The plane of Earth's equator, when projected outwards to the celestial sphere, defines the celestial equator. The equator is a line which is not real drawn around a sphere or planet, such as the Earth. The name "equator" is Latin for "even-maker"; at equator the day and night are exactly the same length around the year. … In geography, latitude is the distance on the earth’s surface, north or south of the Equator, expressed in angular measurements from 0° at the Equator to 90° (North or South). It is identified as the latitude that falls at the point that is equidistant from the North Pole and the South Pole. Equator definition, the great circle on a sphere or heavenly body whose plane is perpendicular to the axis, equidistant everywhere from the two poles of the sphere or heavenly body. The Pacific Ocean (between Aranuka and Nonouti atolls in Kiribati) 3. The Equator is an imaginary line around the middle of the Earth. The name is derived from medieval Latin word aequator, in the phrase circulus aequator diei et noctis, meaning 'circle equalizing day and night', from the Latin word aequare meaning 'make equal'.[1]. The latitude of the Earth's equator is, by definition, 0° (zero degrees) of arc. The Equator is the parallel line located at 0°00’00”. For example, the Empire State Building is located at 40.7 degrees north (latitude), 74 degrees west (longitude). Nevertheless, temperatures are high year round due to the earth's axial tilt of 23.5° not being enough to create a low minimum midday declination to sufficiently weaken the sun's rays even during the solstices. Learner's definition of EQUATOR. The city of Quito, Ecuador, lies very close to the equator. If you could cut the Earth in half, the Equator would be the line where both hemispheres meet. Latitude is the measurement of distance north or south of the Equator.It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. The geographical mile is defined as one arc-minute of the equator, so it has different values depending on which radius is assumed. Changes in Earth axis can also be observed in the geographic layout of volcanic island chains, which are created by shifting hot spots under the Earth's crust as the axis and crust move. The distance around the Earth at the Equator, its circumference, is 40,075 kilometers (24,901 miles). Southern latitudes can also be expressed as negative number where -90° is at the South Pole. The latitude of the equator is defined as zero degrees. A place's absolute location is its exact place on Earth, often given in terms of latitude and longitude. By definition, the latitude of the Earth’s equator is 0 degrees, while the Tropic of Cancer and the Tropic of Capricorn each lie at 23.5 degrees latitude. Indonesia is the country straddling the greatest length of the equatorial line across both land and sea.

Look it up now! 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. Experts can attempt the prime meridian or the tropic of breast cancer. The equator is an imaginary line that runs from east to west on Earth's surface and is exactly halfway between the north and south poles (the northernmost and southernmost points on the Earth). The north pole is north of the Equator and the south pole is south of the Equator. Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator. It is identified as the latitude that falls at the point that is equidistant from the North Pole and the South Pole. [citation needed] Milder line-crossing ceremonies, typically featuring King Neptune, are also held for passengers' entertainment on some civilian ocean liners and cruise ships. An imaginary line around the Earth midway between the poles. The equator is one of the five notable circles of latitude on Earth; the other four are both polar circles (the Arctic Circle and the Antarctic Circle) and both tropical circles (the Tropic of Cancer and the Tropic of Capricorn). Equator definition is - the great circle of the celestial sphere whose plane is perpendicular to the axis of the earth. Latitude has three different kinds. Equinox definition, the time when the sun crosses the plane of the earth's equator, making night and day of approximately equal length all over the earth and occurring about March 21 (vernal equinox, or spring equinox ) and September 22 (autumnal equinox ). This is slightly above the snow line and is the only place on the equator where snow lies on the ground. The name "equator" is Latin for "even-maker"; at equator the day and night are exactly the same length around the year. The latitude of the equator is defined as zero degrees. The Equator’s covers a distance on the Earth’s surface approximately 24,901 miles long. At the equinoxes, the Earth's axis is perpendicular to the sun rather than tilted toward or away, meaning that day and night are both about 12 hours long across the whole of the Earth. Equator may also refer to: Lines of latitude run parallel to the Equator. The equator is the only line of latitude which is also a great circle—that is, one whose plane passes through the center of the globe. The equator is the only line of latitude which is also a great circle—that is, one whose plane passes through the center of the globe. Light rays from the Sun's center are perpendicular to Earth's surface at the point of solar noon on the equator. The equator is defined as an imaginary line drawn on the Earth and spaced equally between the North and South Pole. ... equator: Meaning and Definition of. What is latitude? Technically, the equator is not fixed to the true equatorial plane because the plane drifts with the polar motion of the earth for about 30 feet throughout the year. —. The Earth is widest at its Equator. Pronunciation: (i-kwā'tur), — n. When the Sun is directly above the Earth's Equator (on the equinoxes of approximately March 20 and September 23), sunlight shines perpendicular to the Earth's axis of rotation, and all latitudes have a 12-hour day and 12-hour night. The terms summer, autumn, winter and spring do not generally apply. The length of daylight (sunrise to sunset) is almost constant throughout the year; it is about 14 minutes longer than nighttime due to atmospheric refraction and the fact that sunrise begins (or sunset ends) as the upper limb, not the center, of the Sun's disk contacts the horizon.

An equator is an imaginary line around the middle of a planet or other celestial body.It is halfway between the North Pole and the South Pole, at 0 degrees latitude.An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere. Seasons result from the tilt of the Earth's axis compared to the plane of its revolution around the Sun. The celestial equator refers to the circle that results when one imaginarily projects the terrestrial equator against the background of the fixed stars. Anything lying north of the Equator is in the Northern Hemisphere and is labelled °N. 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. 4. celestial equator.
