It feels like Mercury is always retrograding, in reality it only happens every few months. for instance 2023 will bestow upon us four retrogrades. We are now entering a new Mercury retrograde in Capricorn on December 29th that will take us through till January 18th. So buckle up and be patient with yourself and others, expect the unexpected.
Mercury retrograde explained by Lisa Stardust -
"Retrograde comes from the Latin word for "retrogradus," or "Backward step." During retrograde periods, planets appear to move "backwards."
We say appear, however, because this is an optical illusion. Mercury normally moves faster than the Earth around the sun, taking 88 days to complete an orbit whereas the Earth takes 365.
During retrograde periods, Mercury slows down. And as the blue planet overtakes Mercury, Mercury seems to be moving backwards. In fact, Earth is just moving faster than usual."
