Planet Neptune

Neptune is 30.069 miles away from the sun Earth 9 million

No.

The 7th is Uranus. Neptune is the 8th.

No, Venus is not colder than Neptune. Venus has higher surface temperatures due to its thick atmosphere, greenhouse effect, and proximity to the sun, while Neptune is much colder as it's located much further from the sun in the outer solar system.

Neptune is actually the farthest planet from the Sun in our solar system. Being so far from the Sun causes Neptune to have extremely cold temperatures and a very long orbital period of about 165 Earth years. Its distance also affects the amount of sunlight and heat it receives, making it significantly colder than the inner planets like Earth.

Both Jupiter's Great Red Spot and Neptune's Great Dark Spot are large, persistent storm systems in their respective atmospheres. They are both visible features on the planets that have been observed by telescopes and spacecraft. Additionally, both features are dynamic, changing in size, shape, and intensity over time.

Not yet.

And there never will be a spacecraft landing on Neptune.

The reason being, because Neptune is a gas giant, it has no solid surface for a spacecraft to land on.

Neptune is also freezing cold. Electronic equipment such as a spacecraft would freeze up and malfunction in its atmosphere and most likely end up being consumed by the exposed molten ammonia core.

Neptune's surface is not solid, so it doesn't have a rough or smooth texture like a planet with a solid surface would. The planet is mostly composed of gas and ice, with turbulent weather systems creating ever-changing cloud patterns.

To date, only one probe has made a pass at Neptune. Voyager 2 in August 1989.

Future passes and probes have been planned or are currently still making the journey across the solar system.

Neptune is a gas giant with no solid surface, so it does not have any plains like we find on rocky planets such as Earth or Mars. The planet's upper atmosphere is composed of hydrogen, helium, and methane gases, with no solid landforms visible.

Running on Neptune would be impossible as it is a gas giant with extreme wind speeds reaching up to 1,300 miles per hour. Additionally, the planet's gravity is 14% stronger than Earth's, making movement very difficult for humans.

Neptune is much farther from the Sun than Earth, so it receives much less sunlight and heat. Additionally, Neptune's atmosphere contains methane, which acts as a greenhouse gas, trapping heat and contributing to its colder average temperature compared to Earth.

Naiad, Thalassa, Despina, Galatea, Larissa, Proteus, Triton, Nereid, Halimede, Sao, Laomedeia, Psamathe, Neso.

Naiad, Thalassa, Despina, Galatea, and Proteus were found in 1989 by Voyager 2. The last 5 moons were found in 2002 and 2003 by ground-based telescopes.

The space probe "Voyager 2" flew past Neptune.

It would take about 9 years for a spacecraft to reach Uranus using current technology, such as the Voyager or New Horizons spacecraft. However, there are no current plans for a mission to Uranus, so it may be longer before another spacecraft is sent to explore the planet.

Neptune's color is a vibrant azure blue, with hints of green and blue due to the presence of methane in its atmosphere. The planet's distinctive hue comes from the way methane absorbs red light, leaving mostly blue and green wavelengths to be reflected back into space.

Neptune's atmosphere is made up of hydrogen, helium and methane. The methane in Neptune's upper atmosphere absorbs the red light from the sun but reflects the blue light from the sun back into space. This is why Neptune appears blue.

Neptune has a shorter day than Earth, it spins once on its axis in 16 hours and 6 minutes, compared to 24 hours for Earth.

The atmosphere of Neptune is primarily composed of hydrogen, helium, and methane. The presence of methane in the atmosphere gives Neptune its blue color. The air quality of Neptune would not be breathable for humans due to the lack of oxygen and high concentrations of methane.

Neptunes days are 16 hours, 6 minutes and 36 seconds in averate.Being a gas giant Neptune isn't solid so the closer one gets to the poles the faster the spin about 12 hrs or slower at it's equator about 18 hrs with eddies and whirlpools in between.

try watching a river at its bend and drop a bit of wood as a reference----not all of the water moves at the same speed

Neptune is the eighth planet from the sun and the fourth largest by diameter in our solar system. It is an icy giant planet with a thick atmosphere composed mostly of hydrogen, helium, and methane. Neptune is known for its vivid blue color and its strong winds, making it one of the windiest planets in our solar system.

The Voyager 2 spacecraft is the only man-made object to have visited Neptune. It flew by Neptune in 1989, capturing close-up images and data about the planet and its moons. No other satellites or robots have been sent close to Neptune since then.

Neptune is located beyond the asteroid belt as are all the gas giants. In fact, as of Pluto's demotion, Neptune is the farthest planet from the sun.

The only spacecraft to pass by both Uranus and Neptune was Voyager 2. It was launched by NASA in 1977 and conducted flybys of several planets in our solar system before reaching Uranus in 1986 and Neptune in 1989. Voyager 2 provided valuable data and images of these two gas giants.
