![]() Hydra in the Early Bronze Age marked the celestial equator and was associated with Leo, which is shown standing on the serpent on the Dendera zodiac. Aquila, The Eagle, was possibly associated with the zodiac by virtue of its main star, Altair. In classical maps, it swallows the stream poured out of Aquarius' pitcher, but perhaps it formerly just swam in it. ![]() Furthermore, there are a number of constellations mythologically associated with the zodiacal ones : Piscis Austrinus, The Southern Fish, is attached to Aquarius. The MUL.APIN lists Orion, Perseus, Auriga, and Andromeda. Some "parazodiacal" constellations are also touched by the paths of the planets. The zodiacal signs are an abstraction from the physical constellations, and each represent exactly one twelfth of the full circle, or the longitude traversed by the Sun in about 30.4 days. Thus, Virgo takes up five times as much ecliptic longitude as Scorpius. The zodiacal signs are distinct from the constellations associated with them, not only because of their drifting apart due to the precession of equinoxes but also because the physical constellations take up varying widths of the ecliptic, so the sun is not in each constellation for the same amount of time. The order of the astrological signs is Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces." "In Western astrology, astrological signs are the twelve 30ยบ sectors of the ecliptic, starting at the vernal equinox (one of the intersections of the ecliptic with the celestial equator), also known as the First Point of Aries. The vector stencils library "Zodiac constellations" contains 12 star constellation charts. The example "Design elements - Northern constellations" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Astronomy solution from the Science and Education area of ConceptDraw Solution Park. The pole stars are special because they are approximately in line with the Earth's axis of rotation so they appear to stay in one place while the other stars rotate around them through the course of a night (or a year)." The Big Dipper (which has a wide variety of other names) is helpful for navigation in the northern hemisphere because it points to Polaris, the north star. Orion is among the most prominent and recognizable constellations. Constellations were identified without regard to distance to each star, but instead as if they were all dots on a dome. Different cultures have created different groupings of constellations based on differing interpretations of the more-or-less random patterns of dots in the sky. Constellations are prominent because their stars tend to be brighter than other nearby stars in the sky. "There are no markings on the night sky, though there exist many sky maps to aid stargazers in identifying constellations and other celestial objects. The vector stencils library "Northern constellations" contains 6 star constellation maps for drawing astronomical diagrams. The astronomical diagram example "Orion network" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Astronomy solution from the Science and Education area of ConceptDraw Solution Park.

The Orion Nebula is located south of Orion's belt." The three stars in the middle of the constellation form an asterism known as Orion's belt. Many of the other brighter stars in the constellation are hot, blue supergiant stars. Its brightest stars are Rigel (Beta Orionis) and Betelgeuse (Alpha Orionis), a blue-white and a red supergiant respectively. It was named after Orion, a hunter in Greek mythology. It is one of the most conspicuous and recognizable constellations in the night sky. "Orion is a prominent constellation located on the celestial equator and visible throughout the world.
