The Zodiac, in astronomy and astronomy, is a celestial band that stretches 9 ° across the ecliptic, the plane of the earth and the orbit of the visible sun. The orbits of the moon and of the main planet are also inside the stars. The 12-pointed star signals are considered 1/12 (or 30 °) of their larger circle. These signs no longer correspond to the constellations in which the sun actually rises. The stars are not equal in size and shape, and the sun always passes through one star (Ophiuchus) that can be considered a member of the stars.
Because most galaxies where ecliptic passes represent animals, the ancient Greeks called their place zōdiakos kyklos, “animal circle,” or ta zōdia, “small animals.” The size and number of astronomical stars varied in ancient times and were fixed only by astronomy. The list below gives the constellations, and the solar eclipses pass through them while their boundaries were adjusted. These days are still used for astrological signs, although the consideration of equinoxes has moved the stars to the east; e.g., on January 1 the direction of the sun is now in Sagittarius instead of Capricornus. The history of the symbols is unknown; they seem to have first appeared in medieval Greek manuscripts.
