THERE ARE MANY TYPES ASTRONOMY- But In astronomy, the zodiac is the ring of constellations that lines the ecliptic, which is the apparent path of the Sun across the celestial sphere over the work of the year. The paths of the Moon plus planets also lie roughly within the ecliptic, plus so are also within the constellations of the zodiac. In astrology, the zodiac denotes those signs that divide the ecliptic into twelve equal zones of celestial longitude. As such, the zodiac is a celestial coordinate system, or more specifically an ecliptic coordinate system, taking the ecliptic as the origin of latitude, plus the position of the sun at vernal equinox as the origin of longitude.
It is known to have been in use by the Roman period, based on ideas inherited by Hellenistic astronomy from Babylonian astronomy of the Chaldean period , which, in turn, derived from an earlier system of lists of stars along the ecliptic. The construction of the zodiac is described in Ptolemy's Almagest .
Although the zodiac remains the basis of the ecliptic coordinate system in use in astronomy besides the equatorial one, the term plus the names of the twelve signs are today mostly associated with horoscopic astrology.
The term zodiac derives from Latin diacus, which in its turn comes from the Greek the diminutive of The name is motivated by the fact that half of the signs of the classical Greek zodiac are represented as animals.
