Counter-Earth
Hypothetical planet on the other side of the Sun from Earth
The Counter-Earth is a hypothetical body of the Solar System that orbits on the other side of the Solar System from Earth. A Counter-Earth or Antichthon was hypothesized by the pre-Socratic Greek philosopher Philolaus to support his non-geocentric cosmology, in which all objects in the universe revolve around a "Central Fire".
