1 janv. 200 - Orbital motion of Mars. Proposed order of planets.
Description:
In Roman Egypt, Claudius Ptolemaeus, also known as Ptolemy, attempted to figure out the orbital motion of Mars. He proposed the new order of the planets, by increasing distance: the Moon, Mercury, Venus, Sun, Mars, Jupiter, Saturn, and the fixed stars. Ptolemy's planetary system and his collective work on astronomy became the authoritative treatise for the next 14 centuries.Ajouté au bande de temps:
