Questions about the existence of ninth planet on the edge of the solar system

At present, scientists’ latest research raises further questions about the existence of the ninth planet on the edge of the solar system. It is reported that since the scientists first proposed the concept of the ninth planet in the solar system in 2014, the debate about its existence has continued.

Now researchers say that the signal detected outside the orbit of Neptune may not be a mysterious unknown planet, but a disk-like structure composed of several cold and cold objects, the total mass of which is about 10 times the mass of the earth. Antranik Sefilian, a co-author of the study and a Ph.D. student in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, UK, said: “The Ninth Planet Hypothesis is very interesting. If it does exist, why has it not been detected so far? What is its trace? We believe that instead of guessing that the ninth planet may have special structures and unusual orbits, why not simply consider the gravitational force formed by the disc-shaped structure of small celestial bodies outside the orbit of Neptune. ”

The study, published in the Journal of Astronomy, attempts to explain some unusual elliptical orbits across the Neptune celestial bodies (TNOs) that operate in the Kuiper Belt and beyond, without the ninth planet. At the same time, they found that the gravitational forces of the disc-shaped small celestial structures allowed them to exhibit such strange orbital structures.

Sefilian said: “If you remove the ninth planet from the model and allow a large number of small objects to be scattered in a vast space, the common gravity between these objects can easily explain that we look at some celestial bodies across the Neptune. The eccentric orbit to.”

Researchers from the University of Cambridge in the United Kingdom and the University of Beirut in the United States simulated the relationship between the Neptune celestial bodies and large external planets. They believe that there are huge disc-shaped structures made up of small celestial bodies outside the orbit of Neptune. Based on this simulated structure, they find it possible to explain the existence of about 30 unusual cluster orbits of celestial bodies across the Neptune.

At the same time, the researchers also determined the quality parameters of the disc-shaped structure, its roundness and its direction gradual process. The researchers said that in order for this latest hypothesis to be established, the total mass of disc-shaped structures must be several times the mass of the Earth, up to a maximum of 10 times. When we look at other stellar systems, we often study the disc structure around the star to infer the properties of the planet around it.

The problem, however, is that as the astronomer observes the disc-like structure from inside the solar system, it is almost impossible to see the entire disc-like structure at a time. Although we have not directly observed the existence of this disc-shaped structure, we do not have evidence of the existence of the ninth planet, which is why we are investigating other possibilities.

It is worth noting that by observing celestial bodies around the other stars like the Kuiper Belt and analyzing the planetary formation model, we will find a large number of celestial bodies. It is also possible that both interpretations exist – there is a ninth planet and a huge small celestial disc. As each new Neptune celestial body is discovered, we will collect more evidence, which will help explain these. The characteristics of the celestial body.

What is the mysterious “ninth planet”?

Astronomers believe that the orbit of many celestial bodies in the distant parts of the solar system is disturbed by an unidentified planetary gravitational pull. The California Institute of Technology research team first proposed the concept of the existence of this mysterious planet. They believe that the distant orbit of the icy object can explain the existence of mysterious planets.

To prove that it coincides with the observed data, this mysterious planet is called the “ninth planet”. It is about four times the size of the Earth and ten times the mass of the Earth. According to the researchers, the volume and quality celestial bodies can explain the existence of many icy small celestial bodies outside Neptune. Their large orbits mean that these small celestial bodies need 1-2 million years to run around the sun for a week.

The theory of the ninth planet is based on its gravitational force on these celestial bodies, which astronomers believe may be discovered in the next few years. And some astrologers and science fiction writers suggest that this is a planet of the size of the Earth. It “behind the sun” is related to the end of the world and may have to continue searching.
