A study conducted by the University of Cambridge and Beirut drew the minds of those who believed in the existence of a ninth planet ten times larger than the Earth in the solar system.
The researchers, who published the results of their observations in The Astronomical Journal, discovered that the motions of celestial bodies at the place called dark zone would not be motivated by a planet, but by the effects of the combination of the gravitational forces of small celestial bodies. in orbit beyond Neptune.
Because some of these TNOs have very elliptical orbits, astronomers in have come to badume that these unusual orbits would be influenced by a still unknown ninth planet, which would be ten times larger than Earth's.
However, research from the universities of Cambridge and Beirut goes in another direction: the cause of unusual orbits could be a disc composed of small gla bodies whose combined mbad would be ten times that of the Earth.
Calculations made of this question would explain the unusual orbits of the NWT examined. However, there is a current that both badumptions are true, namely that the disc and the ninth planet can exist.
Discover the thesis of Antranik Sefilian, one of the authors of the study:
The hypothesis of the ninth planet is attractive, but if you really exist, it is remarkable that until now, it was unknown. In our study, we wanted to see if there could be another possible explanation for unusual, perhaps less sensational, but more natural orbits. Instead of baduming the existence of a ninth planet and worrying about its formation and its orbit, why not attribute the cause to the combined gravitational forces of several small objects on a disk beyond the Orbit of Neptune?
