Retrograde refers to something that is opposite the usual order, inverted or reversed as well as a movement that goes backward.
3 - 4 times a year the planet Mercury slows down and appears to stop and move backward (retrograde). However this is an optical illusion. There is still forward movement but as it recedes it appears to go backward.
Mercury Retrograde was created on 2008-06-03.
