Mercury retrogrades for about three weeks, three to four times a year. No planet actually orbits backwards around the Sun, but they appear to retrograde because of their position in relationship to earth. Mercury retrogrades more frequently than any other planet, and its effects are often quite noticeable. For more information, see “Mercury Retrograde“.
