The Pythagoreans, in the 6th and 5th centuries BC appear to have developed their own independent planetary theory, which consisted of the Earth, Sun, Moon, and planets revolving around a "Central Fire" at the center of the Universe.
Pengikut Pythagoras pada abad ke-6 dan 5 SM tampaknya sudah mengembangkan teori keplanetannya sendiri yang terdiri dari Bumi, Matahari, Bulan, dan planet-planet mengelilingi "Api Tengah" di pusat Alam Semesta.
