n an invisible line drawn around a spherical object at a right angle to the object's axis of rotation
(1) The central line of latitude, or parallel of reference "0°" which divides the Earth in half (2) In a spherical coordinate system, the great circle of a sphere which is perpendicular to the polar axis
Line around the ball, perpendicular to the midplane and the midline covering the entire circumference of the ball
An imaginary great circle around the earth, equidistant from the two poles, and dividing earths surface into the northern and southern hemisphere
The imaginary plane through the Earth which divides the northern and southern hemispheres See also: celestial equator
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
An imaginary circle around the Earth halfway between the North Pole and the South Pole; The largest circumference of the Earth
The Latitude reference point for the Lat/Long grid system Other positions of latitude are referenced as degrees of North Latitude if they are north of the equator and degrees of South Latitude if they are south of the equator Also see Latitude
This is the imagionary line that circles around the center of the earth and divides it into the northern hemisphere and the southern hemisphere Return to Regional Temperature Effects
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
the geographic circle at 0 degrees latitude on the Earth's surface It is an equal distance from the North and South Poles and divides the northern hemisphere from the southern hemisphere
The equator is an imaginary line around the middle of the earth at an equal distance from the North Pole and the South Pole. the equator an imaginary line drawn around the middle of the Earth that is exactly the same distance from the North Pole and the South Pole on/at/near the equator (aequator , from aequare ( EQUATE); because day and night are equal at the equator). Great circle around the Earth that is everywhere equidistant from the geographic poles and lies in a plane perpendicular to the Earth's axis. This geographic, or terrestrial, Equator divides the Earth into the Northern and Southern Hemispheres and forms the imaginary reference line on the Earth's surface from which latitude is reckoned (i.e., 0° latitude). In astronomy, the celestial equator is the great circle in which the plane of the terrestrial Equator intersects the celestial sphere; it is thus equidistant from the celestial poles. When the Sun lies in its plane, day and night are everywhere of equal length; this happens at the equinoxes
An imaginary circle around the earth, equally distant at all points from the North and South poles It divides the earth into two halves - the Northern and Southern Hemispheres
An imaginary circle around the Earth halfway between the North Pole and the South Pole; the largest circumference of the Earth
The geographic circle at 0 degrees latitude on the earth's surface It is equal distance from the North and South Poles and divides the Northern Hemisphere from the Southern
aequatio = [Latin] make equal The equator is a plane equally far from both geographical poles and divides the Earth into a northern and a southern part By extension, there is also an equator in the sky, which divides the sky into a northern and a southern part
The imaginary circle drawn around the middle of the Earth It runs east-west, marking latitude (side to side) It is found halfway between the north pole and the south pole
the equator is an imaginary line separating the northern and southern hemispheres The equator is exactly half way between the north and south poles It runs the circumference of the Earth and is the longest distance around the planet
The line around the ball perpendicular to the Midplane and the Midline covering the entire circumference of the ball
a circle dividing a sphere or other surface into two usually equal and symmetrical parts
{i} circle which is equally distant from both poles (on a heavenly body or sphere); imaginary circle dividing the Earth into northern and southern hemispheres
An imaginary circle around the Earth halfway between the North Pole and the South Pole; the largest circumference of the Earth It cuts the Earth into two equal parts, the northern and southern hemispheres Australia is south of the Equator
aequatio = [Latin] make equal The equator is equally far from both geographical poles and divides the Earth into a Northern and a Southern part By extension, there is also an equator in the sky, which divides the sky into a Northern and a Southern part
an imaginary line around the Earth forming the great circle that is equidistant from the north and south poles; "the equator is the boundary between the northern and southern hemispheres"
If you lived at the North Pole and look striaght up to the zenith, then all the stars in the sky move around the point directly above you Very near this point is a star 0 called the Pole Star All the stars in the sky seem to rotate around this point 90 degrees from the zenith is the horizon At the North Pole, the horizon also marks the position of the celestial equator If you live somewhere else on the Earth, then the Pole Star appears not at the zenith, but at an angle to the horizon equal to your latitude The celestial equator is now no longer at the horizon, but somewhere in the sky above the horizon If you live on the equator, then the Pole Star is now on the horizon, and the celestial equator is directly above you
The projection of Earth's equator onto the sky If you were standing on Earth's equator, the celestial equator would extend from eastern horizon, directly over your head (zenith), then to the western horizon Astronomers use an imaginary projection of Earth's latitude and longitude, called the celestial sphere, to locate planets, stars, star clusters, nebulae and galaxies
great circle that is a projection of the Earth's equator onto the sky Always intercepts horizon at exact East and exact West point Its meridian altitude = 90\deg -- observer's latitude We see one-half of its circle at a time (12 hours worth)
This is simply the projection of the Earth's equator, onto the celestial sphere The sphere is thus divided into Northern and Southern hemispheres in the same way as the Earth Declination is measured North or South of the celestial equator in degrees so that the celestial equator has a declination of 0° along its whole length See also celestial pole
the great circle of the celestial sphere all points of which are 90o from the poles It is the plane of the earth's equator projected onto the celestial sphere
The projection onto the celestial sphere of the Earth's equatorial plane, separating northern and southern hemispheres, and representing zero degrees of declination
The primary great circle of the celestial sphere in the equatorial system, everywhere 90° from the celestial poles; the intersection of the extended plane of the equator and the celestial sphere Also called equinoctial
The sky can be imagined as a sphere surrounding Earth A line projected out from the equator of Earth defines the celestial equator of the celestial sphere Standing on Earth's equator, the celestial equator would appear directly overhead
The imaginary line projected in the sky which is directly above the Earth's equator[?] At the equator, this line goes directly overhead, through the zenith[?] At either the north or south pole, this line forms a circle at the level of the horizon See also: celestial pole, ecliptic, meridian
The great circle of the celestial sphere that lies in the plane bisecting the band of the Milky Way, inclined at an angle of approximately 62° to the celestial equator. Also called galactic circle
The imaginary great circle on the earth's surface formed by the intersection of a plane passing through the earth's center perpendicular to the axis connecting the north and south magnetic poles
