e·clip·tic

(ĭ-klĭp′tĭk)
n.
1. The apparent path of the sun among the stars over the course of the year. The ecliptic is the great circle of the celestial sphere which is cut by the plane of the earth's orbit.
2. A great circle inscribed on a terrestrial globe inclined at an approximate angle of 23°26′ to the equator and representing the apparent motion of the sun in relation to the earth during a year.
3. The plane defined by the earth's solar orbit, with the sun at its center, that extends throughout the solar system.

[Middle English ecliptik, from Medieval Latin (līnea) eclīptica, ecliptic (line), from Latin eclīpticus, of an eclipse, from Greek ekleiptikos, from ekleipein, to fail to appear; see eclipse.]

e·clip·tic

(ĭ-klĭp′tĭk)
The great circle on the celestial sphere that is made by the plane containing Earth's orbit around the sun. The ecliptic traces the sun's apparent path in the sky in one year, as viewed from Earth.

"Try the test I told thee of, Sancho," said Don Quixote, "and don't mind any other, for thou knowest nothing about colures, lines, parallels, zodiacs, ecliptics, poles, solstices, equinoxes, planets, signs, bearings, the measures of which the celestial and terrestrial spheres are composed; if thou wert acquainted with all these things, or any portion of them, thou wouldst see clearly how many parallels we have cut, what signs we have seen, and what constellations we have left behind and are now leaving behind.
Here palms, alpacas, and volcanoes; sun's disks and stars; ecliptics, horns-of-plenty, and rich banners waving, are in luxuriant profusion stamped; so that the precious gold seems almost to derive an added preciousness and enhancing glories, by passing through those fancy mints, so Spanishly poetic.

There's no way there should be a correlation of structure with our motion of the earth around the sun--the plane of the earth around the sun--the ecliptic. That would say we are truly the center of the universe."
(17 & 18) EVENING: Watch as the fattening gibbous Moon hopscotches over Mars, first appearing some 5[degrees] right of the Red Planet and then 6[degrees] upper left, as it continues on its trek along the ecliptic.
However, because the Moon (and to a lesser extent the other planets) cause the true motion of the Earth to vary from a perfect ellipse, the equinox is now officially defined by the Sun's more regular ecliptic longitude rather than latitude.

From the direction of the constellation Lyra, it approached almost perpendicular to the ecliptic - an approximate plane of the solar system in which the planets and most asteroids orbit the sun - thereby avoiding any encounters with the eight planets during its inward journey.
