Is the ninth largest planet in the solar system possible? A strange phenomenon let it show its feet

Once upon a time, there were nine planets in the solar system. I believe many of my friends introduced the nine planets in the solar system when they went to school. It spread a lot. Until now, many people talk about the planets in the solar system, and they are used to calling them the nine planets. But later, the International Astronomical Union formally defined the concept of planet, Pluto did not meet the new definition of planet in terms of mass and volume, so it was excluded from the planetary range and classified as dwarf planet. Since then, the solar system has only eight planets.

The solar system has changed from nine planets to eight planets, which makes many people feel very uncomfortable at the moment, because the word “Nine” has a very important meaning, such as “nine to one” and “nine stars in a row”. Many legends in history are related to nine stars. In recent years, some scientists have proposed that there should still be a planet in the solar system that has not been discovered by human beings. This planet may be the new ninth largest planet. If this planet is discovered, the solar system will return to the age of nine planets.

Why do scientists predict that there should be another planet in the solar system? This is actually a guess made by scientists based on the abnormal orbit of some asteroids on the edge of the solar system. Scientists think that the ninth planet may be near the edge of the solar system, which we’ve heard of in the Kuiper belt. Although it has been several decades since mankind went out of the earth to explore the universe, and we know a lot about the solar system, the edge of the solar system is still a blind area for human exploration, especially the Kuiper belt.

The main reason why it is difficult to observe the edge of the solar system is that it is too far away from the sun and the light reflection is very weak, so it is not easy for astronomical telescopes to observe. The reason why scientists speculate that there may be a massive planet on the edge of the solar system is that when scientists study the six objects in the Kuiper belt, they find that their orbits are abnormal.

Although the six celestial bodies operate at different speeds, their orbits have the same inclination angle, and the angle toward the sun is similar. Under natural conditions, the probability of this happening is only 1 / 14000 (0.007%), so there is another case that the gravity of a relatively large planet affects the orbits of the six celestial bodies.

Scientists named the possible planet as lucky star, which is about 10 times the mass of the earth and is a huge gaseous planet. If it does exist, Jupiter’s position as the number one planet in the solar system will not be guaranteed and will be replaced by this happy star. It takes 10000 to 20000 years for this unknown planet to orbit the sun. This orbit is very large, which also increases the difficulty of finding it. It may exist in any position.

The Kuiper belt is located outside the orbit of Neptune, near the ecliptic surface about 40-50 astronomical units from the sun, and is a disk-shaped hollow area with dense small objects. The most famous object in the Kuiper belt is Pluto, which is about 2300km in diameter and has been downgraded to a dwarf planet. Among the objects observed in the Kuiper belt, there are at least a dozen with a diameter of several hundred kilometers, and the number is still increasing.

If there really exists such a giant planet in the Kuiper belt on the edge of the solar system, which is 10 times heavier than the mass of the earth, its existence will inevitably affect the orbits of many objects in the Kuiper belt. Now scientists are still observing and discovering more abnormal objects in the Kuiper belt. If more and more abnormal objects can be found, it will be a great challenge for science The more certain home will be of the existence of this huge unknown planet.

Now scientists have started the work of searching for this planet, but it is very difficult to find it. The reason is that it is too far away and can reflect very little sunlight. This is the same as looking for a coal ball in a pile of coal. There is no obvious light, so it is difficult to see. More importantly, if you want to find this planet, you must have a strong sky Wen telescope, our current astronomical telescope may not be able to do this task. Scientists hope that when the world’s largest optical telescope, the large Magellan Telescope, is completed in 2021, it may be possible to observe the unknown planet.

Although it’s interesting to say that the solar system has unknown planets, most astronomers are cautious about this idea. They think that more evidence is needed to accept the idea that a ninth planet will reappear in the solar system. Of course, scientists who believe that it exists will not give up their research and search for it. If it really exists on the edge of the solar system, we believe that it will not escape the eyes of the advanced detection equipment of human beings in the future.

In fact, the main reason why it is very difficult for human beings to find the ninth largest planet is that the technology of human beings is still relatively backward. One of the main reasons is that the speed of our aircraft is too slow. If the speed of human spaceship can reach sub light speed, our probe and spaceship can easily reach the edge of the solar system. At that time, we can launch probes around the solar system, let them reach the Kuiper belt on the edge of the solar system, and search for the planet from different positions.

As long as our detectors are widely distributed and close to the Kuiper belt, it is not very difficult to find this huge planet if it exists. Anyway, it is also a planet larger than Jupiter. The main reason why we can’t find it is that it is too dark, there is no reflection of sunlight, and we can’t see it from a long distance. However, if we detect near the Kuiper belt, we can see it because of its close distance The possibility of detection is very high.

Unfortunately, at the speed of human spaceships, it will take us decades to reach the Kuiper belt, so we can’t use the detector to explore in a large area. If we fly at sub light speed, it may take us a few days to reach the Kuiper belt. Some people may say that there is a new horizon spacecraft in the Kuiper belt on the edge of the solar system right there to carry out observation missions? Is it possible for it to find this unknown planet?

In fact, this probability is very small. You should know that the Kuiper belt is around the entire solar system. The cycle of this unknown planet may reach 10000-20000 light-years. The orbit range is too large. Unless it runs right near the location of new horizons, new horizons will be able to find it, or it will not be able to find it.

Although the existence of the ninth planet is only a conjecture of scientists, and there is no exact evidence and data to prove its existence, it is believed that with the continuous progress of human science and technology, through the observation and research of scientists, there will be updated observation data in the future, which can also reveal the secret of its existence. However, many people still hope that it will exist, so that the solar system will return to the nine planets again.
