Neptune's ring system is composed of five main rings named Galle, LeVerrier, Lassell, Arago, and Adams, but they are faint and difficult to see. These rings are made up of mostly dust particles and are thought to be made up of remnants from comets or asteroids. The rings were first discovered in 1984 by the Voyager 2 spacecraft.
What is Neptunes precipitation?
Neptune experiences extremely high wind speeds and storms with powerful jets of wind exceeding 1,500 miles per hour. Although it is likely that precipitation occurs in the form of rain or possibly even diamonds, its exact composition and distribution remain unknown due to Neptune's distance and the limited data available from spacecraft flybys.
What is the length of Saturn's daily rotation?
The Overall Rotation of the Planet
Since Saturn does not have a solid surface, it is difficult to define a rotation period for the planet as a whole. Different portions of its visible "surface", which represent different circulation systems in its atmosphere, move around its axis at different rates, according to whether they have westward or eastward motions relative to the overall rotation of the planet. "System I", which refers to the Equatorial region, has a rotation rate of around 10 hours 14 minutes, while "System II", which refers to non-Equatorial regions, has a rotation rate of around 10 hours 39 minutes. There is also a "System III" rotation, which refers to the rate of rotation of the planet's radio emissions, which was once thought to refer to the rotation of the "body" of the planet, and at the time of the Voyager flybys, was around 10 hours 39 minutes. However, in the years since then, the System III rotation period has increased to 10 hours 45 minutes, indicating that it is not associated with the "real" rotation of the planet. Alterations in the position of the radio field, and in the plasma field surrounding the planet (possibly caused by geyser eruptions on Enceladus), are thought to be responsible for the change in the System III rotation rate; but whatever the cause of these changes, they cannot be due to a change in the rotation of the body of the planet. So the once-hoped-for fundamental nature of the System III rotation period has been disproved, and there is no currently conceivable way of estimating the "real" rotation of the planet as a whole. A recent compilation of results yields a rotation period of 10 hours 32 minutes 35 seconds; but this value is like the proverbial two point something children per American family -- it may be mathematically useful, but it cannot be representative of any real family, since no family can contain a fraction of a child. In the same way, the compiled rotation period may be useful for some calculations (e.g., the comparison of roation period and day length mentioned below), but it has no correspondence to any real part of Saturn.
Regardless of these uncertainties, there is no doubt that Saturn has the second-fastest rotation rate of any planet, both in terms of its rotation period, and the speed of its rotation at the Equator, which is just under 10 kilometers per second, or about 35000 kilometers per hour (or just under 6 miles per second, or about 22000 miles per hour). Only Jupiter has a faster rotational velocity or rotation period.
Difference Between Rotation Period and Day Length
Since the rotation period of Saturn is so uncertain, the difference between its rotation period and day length is, for all practical purposes, unimportant; but as discussed at Rotation Period and Day Length, given its rapid rotation and long orbital period, the difference between the two values is only about one second. So no matter where you are on Saturn, whatever the local rotation period is, the length of the day is one second longer.
The Rotational Tilt of Saturn
The axis of Saturn's rotation is tilted relative to its orbit by just under 27 degrees. This means that insofar as Saturn has seasons, they would be similar to those on the Earth, being relatively minor at the Equator, relatively extreme at the Poles, and in-between at in-between latitudes. However, since Saturn's temperature is over 200 degrees below zero Fahrenheit, even its warmest summers are very cold by Earthly standards, and seasons as we know them do not exist.
Despite the lack of obvious seasonal effects, the tilt of Saturn's axis does produce a very easily observable effect, because the ring system of the planet and the orbits of virtually all of the planet's moons are very closely aligned to the planet's Equatorial plane. Therefore, as discussed at The Rings of Saturn, when we see Saturn near one of its polar summers, we see the rings from above or below, as a broad, spectacular oval; whereas when we see Saturn near the start of its spring or fall (as we do in 2008 and 2009), the rings are barely visible, due to our nearly edge-on view
Defining the age of a moon is very difficult, especially Triton.
Because Triton is more than likely, a captured KBO (Kyper belt object) it can be said to be part of the original formation of the Solar System at about 4.6 billion years old.
However, it's surface is relatively young - in astronomical terms - with regions varying from 50 million years old to just 6 million years old.
I think a lot depends on "what" part of Triton!
Why does Jupiter orbit faster than Neptune?
The simplest and most accurate answer to the question is: Because that's how
gravity works.
The way gravity works, an object in a smaller orbit always moves faster than an
object in a larger orbit around the same central body. "Faster" in this context means miles per hour or other, similar measures of velocity (linera distance per unit time).
So the object in the larger orbit takes a double hit: It has farther to go, PLUS
it moves slower, so it's definitely going to take a lot more time for each orbit.
Here's a real-world, everyday example that's right in front our face and so
obvious that we don't even notice it:
-- International Space Station, about 240 miles up, takes 91 minutes per orbit.
-- That's about 570 miles per minute.
-- Geostationary TV satellite, about 22,000 miles up, takes 24 hours per orbit.
-- That's about 113 miles per minute.
-- Moon, about 240,000 miles up, takes 27.32 days per orbit.
-- That's about 39 miles per minute !
And also by the way, none of this has anything to do with the size or the
mass of the orbiting body. Makes no difference. Only the size of the orbit.
That's why an astronaut on a 'space-walk' was able to float gently away from
the Space Shuttle, and then float gently back to it. While they were separated,
the Shuttle and the astronaut moved at the same speed and stayed in the same
Earth orbit, even though the Shuttle was somewhat larger and had a little more
This phenomenon is called "Kepler's Law of Periods". Look that phrase up to find out more about it.
Most people would say no But I heard from a reliable source there is large population of underground alliens. They are similar to a cult they like mad beats and follow a leader that goes by the name Dollabill
Why are there no giant planets beyond Neptune?
well probably because when the solar system formed, the sunwas made of gas and dust, the remaining gas and dust not used on the sun became the planets, most likely during the formation of the planets their was only enough dust to make 9 planets and a few million asteroids
Neptune's Distance from the earth?
Neptune's average distance from Earth is about 2.7 billion miles (4.3 billion kilometers) when the two planets are at their closest approach. However, this distance can vary as both planets follow their elliptical orbits around the Sun.
How strong are the winds on Neptune?
The winds on Neptune can reach speeds of up to 1,300 miles per hour (2,100 kilometers per hour), making them the strongest in the solar system. These high-velocity winds are due to Neptune's fast rotation and its turbulent atmosphere.
Neptune is one of the gas giants that orbit in the outer solar system. It is spherical, like the other planets. Gravity has pulled together all the material that composes this odd planet, and it is gravity that determines its shape. One determinate of whether or not a body is a planet is whether or not gravity has rounded its structure.
What is the name of the mythical Weeper?
The mythical Weeper is known as the "Banshee." It is a female spirit in Irish folklore believed to forewarn of death by wailing or keening.
How many diameters on neptune equals on kilometre?
Neptune has a diameter of about 49,244 kilometers. So, approximately 49,244 diameters of Neptune would equal one kilometer.
Where did planet Neptune gets its name from?
Planet Neptune got its name from the Roman God of the deep sea, Neptune.
The name also fits the planet because of its ocean-like appearance and because it's in deep space (deep sea-deep space).
What are Neptunes physical features?
Neptune is a gas giant with a mostly hydrogen and helium atmosphere. It has a blue color due to the presence of methane gas in its atmosphere. Neptune also has a system of rings and 14 known moons.
No, humans could not live on Neptune. Neptune's extreme cold temperatures, high wind speeds, and lack of a solid surface make it inhospitable to humans. Additionally, the planet's atmosphere is mainly composed of hydrogen and helium, which are not breathable for humans.
Composition of Neptune and its Appearance?
Neptune is mainly composed of hydrogen, helium, and water ice, with traces of methane and ammonia. It has a blue color due to the absorption of red light by methane in its atmosphere. The planet has a dynamic atmosphere with high-speed winds and visible cloud patterns.
No, Neptune is not a star. It is the eighth and farthest known planet from the Sun in our solar system. It is a gas giant like Jupiter and Saturn, not a star which generates its own light through nuclear fusion.
Sidereal rotation period is approximately one Neptunian day, time taken to rotate once on its axis. This is 0.67 days or 16h 6min 36sec.
What is Neptune the planet's core made of?
The mantle of Neptune is rich in water, ammonia, and methane. As is customary in planetary science, this mixture is referred to as icy even though it is a hot, highly dense fluid. This fluid, which has a high electrical conductivity, is sometimes called a water-ammonia ocean. At a depth of 7,000 kilometres (4,300 mi), the conditions may be such that methane decomposes into diamond crystals that then precipitate toward the core. The Core of Neptune is composed of iron, nickel and silicates, with an interior model giving a mass about 1.2 times that of the Earth. The pressure at the centre is 7 Mbar (700 GPa), millions of times more than that on the surface of the Earth, and the temperature may be 5,400 K.
So basically, the pressure is so great at its mantle, it crushes methane into solid diamond, and the diamond sinks to the core. It's estimated that it has a solid diamond core larger than Earth.
Why was the discovery of Neptune a major confirmation of Newton's law of gravitaion?
There were anomalies in Uranus' orbit that astronomers thought could be evidence of another planet pulling it out of orbit. This theory was later confirmed. It supports the law of gravitation because of Neptune's exertion of a force on Uranus that caused it to have a different orbit than predicted.
Answer
The density of Neptune is 1.638 kg/m3.
Answer
Neptune's density is 1.638 g/cm³. That means that in every cm cubed it weighs 1.638 grams.
Answer
Neptune's average, or mean, density is 1640 kg/m3.
What colour are Neptune's rings?
Neptune's rings range from white to very light blue. They would be almost invisible to the naked eye without assistance from a telescope because they are not very thick and have an almost misty-like appearance.
