The Sun seems to move against the background stars as seen from the orbiting Earth. The ecliptic is the path the Sun appears to trace through the stars. The Earth completes its orbit and the Sun traces its entire path in a little over 365 days.

Unknown extension tag "indicator"{{#invoke:Category handler|main}} The ecliptic is the apparent path of the Sun on the celestial sphere, and is the basis for the ecliptic coordinate system. It also refers to the plane of this path, which is coplanar with both the orbit of the Earth around the Sun and the apparent orbit of the Sun around the Earth.<ref name="AA2010"> {{#invoke:citation/CS1|citation |CitationClass=book }}</ref> The path of the Sun is not normally noticeable from the Earth's surface because the Earth rotates, carrying the observer through the cycles of sunrise and sunset, obscuring the apparent motion of the Sun with respect to the stars.
