What do you know about Neptune? It is probably that it has become the last planet in the solar system, the eighth, after the agreement was reached that Pluto should be reclassified as one of the dwarf planets, but the characteristics of neptune They are many and interesting.
Neptuno
Among the characteristics of Neptune, we will find that it is the room of the Planets of the solar system in metric volume but the eighth in terms of distance from the sun. Its new positioning is very important, because today, all that celestial object that is beyond said planet, will be called trans-Neptunian object or trans-Neptunian celestial body.
The unveiling of Neptune was a huge success in astronomy for mathematics. It was the French astronomer Urbain Le Verrier who was able to calculate the existence and location of the new planet in 1846, all with the aim of being able to explain the aberrations observed in the orbit of the planet Uranus.
Later, Johann Gottfried was able to discover the planet we are referring to at 1º from that position, which could also have been calculated by the British-born mathematician John Couch Adams, but, unfortunately, British astronomers had the speed necessary at the time of making your discovery known.
Similarities to Uranus
According to the information about Neptune, we will say that it stood out for being almost a twin of the planet Uranus. This planet is 57 times larger than Earth. Now, it spins very fast, so much so that a day on Neptune lasts only 16 hours and 7 minutes, but a year on that planet lasts almost 165 Earth years. This meant that it was not until 2011 that Neptune completed its first orbit since it was discovered in 1846. Its average distance from the Sun is around 4.500 billion km.
As in Uranus, among the characteristics of Neptune is that it has an atmosphere made up of helium, methane and hydrogen. It is speculated that its core may be rocky and it seems that it has ice inside. Although it has a very cold atmosphere, this remote planet exhibits very strong winds and very strong storms. The Voyager 2 probe was able to capture an image in which a spot with the volume of the Earth could be seen, which was called the Great Dark Spot.
One of the characteristics of neptune is that it has temperatures that approach 260º below zero. It has clouds of frozen methane, which change very quickly. It is an immense ball of ice that is made up of a minimum of 5 dark and narrow rings, which have received the names of Galle, Le Verrier and Adams, and two other names of people who collaborated with the discovery of the planet.
It has 13 known moons, the largest of them, and by far the rest, is Triton. This is a kind of icy world, whose size is greater than Pluto. It is a very cold satellite, which is why its simple atmosphere is frozen on its surface.
Another planet with the most moons is Uranus, which has 27. Triton contains a large number of active ice volcanoes that are capable of spewing plumes of dust and gas. One of the peculiarities of Triton is that it moves in the opposite direction, that is, it moves from east to west, around Neptune. The cause of this may be that it was trapped due to the gravitational pull of this last planet for a long time. Of all Neptune's moons, only Triton is spherical and has a radius greater than 1000 kilometers.
Triton has a diameter of 2.710 kilometers and due to its size, it was the first satellite to be discovered, only 17 days after the planet was discovered. Due to its size, Triton is the seventh largest satellite in the solar system and it is most likely that it was previously a dwarf planet that ended up being captured in a Orbit that surrounds Neptune.
One of the facts on which this theory is based is that Triton is the only known moon that makes its orbital movement around its planet in the opposite direction to that in which the planet rotates.
Nereida is the second moon of Neptune that was discovered, in 1949. Later, in 1981, Larisa, which is the third moon, Larisa, could be discovered. Thanks to the activities of the Voyager 2 probe, which was able to fly over Neptune in 1989, it was possible to discover five more satellites. The rest of the satellites have been detected by means of telescopes from the Earth.
Characteristics of Neptune
The reason why Neptune is known as the planet that has the same color as the sea is not a mere coincidence. As with Uranus, the very bright bluish color is the product of the huge amount of methane in its atmosphere.
If we care to make a list of the first features of Neptune, we will find the following:
- Diameter: 49.572km
- Mass: 1,024 x 1026 kg
- Volume: 6,254×1013km3
- Density: 1,64kg/m3
In addition, between characteristics of neptune It is found that it is known to be a planet that possesses extraordinary winds. If you want to get strong winds in the Solar System, then you have to head to Neptune. Many of these winds blow in the opposite direction to their rotational movement and, around what has been called the Great Dark Spot, winds of 2.000km/h have been measured.
Neptune's magnetic field is tilted at 47 degrees and is about 13.500 kilometers away from its physical center. This kind of orientation may be due to outflows from its interior rather than the tilt of the planet itself.
Earlier we were able to tell you about the density of Neptune. However, the densest planet in the solar system is ours. For that reason, Earth is at the top of the list of dense planets.
Curiosities of the planet Neptune
That other ice giant is full of mysteries that we want to discuss in this post for you, so we invite you to travel with us to the universe. One of them is that it is speculated that the raindrops on Neptune are giant in size, which can be the size of soccer balls.
One of the characteristics of Neptune is that this can be caused because the atmosphere of this planet contains twenty times more methane than those of Jupiter and Saturn. Another speculation is that the interior of Neptune is made of diamonds. Neptune's atmosphere is shrouded in mystery, of course, but the truth is that its inner part is even more so.
There is a presumption that under the atmosphere of hydrogen and helium, a liquid bed can be found that is composed of these elements and various ices, and below it follows a core composed of ice and rock. Although it is not possible to say absolutely, Neptune's mantle could be full of giant diamonds.
Although one of the characteristics of Neptune is that it is much further from the Sun than Uranus and is only capable of receiving 5% of the solar energy that the planet Jupiter can capture, the surface of this planet, whose color is itself from the sea, manages to reach about the same temperature as that of Uranus.
The greatest mystery is that its atmosphere has not stopped warming in the last twenty years, although in that period the planet was far from the Sun in its orbit. Mercury is a hot planet, whose temperature never drops below 400º, but it is not the hottest either.
The great distance at which Neptune is located, although it is a giant planet, it cannot be seen with the naked eye from Earth. That may be the reason why this planet would not have been known by ancient civilizations. It can be said that its unveiling was an effect of the discovery of Uranus.
Some additional facts about Uranus
When astronomers managed to discover the planet Uranus, they observed that its orbit had a movement that was not predictable. That was what allowed them to guess that there could be a large celestial body, located at a relatively close distance from Uranus, which managed to affect its orbit due to gravity.
The planet Uranus was discovered by the astronomer William Herschel in the year 1781. This discovery caused great commotion among scientists and highlighted the restricted understanding of our solar system at that time.
Astronomers immediately began to observe this new planet and to carry out all kinds of measurements with the appropriate paradigms to be able to describe its orbit. After about 60 years, at which time Uranus managed to complete its first orbit since its discovery, scientists were able to verify that it did not seem to follow the rules of orbital mechanics exactly and that small deviations were found in its orbit that had no explanation.
All kinds of hypotheses tried to explain these discrepancies between theory and observation. In the year 1845, more or less simultaneously but without contact between them, the astronomers Urbain Le Verrier and John Couch Adams began to explore the hypothesis that these deviations had their origin in the existence of another planet located near Uranus. .
Apparently, both scientists were able to calculate what the approximate position of this new planet should be, but it was only thanks to the calculations made by Urbain Le Verrier that the astronomer Johann Gottfried Galle was able to observe Neptune for the first time from the Neptune Observatory. of Berlin.
The discovery of Neptune could be confirmed in the year 1846 and then some controversy arose as to who should be considered its discoverer. The Royal Society of London gave Urbain Le Verrier a medal of honor for the discovery, although many astronomers also sponsored John Couch Adams' contribution.
Thus, based on the eccentricities that could be observed in the orbit of Uranus, the existence and location of an eighth planet could be deduced. When they looked through the telescope to the place that, according to mathematics, had been speculated that another planet might be found, they were indeed able to find Neptune.
Neptune's name
The planet Neptune was named after the god of the waters and seas of Roman mythology, because its blue color is similar to the color of the seas. At first, the planet was known by the name of Le Verrier, who was its discoverer, but later the name Neptune was the one that had more acceptance, since it followed the tradition of giving the planets the names of the gods of Roman mythology. .
Going back to characteristics of Neptune, We will say that it is the smallest of the four gas giants that exist in our solar system, which are Jupiter, Saturn, Uranus and Neptune. However, it has a great density makes the gravity that its surface has one of the most robust of the planets of the solar system, which is second only to gravity on Jupiter.
Neptune, which has an average diameter of 49.528 kilometers, is slightly smaller than Uranus, which has a diameter of 51,118 kilometers. These two planets are considered icy giants, due to their composition, which essentially includes ice made up of different substances.
size of neptune
Although it is also known as the gas giant, the name ice giant is the one that should be applied to differentiate it from the two main gas giants found between the ice giants. Curiosities of the Solar System, which are Jupiter and Saturn. The explanation is that Jupiter and Saturn are essentially 90% hydrogen and helium, but Uranus and Neptune are only 20% hydrogen and helium. It is this difference that justifies making the distinction between gas giants and ice giants.
As the gas giants do, Neptune rotates very quickly on its own axis, completing a full revolution in 16 hours, as we have already indicated. Due to the gaseous nature of its outermost layers, Neptune does not have the same speed of rotation at different latitudes. In fact, its areas of the equator can take up to 18 hours to complete a complete revolution.
In addition, its axis of rotation is slightly tilted, as is the case with the Earth. In the case of Earth we know that the angle of inclination is 23.5° and in Neptune it is 28.3°. This inclination is what causes the seasons of the year, because it makes the sun's rays arrive with different orientations, depending on the time of year.
It is true that there is a great distance between the Sun and Neptune, which is why the Sun's rays that manage to reach Neptune are very weak. But, despite this, seasonal changes can be observed in its atmosphere. But, since Neptune takes 165 years to go around the Sun, the seasons on Neptune last much longer than on Earth. In fact, each season can last about 40 years.
one of the characteristics of neptune What is little known is that it has a ring system, much weaker, yes, than the known rings of Saturn. At least 5 rings of Neptune are known, each of them with an amplitude that varies between 100 and 1000 kilometers.
