equinox Audio Help (ē'kwə-nŏks') Pronunciation Key

Either of the two points on the celestial sphere where the ecliptic (the apparent path of the Sun) crosses the celestial equator. ◇ The point at which the Sun's path crosses the celestial equator moving from south to north is called the vernal equinox. The vernal equinox marks the zero point in both the equatorial and ecliptic coordinate systems; horizontal angular distances (right ascension in the equatorial system and celestial longitude in the ecliptic system) are measured eastward from this point. The vernal equinox is also known as the first point of Aries because when first devised some 2,000 years ago this point occurred at the beginning of Aries in the zodiac. Because of the westward precession of the equinoxes, the vernal equinox is now located at the beginning of Pisces. ◇ The point at which the Sun's path crosses the celestial equator moving from north to south is called the autumnal equinox.
Either of the two corresponding moments of the year when the Sun is directly above the Earth's equator. The vernal equinox occurs on March 20 or 21 and the autumnal equinox on September 22 or 23, marking the beginning of spring and autumn, respectively, in the Northern Hemisphere (and the reverse in the Southern Hemisphere). The days on which an equinox falls have about equal periods of sunlight and darkness. Compare solstice.

1. Pertaining to an equinox, or the equinoxes, or to the time of equal day and night; as, the equinoctial line.

2. Pertaining to the regions or climate of the equinoctial line or equator; in or near that line; as, equinoctial heat; an equinoctial sun.

3. Pertaining to the time when the sun enters the equinoctial points; as, an equinoctial gale or storm, that is, one happening at or near the time of the equinox, in any part of the world.

Equinoctial colure (Astron.), the meridian passing through the equinoctial points.

Equinoctial line (Astron.), the celestial equator; -- so called because when the sun is on it, the nights and days are of equal length in all parts of the world. See Equator.

Thrice the equinoctial line He circled. --Milton.

Equinoctial points (Astron.), the two points where the celestial and ecliptic intersect each other; the one being in the first point of Aries, the other in the first point of Libra.

Equinoctial time (Astron.) reckoned in any year from the instant when the mean sun is at the mean vernal equinoctial point.
