Do you think the discovery of a new celestial object on the edge of the solar system will help peopl

According to the first edition of the "Science" magazine on the 18th, astronomers have confirmed a distant icy world, which is located at the very far end of the solar system, and it takes 20,000 years to make one revolution, and its orbit is far beyond Pluto. The object is currently tentatively named L91, and its special position and orbit may lead mankind to discover the true "ninth planet" of the solar system.

It is not difficult to conclude that, in addition to being bound by the gravitational pull of the sun, there must be a large planet interfering with it. While it's quite attractive for scientists to explain the strange trajectory of Sedna and similar celestial bodies in terms of the possible presence of the ninth largest planet, the hidden Planet X, it's not the only explanation. This elongated orbit may also be caused by the tidal action of the Milky Way.

Now, we have named the ninth largest planet X, and planetary scientists are applying for a large integrated survey telescope to get a clue to Planet X. Perhaps, one of the stars that looks up is the ninth planet we are looking for. ‍‍

Unknown world, anything is possible....

Explore the orbit to see if there are more similar stars to discover the larger conspiracy behind them, and further track down a potential Planet Nine. But this discovery may still take a long time, and the efforts of scientists are indispensable. will be confirmed.

The news about Planet 9 has never stopped, and since Pluto was removed from the solar system in 2006, astronomers have never stopped looking for planets.

In 2006, astronomers removed Pluto from the "Nine Planets" of the solar system. People have gradually become accustomed to the "eight planets", but astronomers have not given up on the search for the real ninth planet, or "Planet X". Now, they may be close to that goal.

I think it should be, the current technology is so advanced, maybe there will be new discoveries in the near future.

For the big planets in the inner solar system, gravity will throw the outer planets out, instead of pulling them on themselves. It's like the Earth keeps pushing the Moon outward. So, the existence of an outer asteroid does not require a larger planet further away. ‍‍

Again, this is using inaccurate information, and scientists are just guessing.

Earth is one of the eight planets in the solar system and is located in the habitable zone. The emergence of life is an important sign that the Earth is different from other planets. It may well be a unique planet in the universe.

In the process of human exploration, in addition to the Earth's environment and related information, scientists are also committed to exploring the history of the entire solar system, and the discovery of the ninth planet has become an important research topic. It is generally accepted that the ninth largest planet in the solar system is Pluto, which was later excluded.

Because it does not meet the classification criteria for planets in terms of size, gravity, etc., it is classified as a dwarf planet and orbits alone at the edge of the solar system. Scientists often believe that the solar system also follows a law from disorder to order. Billions of years ago, countless celestial bodies were distributed in various regions of the solar system.

With the continuous formation of gravity and the influence of various factors, stable celestial orbits have emerged, and they are still changing, but this change is not easy to detect, and people need to observe it with the help of advanced instruments.

On this basis, the ninth planet can also be calculated by gravity and other formulas. Based on the current gravitational distribution of the solar system, scientists speculate that there is still a ninth planet around the solar system. According to the process of human exploration of the solar system, all celestial bodies were not discovered at the same time.

With the continuous progress of human science and technology, our exploration methods are also constantly updated.

Therefore, the ninth planet has not been found so far, which is most likely limited by technical conditions. Scientists have discovered a strange celestial body near the solar system. Its gravity is very large, and its volume is dozens of times that of Earth, which is in line with people's imagination of the ninth planet.

But relatively speaking, it is very far away, and it is difficult for people to explore its true situation in a short period of time, and if the speculation of scientists is true, it needs some corresponding updates and information about the solar system.

The exploration of the solar system has never stopped. After the nine planets removed Pluto, many people hope to find another one to fill the gap.

As a result, some people have raised new conjectures that there may be a new one behind the sun. It sounds a bit ridiculous, but what is the basis for this conjecture?

In 1767, the mathematician Euler deduced three special solutions as L1, L2, and L3 based on the rotating two-body gravitational field, and these positions are gravitational equilibrium points.

Among them, L1 and L2 are visible from the Earth (Geosolar system) because they are on both sides of the Earth, while L3 is located on the back side of the line between the Sun and the Earth, and cannot be seen on the Earth! In 1772, the mathematician Lagrange deduced that the other two points (special solutions) were L4 and L5, and several equilibrium points in the gravitational field of the two bodies were found!

However, among these 5 Lagrangian points, only L4 and L5 found by Lagrange are stable, and the other three are unstable, because these three forces are in a straight direction, so they can leave this region after a slight transverse disturbance, thus breaking this equilibrium, while the forces at 4 and 5 points are restrained by the earth and the sun at the same time, and will return to this point after a slight disturbance!

Therefore, the objects on L4 and L5 can exist for a long time, for example, there is a Trojan Group and Hellenic Group asteroid aggregation area in Jupiter's orbit, which is the gravitational equilibrium points L4 and L5 of Jupiter and the Sun!

Lagrange points of Jupiter and the Sun with asteroid groups.

The conclusion is simple: on the other side of the Sun, on the other side of the Sun-Earth line, if there is another Earth, then it will gradually break away from that point over a long period of time, and thus swing in orbit, and eventually collide with the Earth, perhaps this is how Theia collided with the Earth to form the Moon!

American science** has reported that they have indeed discovered the ninth planet at the edge of the solar system, to be exact, it is a black hole, but more scientific evidence is needed to prove its existence.

The solar system is so big, and there are many planets that we haven't discovered, and I think there should be nine planets at the edge of the solar system, but we can't be sure yet.

There is not necessarily a ninth planet, as scientists are not very sure.

Pluto is one of the nine planets of the solar system!

Since Pluto was kicked out of the club, there are eight known planets in the solar system, but for a while, there was some evidence that there might be one more. A hypothetical Planet Nine lurks at the outer edge of our solar system. So far, this world has not been discovered, but a new study has determined that it should be in**.

The evidence for Planet 9 comes from its gravitational pull on other objects. If the planet exists, its gravitational pull will affect the orbits of other planets. So if something seems to be pulling at a planet, you can find the source with a little math.

This is how Neptune was discovered, when John Couch Adams and Urbain Le Verrier independently noticed that Uranus seemed to be being pulled by an invisible planet.

In the case of Planet 9, we do not see any gravitational effect on the planets, but there are no planets outside the cluster of ice bodies outside the solar system known as the Kuiper Belt Objects (KBOs), whose orbits are randomly aligned within the orbital plane of the solar system. But instead, we see that a lot of KBOs are clustered in the same direction.

Back in 2016, the authors studied the statistical distribution of KBOs and concluded that this cluster was caused by an undiscovered outer planet. According to their calculations, the ninth planet has a mass of 5 Earths and is about 10 times the distance from the Sun from Neptune. The ** even calculates the vast area of the sky where the planet might be located.

The new study revisits the original work in light of some of the criticisms it has received. A big criticism is that celestial bodies outside the solar system are hard to find, so we look for them in convenient places. The aggregation effect we see may simply be due to biased data.

Considering observational bias, the authors found that clusters were still statistically unusual. It only has the opportunity for uncertainty. When they recalculated the possible orbit of Planet Nine, they were better able to determine where to look.

An interesting aspect of this research is that the newly calculated orbit brings Planet 9 closer to the Sun than originally thought. This is strange because if it was closer, then we should have spotted it already. The authors believe that observations to date have ruled out the closest option for Planet Nine, which helps to further narrow down its possible location.

If the planet exists, then in the near future it should be detected by the Vera-Rubin Observatory.

Of course, this study is not conclusive, and many astronomers still believe that Planet Nine does not exist. But this study makes it clear that we don't have to argue about it for too long anymore. Either it will be discovered soon, or the observations will rule it out as an explanation for the KBO aggregation effect.

According to the news, researchers have discovered a new extrasolar planet. The exoplanet, named Gliese 486b, is located 26 light-years from Earth and orbits a smaller, cooler, and fainter red dwarf star compared to the Sun, making it one of the closest exoplanets to Earth.

The main purpose of people searching, discovering, and studying planets is to find out whether there is life beyond the earth and whether there is a "new continent" habitable for human beings. The newly discovered Gliese 486b, as a rare neighbor of the Earth in the universe, is of course also pinned on high hopes.

It is estimated that astronomical observations confirm that due to its proximity to the parent star, the surface temperature is as high as about 430 degrees Celsius, and the extremely hot and dry Gliese 486b is probably not suitable for life.

In fact, it is not necessary to rely on astronomical observations to make a judgment about whether there is life in GLISE486b and whether it is habitable.

First of all, Gliese 486b will certainly not have a life civilization comparable to that of humans on Earth, let alone a civilization that is higher than that of humans on Earth.

Because if such a civilization existed in Gliese 486B, more than 100 years after humans on Earth invented radio and transmitted information, Gliese 486B civilization should have received and responded to it, right?

However, no.

So, is it possible for low-end life to exist?

Let's put that aside and ask whether Gliese 486b is livable.

At present, it seems that Gliese 486b is dry and hot on the surface, and even if it has an oxygen feast and low-end life that can be eaten, it is certainly not suitable for human habitation on Earth.

Of course, humanity is looking forward to the future.

When will this future be?

26 light-years away, Gliese 486b, with the ability to travel to the stars known to mankind today, is an unimaginable future.

More importantly, the parent star of Gliese 486b is a red dwarf. Red dwarfs are the old age when stars are dying of life. The future of Gliese 486b will be a process of getting closer and closer to the parent planet and getting hotter and hotter until it is eventually engulfed by the parent star and ends up with the parent planet.

The sun, on which the earth depends, is still in the prime of its stellar life. It is necessary for humans on Earth to observe and recognize the present and future of Gliese 486b. However, these cognitions are probably only the significance of the Earth's cognition of the solar system and the process of the Earth's life, and by no means the significance of human migration to Gliese 486b.

Obviously, in the absence of the possibility and necessity of human beings on Earth to migrate to Gliese 486b, even if it is found that Gliese 486b does have low-end or high-level life, it is of no practical significance to human beings except for the psychological comfort that life is not lonely in the universe.
