Japanese Study Hints at Earth-Like Planet in Our Solar System's Vicinity, Closer than Planet Nine

In the ongoing discussion surrounding the mysterious " Planet Nine ," which scientists have been theorizing about in the distant regions of our solar system, two Japanese researchers have recently presented a novel hypothesis suggesting the presence of a smaller, Earth-like planet that is situated closer to us than the debated Planet Nine.

The scientific community has been engaged in a prolonged discussion regarding the possible presence of Planet Nine, a theoretical large terrestrial planet. This discourse began following the reclassification of Pluto from a planet to a dwarf planet.

So far, the farthest known object within our solar system is located about 132 astronomical units away from the Sun. To provide some perspective, Pluto orbits at an average distance of roughly 40 astronomical units from the Sun.


In a recent article featured in The Astronomical Journal, planetary scientists Patryk Sofia Lykawka of Kindai University in Japan and Takashi Ito from the National Astronomical Observatory of Japan have put forward an alternative hypothesis.

They suggest the existence of a planet similar in size to Earth , with an inclined orbit around the Sun, located in closer proximity to the disputed Planet Nine.
