What is the distance between the earth and Neptune?
The distance between Earth and Neptune is between 29 and 31 AU, depending on their positions in the Solar System.
* ASTRONOMICAL UNIT (AU). 1 AU = 149,597,870.691 kilometers. * An Astronomical Unit is approximately the distance between the Earth and the Sun.
What is the meaning of Neptune's name?
Neptune (planet) is the eighth and outermost planet from the Sun in our Solar System. It is a giant planet and has a ring made up of particles of ice. It is the most remote of the giant gas planets. Its symbol is a stylish representation of the trident, which was the symbol associated with Neptune. Neptune (mythology) is the god of the sea, earthquakes and horses in Roman mythology after whom the planet is named; analogous to the god Poseidon in Greek mythology.
How far away is earth from neptune?
The Earth is about 2.7 billion miles from Neptune. This distance increases when the planets are on either side of the sun during their orbits.
What is the diameter of Neptune in kilometers?
4952800000 cm = 4.9528*109 cm
The diameter of Neptune, in kilometers, is 49528 km. (See http://www.kidzworld.com/article/1404-neptune-the-windy-planet )
100000 cm=1 km, so 49528 km=49528 km*100000 cm/km=49528*100000 cm=4952800000 cm = 4.9528*109 cm
What is Neptune's degree of axis?
The axial tilt of Neptune is 28.32 degrees. This is an average axial tilt, comparable to Earth, which is 23 degrees, and Mars, which is 25 degrees.
When was Neptune last visited?
As of 2011, only one spacecraft has passed relatively close to Neptune.
The Voyager 2 probe visited Neptune in 1989, having previously passed Jupiter, Saturn, and Uranus. Voyager 2 took the first close-up photos of the Neptunian moon Triton, and discovered five inner moons: Naiad, Thalassa, Despina, Galatea and Proteus.
What is the planet after Neptune?
Pluto used to be the ninth planet and the one farthest from the sun, but it was declassified as a planet due to lack of mass and gravity in August 2006 and so Neptune is now the planet farthest from the solar system.
Pluto was declassified as a planet because it lacked the new requirements for the classification of a planet introduced in 2006. Neptune, being four times the size of the Earth, is unlikely to be declassified any time soon.
Although there are no more planets after Neptune (unless you still count Pluto), there's still a whole bunch of stuff. There's a huge doughnut-shaped disc of comets, asteroids and other icy bodies stretching from just beyond Neptune's orbit out to about twice as far from the Sun, known as the Kuiper Belt (it was predicted in the 1950s by the Dutch-born American astronomer Gerard Kuiper, but it wasn't discovered until the 1990s.) There are thought to be over 70,000 Kuiper Belt objects (or KBOs) over 100km (60 miles) in diameter, and probably billions of smaller ones, but do far we've only discovered the thousand or so biggest/brightest/easiest to observe.
Although most of the thousands and thousands of known objects in the Kuiper Belt are tiny frozen comets or asteroids, a few dozen of the very biggest are massive enough to behave like small planets, with enough gravity to pull them into a rounded sphere, internal layers, atmospheres, surface features, etc. These KBOs are known as dwarf planets or plutoids and Pluto is now considered to be one of the largest plutoids/KBOs rather than a true planet. Three other plutoids are confirmed: Haumea, Makemake and Eris (which is more massive than Pluto.) A few dozen other KBOs may turn out to be plutoids too, once we've observed them more carefully and confirmed they are round like planets.
All the KBOs, whether they're comet nuclei, asteroids or plutoids/dwarf planets, are very, very cold. Most of them contain water ice, but it's so cold that that water is frozen as hard as steel, and it's so cold that other substances which are gases on Earth like methane, ammonia, carbon dioxide, carbon monoxide, and even nitrogen and oxygen (air itself!) are frozen solid. From the surface of a KBO, the Sun would be little more than a bright star.
What's beyond the Kuiper Belt? Astronomers don't know, but our observations of comets suggest many of them come from a huge, spherical shell of comets called the Oort Cloud. The distance from the Earth to the Sun is called an astronomical unit, or AU, and it's about 150 million km/93 million miles.
On this scale:
- Earth is 1AU from the Sun
- Neptune is 30AU from the Sun
- The Kuiper Belt stretches from 30-50AU from the Sun
- Some KBOs have orbits that take them out to 100AU from the Sun
- The Oort Cloud would be 30,000-100,000AU from the Sun!
The Oort Cloud seems to exist, based on our calculations, but it's so far away and the objects are so small and faint that nobody's ever seen it. Perhaps they never will. But the Oort Cloud, if it exists, extends out about a quarter of the way to the nearest star, marking the edge of the Solar System.
Does Neptune rotate horizontally?
No, Neptune axis of rotation, like that of Earth is basically at right angles to the plane of the ecliptic (the plane in which the planets rotate round the sun).
It is Uranus that has a unique configuration among the planets because its axis of rotation is tilted sideways, nearly into the plane the ecliptic, (i.e. its north and south poles lie where most other planets have their equators).
How much does neptune the planet weigh?
Neptune's mass is approximately 1.024×10^26 kilograms. Weight is a measure of the gravitational force acting on an object, so Neptune's weight would depend on the gravitational field where it is located.
What is the circumference of Neptune in miles?
Neptune's circumferece in miles is 96,683 miles and 155,596 kilometers
Is Blue Planet a nickname for Neptune?
No, "Blue Planet" is not a nickname for the planet Neptune.
Instead, the nickname perfectly describes planet Earth. Photographs taken of our planet from vehicles in space show Earth's predominant color to be blue. Each of the planets in our solar system photographs differently, and blue is the hallmark color of our planet.
How long does it take for Neptune to rotate?
Because Neptune is not a solid planet, the rotational speeds observed in its atmosphere vary greatly by latitude. The calculated rotational velocity is about 2.68 km/sec at the equator (about 9660 km/hr or 6000 mph), about 6 times as fast as on Earth.
Is there any water on the planet Neptune?
yes, the planet Neptune includes water in all the gases on the planet, like methane, ammonia, helium and hydrogen.
How long does it take to revolve around the sun for Neptune?
It takes Neptune about 164.8 Earth years to complete one orbit around the Sun.
What is Neptune's terraforming?
Terraforming a planet is the process of modifying it to make it like Terra (Earth) although it is normally used to simply refer to making the atmosphere breathable by higher animals and plants.
With this definition, Terraforming Neptune would be giving it an atmosphere that humans can breathe.
That being said, it's impossible to terraform Neptune, because it is a naturally stormy gas giant with winds raging up to 2,000mph, very little sunlight for food or energy, is too far from the sun to hold liquid water and has an exposed molten core that you'd fall into and be vaporised by if you try to stand on the planet.
Is Neptune a gas or terrestrial planet?
Neptune is a gas giant planet in our solar system, primarily composed of hydrogen and helium with some ices and rocky material. It is one of the four gas giants along with Jupiter, Saturn, and Uranus.
One of the spacecraft that has visited Mars is the Mars Curiosity Rover. Launched in 2011 by NASA, its main mission is to explore and assess the Martian climate and geology, and investigate whether Mars could have ever supported microbial life.
How long is one revolution of Neptune?
it takes Neptune 164.79 years to revolve around the sun.
There are two rotations for a planet, that of its own rotation, and that of its rotation round the sun. Equivalent to our Day and Year.
Is Neptune a gas or solid planet?
Neptune and Uranus are often called gas giants, but their composition may actually be closer to ice. They are sometimes called ice giants. but mostly neptune is none for being big and not warm like saturn, it is vary cold like uranus under 200 below thats alot compared to us its because its the farthest to the sun also like uranus but they are pretty big but the thing that people think is that it is big like saturn but it is closer to the sun so thats why neptune is a gas giant. :) also if you have a youtube account search pewdiepie and subscribe thanks :)
Also because the planet looks like it is full of water and Neptune is the god of the sea.
How long is a year on Neptune?
365 days 6 hrs 9 Min's 9.54 secs
Earth's year is 365 1/4 days
its takes 365.25 days earths year length is 366 days including leap year
Neptune was officially discovered by German astronomer Johann Gottfried Galle on September 23, 1846, based on calculations by French mathematician Urbain Le Verrier and English astronomer John Couch Adams.
How would a person fare on Neptune?
No, humans and life cannot survive on Neptune for the following reasons:
- Neptune is freezing. Life would freeze to death.
- Because Neptune is freezing, electronic equipment will also malfunction. Including space shuttles and space suits.
- Neptune is a stormy planet. Humans would be blown off into space.
- Neptune is a gas giant. Theoretically there is no solid surface to stand on, so you would sink into the planet and be consumed by the molten ammonia core.
- There is not enough sunlight to grow food or keep plants alive to process oxygen.
- There is no drinkable water, it would freeze instantly.
How long does it take neptune to rotate and revolve?
The rotation speed varies by location on the planet due to the gaseous atmosphere. However, the mean period (day) is about 16.11 Earth hours (16 hours, 6 minutes, 36 seconds).
Neptune's revolution around the Sun takes about 165 Earth Years (164.79 years).
About 16.1 hours and 165 Earth years, respectively, are.
