Planet Neptune

At the present time (2011), there is no program underway to develop a manned

mission to Neptune, there is no research being done to advance the technology

that it would require, there is no planning being done for such a mission, there

is no funding for any research or planning with that purpose, there is no money

in the US space program's budget for any activity aimed toward planning or

developing such a mission, and at the moment, the US no longer has any ability

to launch people into space.

So at the present rate, it's liable to be a while.

Neptune's ground is thought to be composed of a mixture of water, ammonia, and methane ices, along with silicate rock. The extreme pressure and temperatures on Neptune prevent these materials from existing as solid, liquid, or gas in the same way we experience them on Earth.

Neptune does have a solid surface beneath its thick, thick atmosphere. You would fall through the visible surface (then fall 20% of the planets diameter) but would probably be able to stand on the solid surface beneath. ( Note, we do not know for sure because no direct measurements have been taken).

It takes 164.8 years to complete one revolution to neptune around the sun

Neptune is about 4.503 x 109 km from the sun. (Semi-major axis)

A month on Earth is based on the amount of time it takes for the moon to make an orbit. Uranus has at least 27 moons, each with a different orbit time, so a month on Uranus doesn't make much sense.

No, humans have not been to Neptune and there are no known pie vendors on the planet. Additionally, the extreme conditions on Neptune would make it impossible for humans to survive without special equipment.

Neptune is officially the furthest known planet from Earth in our solar system.

Pluto was previously the furthest, but it is no longer classified as a planet.

The Lexile measure for "Son of Neptune" by Rick Riordan is 590L.

There is no evidence to suggest that Neptune has ever been inhabited by any form of life. Neptune's harsh environment, including extreme cold temperatures, high winds, and lack of solid surface, make it inhospitable for life as we know it.

No, vegetation does not grow on Neptune because it is a gas giant planet with no solid surface for plants to take root in. The extreme temperatures, lack of sunlight, and high levels of methane in the atmosphere make it impossible for any kind of plant life to survive there.

The planet Neptune is the coldest in our solar system, with temperatures dropping to about -370°F (-224°C). Its distance from the Sun, its faint amount of sunlight received, and its composition largely consisting of ice and rock contribute to its extreme cold temperatures.

Neptune is the eighth and farthest known planet from the Sun in our solar system, while Mercury is the closest planet to the Sun. Neptune is a gas giant, primarily composed of hydrogen, helium, and methane, whereas Mercury is a rocky planet with a thin atmosphere. Neptune has a much longer orbital period, taking about 165 years to complete one orbit, while Mercury orbits the Sun much more quickly, completing an orbit in about 88 days.

Walking on Neptune would be impossible due to its gaseous composition and extreme weather conditions. Neptune's atmosphere is mostly hydrogen and helium with traces of other gases, and its surface experiences speeds of up to 1,300 miles per hour and temperatures of minus 360 degrees Fahrenheit. So, walking on Neptune is not something that is achievable.

Mars' average distance from the sun is about 1.52 astronomical units (AU), which is approximately 227.9 million kilometers.

equation for time in pendulum:

t = 2 * pi * ( sq. root (l / g))

key:

t = time elapsed ( total, back and forth )

l = length , from pivot to centre of gravity

g = acceleration due to gravity

say 1 metre length pendulum on earth @ 9.82 (m/s)/s, t = 2.005 seconds

same pendulum on neptune @ 11.23 (m/s)/s, t = 1.875 seconds

The outer planets do not receive any energy from the sun because there really far away.

The gas giants don't have a surface, or the pressure at the core (probably liquid) would be unbearable. The outer planets that do have a solid surface are too far away from the Sun to be habitable. We would have to overcome the freezing temperature and deal with the gravity difference. One of the outer planets' moons would be more probable.

They are considered the same deity under different names.

Yes, Neptune is a blue planet due to the presence of methane in its atmosphere that absorbs red light, reflecting blue light. Neptune also experiences some of the highest recorded wind speeds in our solar system, reaching up to 1,500 mph (2,400 km/h).

The hurricane on Neptune, known as the Great Dark Spot, is about the size of Earth. It is a massive storm system that can span over 13,000 kilometers in diameter.

Yes, Neptune does have seasons. However, the seasons on Neptune are different from Earth as they are caused by its tilted axis and extremely long orbital period. One year on Neptune is equivalent to about 165 Earth years.

pluto's orbital period is 247.7 years, very close to one and one -half times Neptune's .thus pluto makes two orbit's around the sun for every three made by Neptune.This match of orbital period may have created a cumulative gravitational attraction on Pluto that "tugged" it into it's orbit.

There are two regions in the solar system past Neptune, both of which contain icy planetoids. The inner area is called the "Kuiper Belt", and includes objects which are in relatively stable orbits around the Sun. Farther out, the "scattered disc" region is thought to be the origin of periodic comets, bodies which have been disturbed by Neptune's gravity and enter the inner solar system.

No. Neptune has a diameter of about 49,000 KM, while Titan has a diameter of about 5150 KM.
