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.

September 23, 1846. It was discovered by mathematical prediction by Johann Galle, meaning that's it's whereabouts was predicted through gravitational effects of other planets.
Is the moon bigger than Neptune?
Yes, specifically the four largest, or Galilean satellites : Ganymede, Callisto, Io, and Europa. At 3100 to 5200 km in diameter, they are larger than Pluto's 2306 km diameter, and are correspondingly greater in mass.
The large moon of Saturn, Titan, is also larger than Pluto. In fact, Ganymede and Titan are larger than the planet Mercury, but not as massive.
How far is Pluto from Neptune in miles?
This distance varies every day as Saturn and Pluto take up different positions in their respective orbits.
What are some unique things about Neptune?
Neptune is far from the sun so it receives hardly any heat; the atmosphere is actually -218 C. There is no solid surface and Neptune's atmosphere is known to have the highest speed when it comes to the wind.
The first planets discovered since ancient times were Uranus and Neptune How were they discovered?
Jupiter and Saturn are visible to the naked eye and have thus been know since ancient times (thus nobody knows who first discovered them).
Although Uranus is visible to the naked eye, it was never recognized as a planet by ancient observers because of its dimness and slow orbit. Sir William Herschel announced its discovery on March 13, 1781.
Neptune was the first planet found by mathematical prediction rather than by observation. Unexpected changes in the orbit of Uranus led Alexis Bouvard to deduce that its orbit was subject to gravitational perturbation by an unknown planet. Neptune was subsequently observed on September 23, 1846 by Johann Galle within a degree of the position predicted by Urbain Le Verrier.
A human would die almost instantly.
For the following reasons:
- Neptune is freezing cold. Life would freeze to death. Electronic equipment would malfunction
- Neptune is very stormy. Life would be ripped apart by the high winds or even catapulted into space
- There is no breathable atmosphere. The atmosphere is very poisonous
- There is very little light. No light equals no plants, food or power
- Neptune is a gas giant, which means it does not have a surface. Anyone who tries to stand on Neptune will just sink into it and be incinerated by the molten core
Yes, Neptune is a proper noun because it is the name of a specific planet in our solar system.
What is Neptune surface feature?
Neptune doesn't have a surface because it is a gas giant. It is composed of hydrogen, helium and methane gases with a core of molten rock and molten ammonia.
Neptune is very stormy. In fact, it has the fastest wind speeds discovered so far. Occasionally you can see black spots appear and disappear in Neptune's atmosphere. These are anticyclone storms.
No.
There is no water on Neptune.
Neptune is a gas giant, which means it is made of gasses and has no solid surface. With no surface it is impossible for water to form.
The blue is caused by methane gasses in Neptune's atmosphere reflecting back the blue light spectrum from the dim sunlight that reaches the planet, giving the appearance through our telescopes that Neptune is blue.
But whether Neptune really is blue or whether it's entirely an illusion caused by light reflections is an open debate.
Why was Neptune named after a greek god?
It was named after the Roman God of the deep sea, Neptune, to keep up the tradition of naming planets after mythical figures.
The name also fits because the planet appears to be blue and it is in deep space (deep sea-deep space).
What is the capital of Neptune?
Neptune is an uninhabited planet.
No people, no need for cities, thus...no capital.
What unusual features or landforms does Neptune have?
Neptune has the fastest winds in the solar system, reaching speeds of up to 1,300 mph. It also has the Great Dark Spot, a storm system similar to Jupiter's Great Red Spot. Another unusual feature is Triton, Neptune's largest moon, which orbits in the opposite direction of Neptune's rotation.
Is neptune the fifth planet from the sun?
yes it is the fourth planet of corse trust me im dum but i know this!! :)
Has there been travel to Neptune?
No. The best information about the planet comes from the probe Voyager 2, which passed near Neptune in August 1989. It has been studied telescopically from Earth orbit by the Hubble Telescope and from Earth observatories using adaptive optics technology.
Neptune is often referred to as the "Blue Planet" due to the blue hue of its atmosphere. Another nickname is the "Ice Giant" because it is composed of icy materials like water, ammonia, and methane.
Is there anything special about Neptune's moons?
Neptune has 13 known moons. The largest by far, comprising more than 99.5 percent of the mass in orbit around Neptune and the only one massive enough to be spheroidal, is Triton, discovered by William Lassell just 17 days after the discovery of Neptune itself. Unlike all other large planetary moons in the Solar System, Triton has a retrograde orbit, indicating that it was captured rather than forming in place; it probably was once a dwarf planet in the Kuiper belt. It is close enough to Neptune to be locked into a synchronous rotation, and it is slowly spiraling inward because of tidal acceleration and eventually will be torn apart, in about 3.6 billion years, when it reaches the Roche limit. In 1989, Triton was the coldest object that had yet been measured in the solar system, with estimated temperatures of −235 °C (38 K).
Neptune's second known satellite (by order of discovery), the irregular moon Nereid, has one of the most eccentric orbits of any satellite in the solar system. The eccentricity of 0.7512 gives it an apoapsis that is seven times its periapsis distance from Neptune.
From July to September 1989, Voyager 2 discovered six new Neptunian moons. Of these, the irregularly shaped Proteus is notable for being as large as a body of its density can be without being pulled into a spherical shape by its own gravity. Although the second-most-massive Neptunian moon, it is only one-quarter of one percent the mass of Triton. Neptune's innermost four moons-Naiad, thalassa, Despina and Galatea-orbit close enough to be within Neptune's rings. The next-farthest out, Larissa was originally discovered in 1981 when it had occulted a star. This occultation had been attributed to ring arcs, but when Voyager 2 observed Neptune in 1989, it was found to have been caused by the moon. Five new irregular moons discovered between 2002 and 2003 were announced in 2004. As Neptune was the Roman god of the sea, the planet's moons have been named after lesser sea gods.

What are the names of Neptune's seas?
The names of Neptune's seas, or large dark spots, are:
- The Great Dark Spot
- The Dark Spot
- The Scooter
- The Small Dark Spot
Neptune is a gas giant without a solid surface. It is made up mostly of hydrogen and helium, along with traces of methane and other gases. The outer atmosphere is composed of thick clouds that obscure any solid surface that may exist deep within the planet.
Where does the earth receive direct sunlight?
The Earth receives direct sunlight at the equator, where rays of the sun strike the surface at a perpendicular angle due to the Earth's tilt. This results in more intense and direct sunlight at these regions, leading to warmer temperatures.
What is the length of a Neptune day and year?
- A year on Neptune is 164.79 Earth days
- A day on Neptune is 16 h 6 min 36 s
How high could you jump on Neptune?
Due to its strong gravitational pull, you would be able to jump much higher on Neptune compared to Earth. However, the exact height would depend on various factors such as your weight and leg strength. Generally, you could potentially jump several times higher than on Earth.
What are Earth's and Neptune's rates of rotation?
One revolution in 23 hours 56 minutes, or 3.988888 degrees per minute.
No
but sintist have found water on the bottom of the moon. and you know what they say: ware theirs water theirs life. not always intelligent life but life
Astronomers saw some deviations from the expect orbit of the planet Uranus. Based on these deviations, some theorized that Uranus was being pulled out of its expect orbit by another planet, which turned out be Neptune.
If the left aileron on a plane is down and the right one is up what way does the plane rotate?
The plane rotates (banks) right. The force of the aileron on the left down will result in the left wing moving up. With the right aileron moving up, the right wing will move down. The result is a right banking move.
