A planet never moves backwards. But Earth and the planet orbit the Sun at different speeds: when one overtakes the other, the planet, seen from here, seems to slow down, stop, back up for a few weeks, then move forward again. It's a perspective effect, regular and predictable centuries in advance.
In astrology, a retrograde planet invites you to go back over what it stands for: for Mercury, the planet of communication, it's a time to reread, review and repair rather than start something new. It's a symbolic reading: nothing proves that Mercury retrograde makes devices break down, but the advice to reread before you hit send always helps.
The shadow, for Mercury, Venus and Mars: the planet covers the same degrees three times, moving forward, backward, then forward again. Some astrologers already see the retrograde's theme in the shadow: a build-up before, a wrap-up after.
A station is the moment the planet seems to stop in the sky, before backing up or moving forward again. We look for it day by day, then refine it to the second with the Swiss Ephemeris (NASA ephemerides); the dates are checked against a second, independent calculation (Skyfield).
