The International Astronomical Union downgraded Pluto from a planet to a dwarf planet, reducing the number of planets in the solar system from nine to eight.
Since then, the distribution of planets and planetary belts in the solar system has been re-discussed, and finally the astronomical community of various countries has agreed with the decision of the International Astronomical Union.
However, although Pluto is no longer a planet, the rumors about the ninth planet have not gone away, and have even intensified.
Some people say that it is Planet X, while others believe that it is a low-mass black hole, and in recent years, anomalies in the orbits and positions of some planets in the outer solar system have been used as evidence of this black hole.
As two scientists from Harvard University put forward their opinions, various speculations are being made about the solar system in order to confirm this possibility, which has been recognized by Harvard University as the low-mass black hole is Planet Nine.
It is impossible to confirm that the reason for its existence is precisely because of this low-mass black hole, and the opinion of two scientists at Harvard University on how to observe it, and whether there are technical difficulties in such observations.
1. There are low-mass black holes outside the solar system.
The idea that Planet 9 could be a low-mass black hole was proposed by two scientists at Harvard University, Dr. Scott Kenton and Dr. Frank Hersha.
According to their research, the mass of this low-mass black hole should be between four and ten times the mass of the sun, that is, it should be a black hole, so now this low-mass black hole should be a less active black hole, without accretion of the surrounding environment, so there is no way to emit light.
At the same time, the accretion of this low-mass black hole is relatively small, so the accretion rate is relatively slow, if the low-mass black hole does not have the accretion of the surrounding environment, it can also move independently in the outer side of the solar system, and it does not necessarily have to have the material of the surrounding environment for accretion, so it is indeed possible for the low-mass black hole to exist alone.
However, such a low-mass black hole should not be the only one in the outer solar system, and it is very likely that there are more low-mass black holes in the outer solar system, but no astronomers are observing them, so astronomers have made sufficient observations of the outer space of the solar system.
However, astronomers have made sufficient observations of the outer space of the solar system, and have not found other low-mass black holes, and it is impossible for small-mass black holes to exist in such a stable area as the outer solar system.
It is possible that a low-mass black hole, like other black holes, will explode due to the movement of matter around it and radiate around it, so there will be many stars in the place where such a low-mass black hole is located, that is, it should be in the center of the Milky Way, which is a very prosperous place.
At the same time, there are also a large number of comets in the outer solar system, and it is possible that this small black hole will also attract the comet to its surroundings, so it will also change the light and darkness around it, and the comet in the outer solar system may also be the mysterious Planet X.
Despite this, astronomers have made many observations that have made many people doubt it, and no one thinks that such a small mass black hole will appear in the outer side of the solar system, because it is not necessary.
So it seems that while the theory of a low-mass black hole as the ninth planet is indeed feasible, many astronomers are questioning it, believing that there may be an orbit of the ninth planet in the outer solar system, but it is difficult for us to observe.
2. Localization by accretion flare.
Kenton had always thought that the low-mass black hole was Planet Nine, and he also named it Nebiru, which is also an ancient planet.
Kenton's choice made all astronomers explode, after all, the mysterious planet written by ancient humans, then the orbit of Nibiru should be very strange, and it can even be said that it is completely uncontrolled.
But in this way, many people think that the small-mass black hole is still very different from the Nibiru star, so the Nibiru star is originally a very strange planet, so the relationship between it and the low-mass black hole is not because it is a low-mass black hole, so that the orbit of the Nibiru star will be more different and strange.
Kenton, on the other hand, believes that there is no connection between the low-mass black hole and the Nibiru star, and he just thinks that the low-mass black hole is a dwarf planet in the asteroid belt, and that the low-mass black hole is probably near the edge of the solar system, but there is not enough light to observe it.
Moreover, such a low-mass black hole is very stable at the edge of the solar system, so it can easily maintain a stable orbit, but it is still very different from Nibiru.
Therefore, in Kenton's guess, the low-mass black hole is the ninth planet, although it is a black hole, but it can only be observed when it absorbs light, but this low-mass black hole does not have a surrounding environment to absorb light, so astronomers have no ability to observe it.
With the continuous advancement of science and technology, the edge of the solar system is also being continuously observed, and once the existence of this small mass black hole is observed, then this big discovery is also very possible.
Dr. Scott believes that this small mass black hole exists because it is very far away from the sun, so it is difficult for light to shine, but if it exists, it will inevitably become very active in its surroundings, and then it can be observed when it absorbs light.
Therefore, if astronomers want to observe it, they need to observe accretion flares, because when a low-mass black hole occasionally absorbs light, it emits a large number of X-rays, and the low-mass black hole also emits bright light, and this light hits the sun's radiation belt, and astronomers can observe it.
However, such observations have requirements for equipment and technology, because such observations require a lot of energy, but the existing technology and equipment do not have that much energy, so their observation is very beneficial.
And even if the X-rays and accretion light emitted by a low-mass black hole can reach the Earth, such observations can only be made when astronomers are observing solar activity, and astronomers do not care whether there are any small-mass black holes around the sun when observing solar activity.
And while such observations can be made at the edge of the solar system, such observations are not possible at the edge of the solar system, so in Kenton's guess, such observations do not exist.
3. There is a ninth planet outside the solar system.
In people's eyes, there may be an orbit of the ninth planet at the edge of the solar system, but it is not a small black hole, but a planet, but under such an orbit, the movement of other planets in the solar system will become very strange, because it has a very large gravitational pull, and it is undoubtedly another planet in the solar system.
So what is this other planet, and what is the opinion of astronomers?
Dr. Kenton believes that there may be a small mass black hole at the edge of the solar system, but there is no evidence for this small mass black hole, and it is very difficult for astronomers to detect and search for the edge of the solar system, and the small mass black hole cannot exist at the edge of the solar system, so their speculation is even more groundless.
Scott believes that the small-mass black hole in Kenton's view is possible and has nothing to do with Nibiru, but there are indeed many challenges and difficulties under the existing means of solar system observation and exploration.
The existing detection methods of the solar system are very rich and advanced, but the detection of the edge of the solar system is still very difficult, but the existence of a small mass black hole is only a possibility, but there is no evidence at all, so there are still many difficulties in the detection of the edge of the solar system.
Scott believes that if the mass black hole exists as the orbit of the first planet, then it will have a very large gravitational pull with other planets, so it will not exist at the edge of the solar system, but in other regions of the solar system, so the small mass black hole will not have a very large gravitational pull with other planets, so it will exist at the edge of the solar system.
Kenton believes that Scott's guess is not wrong, but other regions of the solar system also have a great gravitational pull on low-mass black holes, and it is still very difficult for small-mass black holes to exist.
epilogue
Although the hypothesis of a low-mass black hole as the ninth planet is possible, the true outcome is unknown, providing an interesting explanation.
Some scientists believe that Planet 9 is a planet, and the reference to Nibiru is also recognized, and the exploration of the unknown region at the edge of the solar system will help mankind to understand the mysteries of the universe more deeply.
