This makes the equator 0.16% longer than a meridian (a great circle passing through the two poles). The added velocity reduces the fuel needed to launch spacecraft eastward (in the direction of Earth's rotation) to orbit, while simultaneously avoiding costly maneuvers to flatten inclination during missions such as the Apollo moon landings. 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. 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.

[2], Sites near the equator, such as the Guiana Space Centre in Kourou, French Guiana, are good locations for spaceports as they have a fastest rotational speed of any latitude, 460 m (1,509 ft)/sec. 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. Near the equator, this means the variation in strength of solar radiation is different relative to the time of year than it is at higher latitudes: Maximum solar radiation is received during the equinoxes, when a place at the equator is under the subsolar point at high noon, and the intermediate seasons of spring and autumn occur at higher latitudes, and the minimum occurs during both solstices, when either pole is tilted towards or away from the sun, resulting in either summer or winter in both hemispheres. Rainfall is very high away from cold ocean current upwelling zones, from 2,500 to 3,500 mm (100 to 140 in) per year. The geographical mile is defined as one arc-minute of the equator, so it has different values depending on which radius is assumed. It is one of the lines known as a line of latitude, or circle of latitude. How to use equator in a sentence. The International Association of Geodesy (IAG) and the International Astronomical Union (IAU) have chosen to use an equatorial radius of 6,378.1366 km (3,963.1903 mi) (codified as the IAU 2009 value).

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. It is identified as the latitude that falls at the point that is equidistant from the North Pole and the South Pole. The north pole is north of the Equator and the south pole is south of the Equator. For both GRS 80 and WGS 84, this results in a length for the equator of 40,075.0167 km (24,901.4609 mi). [5] This equatorial radius is also in the 2003 and 2010 IERS Conventions.

The latitude of the equator is defined as zero degrees. 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). 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 halfway between the North and South Poles, and divides the Earth into the Northern and Southern Hemispheres. Southern latitudes can also be expressed as negative number where -90° is at the South Pole. the equator: an imaginary circle around the middle of the Earth that is the same distance from the North Pole and the South Pole. [citation needed]. If you could cut the Earth in half, the Equator would be the line where both hemispheres meet. 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. Despite high year-round sea level temperatures, some higher altitudes such as the Andes and Mount Kilimanjaro have glaciers. The Atlantic Ocean (at the Gulf of Guinea and the Perigoso Canal) 2.

At the equator there is a tropical climate, and travelling south of the equator it gets cooler again before reaching the Antarctic. The Equator is the parallel line located at 0°00’00”. 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 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.
