If the plane of the epicycle were tilted slightly relative to the plane of the deferent, then the retrograde motion would sometimes loop on one side of the deferent, and sometimes on the other side, mimicking the actual observed behavior much better than the hippopede idea of Eudoxus. discussed last week.

Earth is so close to the Sun and planets (compared to the immensely far stars) that we observe their Retrogression: (or Retrograde Motion) - Movement of a weather system in a direction opposite to that of the basic flow in which it is embedded, usually referring This science fair project idea recreates the movement of planetary bodies in order to learn why they sometimes appear to move backwards. 22 Jun 2018 All of the planets in our solar system exhibit this "retrograde motion" at one time or another.

from Tunç Tezel. 2 years ago. 2018 was a favourable year for observing Mars. Thanks to the perihelic opposition on 27th July, the distance to Mars shrunk to 58 million km. In fact, this was the closest Mars got since 2003. Neptune will enter retrograde motion, halting its usual eastward movement through the constellations, and turning to move westwards instead. This reversal of direction is a phenomenon that all the solar system's outer planets periodically undergo, a few months before they reach opposition.

This apparent retrograde motion is caused by the Earth traveling past a slower-moving outer planet (Jupiter, Saturn, Uranus, Neptune and Pluto) or when the Earth is itself passed by a faster-moving inner planet (Mercury, Venus or Mars).
