any solid material into a super dense mixture.
