1. EQUATORnoun

   On the earth, or equinoctial in the heavens, is a great circle, whose poles are the poles of the world. It divides the globe into two equal parts, the northern and southern hemispheres. It passes through the east and west points of the horizon; and at the meridian is raised as much above the horizon as is the complement of the latitude of the place. Whenever the sun comes to this circle, it makes equal days and nights all round the globe, because he then rises due east and sets due west, which he doth at no other time of the year. John Harris

   Etymology: æquator, Latin.

   By reason of the convexity of the earth, the eye of man, under the equator, cannot discover both the poles; neither would the eye, under the poles, discover the sun in the equator. Thomas Browne, Vulgar Errours, b. vi. c. 5.

   On the other side the equator there is much land still remaining undiscovered. John Ray, on the Creation.

   Rocks rich in gems, and mountains big with mines,
   That on the high equator ridgy rise,
   Whence many a bursting stream auriferous plays. James Thomson.

1. Equator

   The equator is a circle of latitude that divides a spheroid, such as Earth, into the northern and southern hemispheres. On Earth, it is an imaginary line located at 0 degrees latitude, about 40,075 km (24,901 mi) in circumference, halfway between the North and South poles. The term can also be used for any other celestial body that is roughly spherical. In spatial (3D) geometry, as applied in astronomy, the equator of a rotating spheroid (such as a planet) is the parallel (circle of latitude) at which latitude is defined to be 0°. It is an imaginary line on the spheroid, equidistant from its poles, dividing it into northern and southern hemispheres. In other words, it is the intersection of the spheroid with the plane perpendicular to its axis of rotation and midway between its geographical poles. On and near the equator (on Earth), noontime sunlight appears almost directly overhead (no more than about 23° from the zenith) every day, year-round. Consequently, the equator has a rather stable daytime temperature throughout the year. On the equinoxes (approximately March 20 and September 23) the subsolar point crosses Earth's equator at a shallow angle, sunlight shines perpendicular to Earth's axis of rotation, and all latitudes have nearly a 12-hour day and 12-hour night.

1. Equatornoun

   the imaginary great circle on the earth's surface, everywhere equally distant from the two poles, and dividing the earth's surface into two hemispheres

2. Equatornoun

   the great circle of the celestial sphere, coincident with the plane of the earth's equator; -- so called because when the sun is in it, the days and nights are of equal length; hence called also the equinoctial, and on maps, globes, etc., the equinoctial line

3. Etymology: [L. aequator one who equalizes: cf. F. quateur equator. See Equate.]

1. Equator

   An equator is the intersection of a sphere's surface with the plane perpendicular to the sphere's axis of rotation and midway between the poles. The Equator usually refers to the Earth's equator: an imaginary line on the Earth's surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. Other planets and astronomical bodies have equators similarly defined. The Equator is about 40,075 kilometres long; 78.7% is across water and 21.3% is over land.

1. equator

   Called also the equinoctial line, or simply the line, being an imaginary circle round the earth, dividing the globe into two equal parts, and equally distant from both poles. Extended to the heavens, it forms a circle called the celestial equator, which in like manner divides the heavens into two equal parts, the northern and southern hemispheres.
