♈♉♊♋♌♍♎♏♐♑♒♓ The zodiac is the belt or band of constellations through which the Sun, Moon, and planets move on their journey across the sky. Astrologers noted these constellations and so attached a particular significance to them. Over time they developed the systems of twelve signs of the zodiac,
based on twelve of the constellations through which the sun passes throughout the year, those constellations that are "Enlightened by the mind".
