"Mind-blowing Theory: Another Earth Found on Opposite Side of Sun, Solving Puzzle of Planet Formation"
Ancient theories proposed the existence of a "counter-Earth" called Antichthon hidden behind the Sun, which could explain lunar eclipses. While the idea was later dismissed, a recent study suggests that such a world could exist in other solar systems. However, observations of planetary influences and orbital calculations indicate that there is no counter-Earth in our own Solar System. The presence of an "anti-Earth" would have been detected through its influence on the positions of other planets, making it unlikely that there is another Earth on the other side of the Sun.
