The ecliptic runs along the middle of the Zodiac. Learn how it all works. ... Of the imaginary coordinate lines that astronomers and navigators use in mapping the sky, perhaps the most important one is the ecliptic, the apparent path the Sun appears to take through the sky as a result of the Earth's revolution around it.
