Accept the ninety planetary hypothesis? The strange job of heavenly bodies can be explained by "summary" | TechNews



The ninth planet is a powerful and wonderful hypothesis that explains why some of Neptune's exteriors have a whole eccentricity (long elliptical pathways), but scientists have never found the ninth planet, which makes # 9; It doesn't make their existence controversial. Another group of astronomers believe that we do not need the ninth planet. New studies have suggested that a large mass of discs consist of a large number of small skies outside of Neptune. Gravity forces can influence and lead to some parts of Neptune. Unusual pathways appear.

Trans-Neptune object (TNO, extraterrestrial celestial body), as its name implies, runs into Neptune's mountain, where the Cooper celestial body (CBO), discrete holistic bodies, independent halves, Celeda skies, and Otto clouds . Religious bodies (ICO / OCO), etc.

Since 2003, astronomers have discovered about 30 invalid TNOs with high eccentric traces, the existing eight-planetary system cannot form heavenly bodies in the form of this trajectory. Therefore, the geophysical physicist Konstantin of the Kalifrian Institute for Text Konstantin Batygin and Mike Brown have postponed the idea of ​​the concept of "Ninth Planet" in 2016. The quality is about 10 times that of the earth, and its size can contain these TNO objects.

The orbital extinction (s) is an important parameter that determines the shape of a circle. In simple terms, the smaller the ex-intensity, the closer the & # 39; the orbit is in a circle, like the earth, the greater the ex-intensity, the counter the orbit is to some narrow ellipse. Circular orbit: e = 0, ellipse orbit: 0 <e <1.

But nobody can find the ninth planet to prove this.

Antranik Sefilian, the first author of & # 39; s study and an astrophysicist & # 39; A University of Cambridge in the United Kingdom, said that setting the ninth planet it is easier to believe that there is a large mass of large sky types outside of Neptune, how & # 39; t the gravitational effects of & # 39; do the aggregates affect TNO?

The research team combines the disc with the solar system for simulation of computers, the model has lost the ninth planet, and it has changed into many smaller companies in a broad floor plan, making the disc a bit of & # 39; to explore high eccentricity of TNO. Track.

Famous ideas were replaced in June last year by the University of Colorado Boulder astrophysicist Ann-Marie Madigan and Jacob Fleisig diplomat, who said that a thousand discovered small objects are in the "mind direction".

All in all, as it says, these two theories are probably unbeatable before we find more superficial bodies and make enough models. The new paper was published in Astronomy magazine.
