Mercury is a planet associated astrologically with communication, thought, learning, perception, language, reasoning, and information exchange. It is commonly grouped astrologically as a Personal Planet. Astronomically, Mercury is also an Inner Planet because it lies inside the asteroid belt and an Inferior Planet because its orbit lies closer to the Sun than Earth’s.
