The ecliptic forms the center of the zodiac, a celestial belt about 20° wide in latitude through which the Sun, Moon, and planets always appear to move. [33] Traditionally, this region is divided into 12 signs of 30° longitude, each of which approximates the Sun's motion in one month. [ 34 ]
Navigational ephemeris tables record the geographic position of the first point of Aries as the reference for position of navigational stars. Due to the slow precession of the equinoxes, the zenith view (above a location) of constellations at a time of year from a given location have slowly moved west (by using solar epochs the drift is known).
Because it is a right-handed system, ecliptic longitude is measured positive eastwards in the fundamental plane (the ecliptic) from 0° to 360°. Because of axial precession , the ecliptic longitude of most "fixed stars" (referred to the equinox of date) increases by about 50.3 arcseconds per year, or 83.8 arcminutes per century, the speed of ...
In the description of the Babylonian zodiac given in the clay tablets known as the MUL.APIN, the constellation, now known as Aries, was the final station along the ecliptic. The MUL.APIN was a comprehensive table of the rising and settings of stars, which likely served as an agricultural calendar.
Draw an imaginary line from γ Crucis to α Crucis—the two stars at the extreme ends of the long axis of the cross—and follow this line through the sky. Either go four-and-a-half times the distance of the long axis in the direction the narrow end of the cross points, or join the two pointer stars with a line, divide this line in half, then ...
The term "zodiac" may also refer to the region of the celestial sphere encompassing the paths of the planets corresponding to the band of about 8 arc degrees above and below the ecliptic. The zodiac of a given planet is the band that contains the path of that particular body; e.g., the "zodiac of the Moon" is the band of 5° above and below the ...

Specifically, the division of the ecliptic in twelve equal sectors is a Babylonian conceptual construction. [7] This division of the ecliptic originated in the Babylonian "ideal calendar" found in the old compendium MUL.APIN and its combination with the Babylonian lunar calendar, [8] represented as the "path of the moon" in MUL.APIN. In a way ...
