Antiques Astronomers The idea that there is another world in our solar system, commonly known as Planet Nine, has been around for years, and Japanese astronomers have now discovered another “Earth-like” planet nearby. Earth.
According to the British newspaper “Daily Mail”, they believe the new planet is hidden in the Kuiper Belt, a cake-shaped ring of objects that extends beyond Neptune’s orbit.
The Kuiper Belt (KBP) is about 500 astronomical units (AU) from the Sun, which is 500 times the distance between Earth and the Sun.
Experts say KBP has three times the mass of Earth, but its temperature is too cold to support life as we know it.
The study was led by Patrick Sophia Ligoka of Kintai University in Osaka, Japan, and Takashi Ito of the National Astronomical Observatory of Japan in Tokyo. “We expect an Earth-like planet to exist,” they said in their paper. Journal of Astronomy.
“Because there were so many such objects in the early Solar System, it is plausible that an ancient planetary body could survive in the Kuiper Belt KBP,” they added.
The Kuiper Belt contains millions of icy objects that lie beyond Neptune and are referred to as Trans-Neptunian Objects (TNOs).
TNOs are thought to be leftovers from the formation of the Solar System, made up of rock, amorphous carbon, and volatile ices such as water and methane.
“The orbits of trans-Neptunian objects (TNOs) may indicate the existence of an undiscovered planet in the outer solar system,” says the Japanese team, adding that some of these objects have “special orbits” that indicate they are gravitationally affected by something. Near the big one.
The belt contains a large number of high-inclination objects, which have high inclinations as they orbit the Sun.
