Every few months, social media fills with warnings: “Mercury is retrograde – don’t sign anything!” But what is actually happening, and should you really cancel your plans?
What happens in the sky
Mercury is the planet closest to the Sun and orbits much faster than Earth. About three or four times a year, because of the difference in speed between Earth and Mercury, the planet appears to move backward across the sky for roughly three weeks. It is an optical effect – similar to the way a slower train seems to move backward when your train overtakes it.
Astronomers call this “apparent retrograde motion”. Mercury does not actually change direction.
What astrologers say it means
In astrology, Mercury rules communication, travel, technology, contracts and thinking. During its retrograde periods, astrologers traditionally link it with:
- misunderstandings and missed messages,
- travel delays and lost items,
- technology glitches,
- people from the past reappearing.
Of course, these things happen all year round. Mercury retrograde simply gives astrology fans a reason to pay closer attention.
