Does the ninth planet exist? To this, scientists have a new explanation and answer

The solar system is the parent galaxy of human existence. Once upon a time, there were nine planets in the solar system, and nine numbers are of extraordinary significance to human beings. Naturally, the nine planets also make people feel very comfortable and friendly. But in 2006, at the 26th International Astronomical Union, scientists thought that Pluto’s mass was too small. If it was a planet, the mass of asteroid Eris was 27% higher than that of Pluto, and it should be the tenth largest planet.

For this reason, scientists decided to kick Pluto out of the list of planets, and the solar system has changed from nine planets to eight planets. For a time, many people find it hard to accept it, and the eight planets are not as comfortable and friendly as the nine planets. Therefore, when many people describe the solar system, they still call it nine planets.

In early 2016, astronomers Mike Brown and Constantine batijian published a paper “evidence for the existence of a distant giant planet in the solar system”. In this paper, we analyzed some orbital anomalies of objects in the Kuiper belt on the edge of the solar system. One answer that can explain these anomalies is that there is a planet 10 times the mass of the earth outside the solar system, which is the ninth planet Planets.

After scientists put forward the conjecture about the existence of the ninth planet, many scientists began to focus on the edge of the solar system. Through observation and research, they found that there are indeed many abnormal orbits of celestial bodies here, and there is no way to answer this anomaly with other explanations. There is only one possibility, that is, there is a greater gravity that affects their orbits and brings about this huge gravitational force It could be the ninth planet.

Later, the two astronomers who proposed the ninth planet conjecture published “orbital aggregation in the far regions of the solar system” and “the ninth planet hypothesis”. In the book orbit gathering in the far regions of the solar system, the authors put forward such a view: either there is a ninth planet, which shapes the orbit of the far objects in the solar system, or there is a deviation in the observation results.

The author of the ninth planet hypothesis points out that understanding the structure of the solar system is one of the oldest pursuits of mankind and one of the biggest challenges in the field of natural science research. In this paper, the author again puts forward the view that although many orbital behaviors of distant objects in the Kuiper belt can be easily explained and predicted by the eight planets, some behaviors cannot be explained in this way.

From the convergence of the orbital semimajor axis of more than 250 astronomical units, to the separation of Neptune from the perihelion of the selected objects in the Kuiper belt, to the dynamic origin of the highly tilted / retrograde long-term orbit, it would be meaningless if we only use the eight planets to explain these phenomena.

More and more evidences show that there may be a huge gravitational source on the edge of the solar system, which leads to the abnormal orbits of many objects in the Kuiper belt. More and more people think that this huge gravitational source is caused by a planet whose mass is 10 times that of the earth.

So is this massive object really a planet? If this is a planet, it could be a super earth. At present, there is no consensus in the astronomical community, but we suspect that this massive object is the ninth largest planet in the solar system. From the mass point of view, its status is the same as that of the earth, and it belongs to the planetary level.

If this massive celestial body is a planet, its origin is worth pondering. Scientists believe that there is not enough material at the edge of the solar system to form such a massive celestial body. If it exists, it may come from outside the solar system. It may be a stray star. When it passes through the solar system, it is captured by the sun’s gravity and becomes the outermost star It’s our planet.

However, scientists have put forward a new idea that the massive object at the edge of the solar system may be a primary black hole. The primary black hole began to form in the period of cosmic inflation. Physicists call the universe before the big bang the primary universe. In the primary universe, if there is a special fluctuation in the energy density of the cosmic space, when the energy density of the local space gathers to a certain extent, it may form the seeds of the primary black hole.

Then, with the evolution of the universe, the seeds of these black holes will continue to accrete the particles around them, thus forming primary black holes. According to scientists’ research on the primary black hole, the mass of the celestial body in the conjecture on the edge of the solar system is also within the mass range of the primary black hole.

If this object is a primary black hole, then its mass is reasonable, and because the primary black hole does not emit light, the Hawking radiation temperature of a primary black hole with 5 times the mass of the earth is lower than 0.0001 Kelvin, so it is impossible for us to find this primary black hole through Hawking radiation. This also explains why human beings can not see it directly by optical means, but can only infer its existence by gravitational field effect.

Now it is more and more interesting to explore the massive object that may exist at the edge of the solar system. There are two possible answers, one is a huge planet, the other is a primary black hole. In either case, they can produce a huge gravitational impact on the objects in the Kuiper belt on the edge of the solar system, thus affecting their orbits.

For scientists, they may prefer it to be a primitive black hole, which can be said to be the most mysterious and powerful celestial body in the universe. At present, we know very little about black holes, and the data about black holes are obtained from the horizon of those supermassive black holes. They are very far away from the earth. The nearest black hole is the one in the center of the Milky Way galaxy, which is 25000 light-years away from the earth. The black hole in the first black hole photo of mankind is 65 million light-years away from us.

If we want to really understand black holes, we will be able to observe them at close range. However, we have not yet found such black holes. If there is a primary black hole at the edge of the solar system, although the black hole is very small, it is of great significance for human beings to study and explore the mystery of black holes.

If scientists find this massive object outside the edge of the solar system in the future, it will be a small black hole. It is believed that scientists will send detectors to detect it. It may also become a target that scientists focus on. It may also be an excellent opportunity for human beings to reveal the secrets of black holes.

Of course, the existence of the ninth planet is still in the stage of conjecture. Although there is a lot of evidence that such a celestial body is likely to exist, it is normal if it is found that it does not exist in the end. Or if it is found to be a black hole, then people’s dream of the ninth planet will also be shattered, but at that time, a small black hole on the edge of the solar system was not a bad thing.
