WebbAstronomy is one of the oldest existing sciences, started when humans first looked at the night sky. The study of the sky is split into two main parts, observational astronomy and theoretical astronomy. Observational astronomy deals with the study of electromagnetic radiation from space. WebbThe path-line is the combined motion of the planet's orbit (deferent) around Earth and within the orbit itself (epicycle). In the Hipparchian, Ptolemaic, and Copernican systems of astronomy, the epicycle (from Ancient Greek ἐπίκυκλος (epíkuklos) 'upon the circle', meaning "circle moving on another circle") [1] was a geometric model ...
