equator,

imaginary great circle around the earth, everywhere equidistant from the two geographical poles and forming the base line from which latitude is reckoned. The equator, which measures c.24,902 mi (40,076 km), is designated as lat. 0°. It intersects N South America, central Africa, and Indonesia. The celestial equator is the projection of the plane of the earth's equator on the celestial sphere (see equatorial coordinate systemequatorial coordinate system,
the most commonly used astronomical coordinate system for indicating the positions of stars or other celestial objects on the celestial sphere. The celestial sphere is an imaginary sphere with the observer at its center.

equator

1. The great circle on the surface of a planet or star that lies in a plane – the equatorial plane – passing through the center of the body and perpendicular to the axis of rotation.
2. Short for celestial equator.

Equator

(religion, spiritualism, and occult)

The equator is the imaginary line drawn around Earth (and, by extension, other celestial bodies), separating it into northern and southern hemispheres. The celestial equator refers to the circle that results when one imaginarily projects the terrestrial equator against the background of the fixed stars.

(geodesy)
The great circle around the earth, equally distant from the North and South poles, which divides the earth into the Northern and Southern hemispheres; the line from which latitudes are reckoned.

equator

equator
The great circle on the surface of the earth whose plane is at right angles to the earth's axis of rotation. The equator lies in an east-west direction and divides the earth into Northern and Southern Hemispheres. It is normal to the polar axis and equidistant to the poles.
