Mercury (☿) — Communication, Mind, Exchange

Mercury is the planet of intellect, communication, and exchange, with its domiciles in Gemini and Virgo and its exaltation in Virgo. As the fastest-moving visible planet, it governs all forms of mediation: language, commerce, travel, and the nervous system's transmission of signals. Astrodienst identifies Mercury as neither masculine nor feminine but chameleon-like, taking on the character of whatever planet it aspects most closely. Cafe Astrology notes that Mercury's retrograde periods — when the planet appears to reverse its course through the zodiac — have become the most popularly recognized astrological phenomenon, reflecting the sign's governance over the mechanisms of daily connection.
