Kinki University in Japan recently released a press release stating that researchers from the university and the National Astronomical Observatory of Japan have successfully reproduced multiple features of Kuiper Belt objects outside the orbit of Neptune using computer simulations. The simulation results indicate that there may be an unknown terrestrial planet on the outer edge of the solar system. The research results have been published in the international academic journal Astronomy. The communique states that Neptune and the Kuiper Belt objects that exist outside its orbit are believed to be traces left by the formation of planets on the outer edge of the solar system, especially since Kuiper Belt objects may have formed unique orbits due to the continuous influence of planetary gravity. The existing typical Kuiper Belt and solar system formation models are difficult to fully explain the multiple characteristics of Kuiper Belt celestial bodies. According to the bulletin, in this study, researchers hypothesized the existence of unknown planets within the Kuiper Belt, reflected the effects of the planets in computer simulation models, and then verified this hypothesis. The simulation results can reproduce the characteristics of Kuiper Belt objects that could not be explained by previous standard models, and are almost consistent with current actual observation results. Further research by the research team has found that if there is an Earth like planet with a mass 1.5 to 3 times that of Earth and an orbital inclination of 30 degrees in an area approximately 30 to 75 billion kilometers away from the Sun, multiple characteristics of Kuiper Belt objects can be explained. At the same time, this planet played an important role in the formation of the Kuiper Belt. (New News Agency)
