What Does Retrograde Mean
Retrograde is an apparent backward motion of a planet as seen from Earth. It happens when Earth passes a slower outer planet in its orbit. This optical illusion affects the planet's position in the sky.
When Does Retrograde Occur
Each planet goes retrograde at different intervals. Mercury retrograde happens three to four times a year. Mars retrograde occurs roughly every two years. Outer planets like Jupiter and Saturn retrograde annually for several months. The dates vary each year based on planetary cycles.
How Long Does Retrograde Last
Mercury retrograde typically lasts about three weeks. Mars retrograde can last around two months. Outer planet retrogrades often span four to six months. The period includes a shadow phase before and after the main retrograde window. For exact dates, check an astronomical calendar or site like timeanddate.com retrograde schedule.
