Answer:
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. Traditionally, this region is divided into 12 signs of 30° longitude, each of which approximates the Sun's motion in one month.
Explanation:
The sun's motion through the constellations
Its motion is entirely an illusion, caused by Earth's own motion around our star. Over the course of a year, the sun appears to be in front of, or “in”, different constellations.
