  1. ecliptic(Noun)

    The apparent path of the Sun in the sky. More accurately, it is the intersection of the celestial sphere with the plane of the ecliptic, which is the geometric plane containing the mean orbit of the Earth around the Sun. So named because an eclipse can occur only when the Moon lies on this plane.

Freebase

  1. Ecliptic

    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. The path of the Sun is not normally noticeable from the Earth's surface because the Earth rotates, carrying the observer through the cycle of sunrise and sunset, obscuring the apparent motion of the Sun with respect to the stars.

The Nuttall Encyclopedia

  1. Ecliptic

    the name given to the circular path in the heavens round which the sun appears to move in the course of the year, an illusion caused by the earth's annual circuit round the sun, with its axis inclined at an angle to the equator of 23½ degrees; is the central line of the Zodiac (q. v.), so called because it was observed that eclipses occurred only when the earth was on or close upon this path.
