Mercury moves quickly as it orbits the Sun. Astrologically, Mercury thinks fast, it is the ruler of communication and logic in a variety of forms. Although the planet Mercury is the planet closest to the Sun, Mercury is not the hottest planet because it does not have an atmosphere. This also seems to go with the light quickness we associate with Mercury’s impact as it moves around the zodiac. From the perspective of Earth, Mercury is never more than 28 degrees away from the Sun. This is one reason we think of Mercury as the Messenger between realms, the one that can bring messages to the gods.

Mercury is not associated with the masculine or the feminine. It is neutral and can be either yin or yang depending on its sign placement and the planets that it’s with. Mercury was classified as Cold and Dry by the ancients. Mercury was associated with the Nervous temperament and Air.
