It's Baaack! What's Mercury Retrograde + What Does It Mean For YOU?--3-4x a year, everyone's favorite havoc-wreaking planet slows down in its orbit+ appears to move backward.From an astrological standpoint, Mercury is the ruler of communication, honesty, clarity+ even travel,+ astrologers find a correlation between retrograde motion+ sheer bad luck, bc the planet's going against its natural movement. But in reality, it's not--what's different is our perception of how the Earth is moving.
