In astrology, the term Luminary refers specifically to the Sun and Moon, the two brightest celestial bodies as seen from Earth. They occupy a special place in Natal Chart interpretation and are commonly discussed alongside the Planets even though they are classified differently in astronomy. The Sun is associated with identity, vitality, purpose, and conscious self-expression, while the Moon is associated with emotional needs, instinctive responses, habits, memory, and security. Together, the Luminaries represent two foundational symbolic functions within Your Zodiacal Configuration. Their interpretation depends on their Signs, Aspects, and, when an exact birth time is available, House placements.
