Brief Facts About Mercury in Astrology

Mercury is the closest planet to the Sun and the smallest in the solar system, being the size of the Atlantic Ocean. It's a rocky world that doesn't have oxygen or water. Throughout its 87.97 Earth-day orbit, when viewed from Earth, Mercury appears to sway back and forth (known in Astrology as retrograde motion). 

Mercury in Mythology

In Roman mythology, Mercury was the god of business. The words "merchant" and "business" derive from the Latin root of his name. To the Greeks, Mercury was represented by Hermes, the god of movement, transference and exchange. Hermes guided the souls of the dead to the underworld and was a messenger of the gods.

Son of Zeus and the nymph Maia, Hermes' divine nature was established as early as the day of his birth. Before noon that same day, Hermes invented the lyre and, at the end of the day, had stolen the cattle from his half-brother, Apollo. The latter was very angry but his father Zeus was delighted with Hermes' intelligence and soon promoted him, making him his butler.

Find out more about the symbolism of each of the planets in Astrology, by selecting the planet to consult below:

  • The Sun - Identity, Individuality, the Father
  • The Moon - Instincts, Subconscious, Mother
  • Mercury - Mentality, Communication

Each planet dominates a specific aspect of our life. Your Sun Sign, that is, the sign of the Zodiac where the Sun was positioned at the time we were born, governs the most intimate facet of our "I". However, the remaining planets in the Solar System also contribute to the characterization of our Astrological Personality. For example, if Mercury, the planet that governs communication, was positioned in Leo when you were born, your communication style is likely to be passionate and enthusiastic - characteristics traditionally attributed to this sign.
