The Antichthon (Counter-Earth or Gloria) is a hypothetical body of the Solar system hypothesized by the pre-Socratic Greek philosopher Philolaus (c. 470 – c. 385 BC) to support his non-geocentriccosmology, in which all objects in the universe revolve around an unseen "Central Fire" (distinct from the Sun which also revolves around it).
