Of or relating to the ecliptic or an eclipse.
ETYM Cf. French écliptique, Latin linea ecliptica, Greek ekleiptikos, prop. adj, of an eclipse, because in this circle eclipses of the sun and moon take place. Related to Ecliptic.
The great circle representing the apparent annual path of the sun; the plane of the Earth's orbit around the sun; makes an angle of about 23 degrees with the equator.
Imaginary circle which the sun follows from Earth perspective.
Astronomy, celestial great circle along which sun apparently travels.
Path, against the background of stars, that the Sun appears to follow each year as the Earth orbits the Sun. It can be thought of as the plane of the Earth's orbit projected on to the celestial sphere (imaginary sphere around the Earth).
The ecliptic is tilted at about 23.5ş with respect to the celestial equator, a result of the tilt of the Earth's axis relative to the plane of its orbit around the Sun.
