Mercury stations retrograde on January 17, 2081 at 13° Aquarius, and direct on February 7 at 28° Capricorn — 21 days. From the Earth, Mercury seems to back up against the stars as we overtake it, as a car passed on the highway seems to slide backward. Astrology holds it a time for crossed wires and delays. Computed from JPL's approximate orbits; the stations agree with an almanac's to within minutes.
