When he first assumed the mysterious "ninth planet" in 2016, he was hailed as the agent of the strange orbit of distant glaciers and unexplained glaciers in the solar system, but despite extensive research on the planet using the most powerful observatories, no one has found it; Astrophysics is a less dramatic interpretation of what is happening in our system.
Instead of a large planet affecting the orbit of bodies beyond Neptune, two scientists believe that these objects are attracted by the combined force of a large disk of small ice particles orbiting the Sun behind Neptune.
The new hypothesis was developed by astrophysicist Antranik Cevillian of the University of Cambridge in the United Kingdom and by Jihad Touma of the American University of Beirut in Lebanon.
If this sounds familiar, Cevilian and Thomas are not the first to propose this idea, but their calculations are the first to explain the specific advantages of the strange orbits of these objects, taking into account the other eight planets of the system. solar.
To this end, researchers have developed a computer model of the outer orbit beyond the orbit of Neptune (TNO), as well as planets and planets of the solar system, as well a huge disk of debris beyond the orbit of Neptune.
By applying some modifications to elements such as mass, anomalies, and disc orientation, the researchers were able to re-establish orbits in orbit behind Neptune.
"If I remove the ninth planet from the model and, instead, allow many small objects to extend over vast expanses, the gravitational attraction between these objects can easily explain the strange ones." orbits that we see in some objects beyond Neptune, "said Cevilian.
However, this hypothesis is also uncertain, as is the case of the ninth planet. "Although we have no direct evidence of disk playback, we also have no evidence of the ninth planet, which is why we are exploring the possibilities," Cevilian said. Other ".
"It's also possible that both things are true, there can be a huge disk and a planet, and every time we discover new discoveries beyond Neptune, we collect more evidence to help explain its behavior."
