Japanese astrophysicists from Kindai University and the National Astronomical Observatory of Japan have discovered possible evidence of an Earth-like planet located in the Kuiper belt, at the outskirts of the solar system. To work published In the scientific journal The Astronomical Journal.
The Kuiper Belt lies beyond the orbit of Neptune and consists of numerous asteroids and other celestial bodies, including the dwarf planets Pluto, Haumea, Makemake, and Eris.
In their study, the researchers found that some Kuiper belt objects behave as if they were affected by the gravitational field of a planet comparable to Earth.
Models showed that if such a planet existed, it would have 1.5-3 times the mass of Earth and would lie between 37.5 billion and 75 billion kilometers away, which is 250-500 times its distance from the Sun. between the Earth and the Sun, respectively.
Earlier astronomers opened Record-breaking compact star system that can fit inside the Sun.
