"In modern times a hypothetical planet always on the other side of the Sun from Earth has been called a "Counter-Earth""
https://en.wikipedia.org/wiki/Counter-Earth

"In Philolaus’ cosmology, the earth revolves around a central fire along with the other heavenly bodies, including a planet called the counter-earth which orbits below the earth."

"The counter-earth, re volving in a smaller orbit than the earth, is not seen by us because the hemisphere in which we live is always turned away from the counter-earth (the analogy of the moon which always turns the same side to us may have suggested this)."

"The idea that there might be another planet in our Solar System on an orbit that keeps it permanently behind the Sun dates back at least 2400 years to the Greek philosopher Philolaus. He postulated the existence of a ‘counter-Earth’ called Antichthon."

"Space boffs, UFO hunters and New Age spiritualists are convinced the Solar System's fabled ninth planet – dubbed "Planet X" – exists and it is just like Earth.

But we cannot see it as it is locked in exactly the same orbit as Earth – 180 degrees around, on the other side of the Sun.

The mind-blowing theory dates back to an ancient Greek wiseman called Philolaus – who called the planet "Counter Earth"."
