Mercury in Retrograde…… 3 or 4 times a year, planet Mercury is said to go Retrograde, that is to say it moves in an opposite direction to planet earth. The same thing happens when our planet passes Mercury in our orbit around the sun. Mercury is just moving slower than earth, causing the illusion that it’s moving in Retrograde.
Retrograde……… An apparent change in the movement of the planet through the sky, it is not real in that the planet does not physically start moving backwards in it’s Orbit. It just appears to do so because of the relative positions of the planet and earth and how they are moving around the sun. The term Retrograde comes from the Latin word Retrogradus-which means backwards step. Retrograde is when a planet appears to go backwards.
