Neptune is a very peculiar planet due to its characteristics. One of the Curiosities of Neptune its composition makes it one of the most anomalous stars, and being so separated there are very few studies on it. Therefore, today we are going to show you some extraordinary facts about Neptune that you should know.
8 Curiosities of Neptune
Some of the curiosities of Neptune, are:
1. Neptune is the furthest planet from the Sun
In 1846, Neptune was enlightened and it was learned that it was the satellite farthest from the Sun. However, Pluto was discovered in 1930, making it the farthest planet. The problem is that at times Pluto's spiral orbit brings it closer to the Sun; the last time it passed was from 1979 to 1999. If you'd like to learn more about this interesting planet, we invite you to read about Pluto.
However, in 2006 the International Astronomical Union ruled that Pluto a planet could not be estimated, and therefore Neptune became the furthest again.
2. Neptune is the smallest of the gas giants
Neptune has a radius of 24.764 km, which makes it smaller than Saturn, Jupiter and UranusThe interesting thing is that it has 18% more mass than Uranus, so it's smaller but also denser. For more information about Uranus and its comparison to Neptune, you can consult the characteristics of Uranus.
3. The gravity in the Neptune area is almost similar to Earth
If we managed to stop on Neptune, we would find that gravity is only 17% stronger than on Earth. Of all the stars it is the most simulated to ours. Neptune has 17 times more mass than Earth. Earth and is 4 times larger. Therefore, it has more mass to spread out in that location, making the gravity similar to that found on Earth. To better understand gravity on the different planets, you can read about the value of gravity on the planets.

4. There are debates about the finding of Neptune
There is a dispute between the British and the French over who found Neptune. The French Urbain-Leverrier and Englishman John Couch Adams announced that a new planet would be stumbled upon in an established part of the sky. Then the astronomer Gottfried Galle located it, and both mathematicians took the credit, setting up a fight between England and France.
5. Neptune is the most frigid world in the Solar System
Another of Neptune's curiosities is its temperature since it can go below 221,4 °C, being the coldest star in the world. Solar systemCyclones of 2.100 km/h (XNUMX mph) are caused there, which intrigues scholars, as such a cold planet couldn't possibly have so many rapidly moving clouds. One hypothesis is that the low temperatures and gas emissions exert friction, creating stormy winds.

6. This planet imprisoned Triton
Triton It is Neptune's largest moon and has a reactive orbit, which means it moves in the opposite direction to the other moons. This symbolizes that it was not established like the other moons, but was taken by Neptune's gravitational pull. Triton is one of the coldest regions in our Solar System, with temperatures below 235 °C. Despite its cold weather, it has craters and geysers with liquid nitrogen. If you're interested in knowing how many moons Neptune has, you can visit how many moons does neptune have.
7. Neptune was only frequented once
Another interesting fact about Neptune is that the only spacecraft to travel there was Voyager 2, during its Grand Tour of the Solar System. It passed within 3 kilometers of its north pole in 1989, the closest the spacecraft ever came to a surface. It assimilated its atmosphere and rings, as well as its moons. NASA has tentative plans to send a ship in 2016 that will reach Neptune 14 years later, in 2030. For more details about space travel, you can check out our article on manned trips to space.

8. Neptune has rings
If we say ringsMany people only think about Saturn's enticing rings. But did you know that Neptune also has its own ring system? Unfortunately, their expectation is hampered because they are much darker. In total, Neptune has five rings, named after astronomers who created significant discoveries about this planet: Galle, Le Verrier, Lassell, Arago, and Adams. To learn more about the gas planets, you can visit our article on gaseous planets.
These rings are made up of at least 20% dust (some regions get up to 70% dust), whose atoms they are analogous to those learned in the rings of Jupiter. The rest of the ring materials are made by rock girls. It is found that the rings are dark due to the representation in them of organic arrangements that have been disturbed thanks to cosmic irradiation, an anomalous thing that has also been noticed in the rings of Uranus.
Neptune's rings are thought to be comparatively new (much younger than those of Uranus) and that could correspond to the result of a clash between some of the unique moons of the planet that saw their orbits upset when Neptune gravitationally imprisoned Triton, from which it is fused that it was a body that originally constituted part of the Kuiper Belt.

Finally…
One of the curiosities of Neptune is that it is a ball of gas and ice (and perhaps a nucleus rocky), so if we stood on its clouds, we would sink. But we would realize something extraordinary: the force of gravity that excites us downwards would be about the same momentum as the one we feel walking on Earth.
Likewise, another of Neptune's curiosities is that its gravity is only 17% higher than that of Earth. Earth, the closest figure that can be found in the Solar System.
In another sense, the discovery of this planet remains a subject of debate since the first person who surely observed Neptune was Galileo, who printed it as a star in one of his drawings. And since he could not identify it as a planet, his disclosure is not imputed to him.
This value belongs to the French mathematician Urbain Le Verrier and also to the English mathematician Couch Adams. Both scientists announced the presence of a Astro in a certain area of the sky.
On the other hand, the largest moon of Neptuno, has a retrograde orbit, in other words, it orbits in the opposite direction to how the rest of the planet's moons do. This particularity is explained by indicating that, perhaps, Neptune gravitationally stopped Triton, its moon. So, the moon was not formed along with the rest of the other moons.
In the same way, another of Neptune's curiosities is that the only time we have visited it was thanks to the Voyager 2 probe. And this happened on August 25, 1989. Finally, the wonderful photographs taken by Voyager 2 could be the best Neptune chips we have for decades to come. However, the flagship mission of the NASA, could take part sometime during the 2020s or 2030s.
And in the same way, NASA proposed last 2003 a mission to Neptune analogous to Cassini, which orbits the Saturn today. This mission is known as Neptune Orbiter, and there is no more information about it.
In short, another of the curiosities of Neptune is that another proposal has been the Argo probe, a spacecraft that would be launched in 2019 and whose purposes would be to cross Jupiter, Saturn, Neptune, and an object of the belt of Kuiper. Effort will focus on Neptune and its largest moon, Triton, which would be achieved in the year 2029.
