Definition

The plane of Earth’s orbit and the Sun’s apparent annual path on the celestial sphere.

Why it matters

The ecliptic is the basic astronomical reference behind the zodiac. The Sun appears to move along it over the course of a year, and the Moon and planets stay relatively close to it in the sky.

Example

When astronomers give an object an ecliptic longitude, they are measuring its position along this reference circle.

Common confusion

The ecliptic is an astronomical reference, while astrological meanings assigned to zodiac positions are interpretive.
