.Such places also have a theoretical constant 12 hours of day and night throughout the year, though in practice there are variations of a few minutes due to the effects of atmospheric refraction and because sunrise and sunset are measured from the time the edge of the Sun's disc is on the horizon, rather than its centre.^ Days gradually become longer than 12 hours, nights shorter.

Spacecraft launched in this manner must launch to the east to use this effect.
For high precision work, the Equator is not quite as fixed as the above discussion implies. The true equatorial plane must always be perpendicular to the Earth's spin axis. Although this axis is relatively stable, its position wanders in an approximately 9 metres (30 ft) radius circular motion each year. Thus, the true equator moves slightly, but this effect is only relevant to detailed scientific studies.

## Exact length of the Equator

The Equator is modeled exactly in two widely used standards as a circle of radius an integer number of metres. .In 1976 the IAU standardized this radius as 6,378,140 metres (20,925,656 ft), subsequently refined by the IUGG to 6,378,137 metres (20,925,646 ft) and adopted in WGS-84, though the yet more recent IAU-2000 has retained the old IAU-1976 value.^ Promising higher-dimensional supergravity theory developed in the 1970s, subsequently ignored, and more recently shown to be an important part of string theory.

In either case, the length of the Equator is by definition exactly 2π times the given standard, which to the nearest millimeter is 40,075,016.686 metres (131,479,713.54 ft) in WGS-84 and 40,075,035.535 metres (131,479,775.38 ft) in IAU-1976 and IAU-2000.[1]
The geographical mile is defined as one arc minute of the Equator, and therefore has different values depending on which standard equator is used, namely 1,855.3248 metres (6,087.024 ft) or 1,855.3257 metres (6,087.027 ft) for respectively WGS-84 and IAU-2000, a difference of nearly a millimeter.
The earth is standardly modeled as a sphere flattened 0.336% along its axis. .This results in the Equator being 0.16% longer than a meridian (as a great circle passing through the two poles).^ The great circle on the surface of a body formed by the intersection of the surface with the plane passing through the center of the body perpendicular to the axis of rotation.

^ [H76] (c) Either of the two points on the celestial sphere at which the ecliptic intersects the celestial equator; also the time at which the Sun passes through either of these intersection points; i.e., when the apparent longitude (see Apparent Place; Longitude, Celestial) of the Sun is 0° or 180°.

.The IUGG standard meridian is, to the nearest millimeter, 40,007,862.917 metres (131,259,392.77 ft), one arc minute of which is 1,852.216 metres (6,076.82 ft), explaining the SI standardization of the nautical mile as 1,852 metres (6,076 ft), more than 3 metres (10 ft) short of the geographical mile.^ Pauli's exclusion principle says that there could not be more than one electron in each quantum state.

## Notes

1. ^ Although millimeter precision can be important up to the scale of a mile, it has negligible physical significance at the scale of a geographic feature such as the Equator. From a computational standpoint, however, millimeter precision or better can be valuable for maintaining consistent results when used in programs for surveying and other applications that require precise measurements. As an overly simple example, if a program were to convert back and forth between the radius and the circumference of the earth sufficiently often while maintaining precision only to a meter each time, errors might accumulate until they became noticeable.

### From LoveToKnow 1911

'EQUATOR (Late Lat. aequator, from aequare to make equal), in geography, that great circle of the earth, equidistant from the two poles, which divides the northern from the southern hemisphere and lies in a plane perpendicular to the axis of the earth; this is termed the "geographical" or "terrestrial equator." In astronomy, the "celestial equator" is the name given to the great circle in which the plane of the terrestrial equator intersects the celestial sphere; it is consequently equidistant from the celestial poles. .The "magnetic equator" is an imaginary line encircling the earth, along which the vertical component of the earth's magnetic force is zero; it nearly coincides with the terrestrial equator.^ The equator is an imaginary line that circles the center of the earth.

 Singular Equator Plural -

1. The Earth’s equator.

Map of Earth showing the equator and other major lines of latitude

The equator is a line which is not real drawn around a sphere or planet, such as the Earth. It is one of the lines known as a line of latitude, or circle of latitude. The name "equator" is Latin language and means "even-maker"; at equator the day and night are exactly the same length around the year.

The equator is halfway between the North Pole and the South Pole. There, the surface of the planet is parallel to the axis of rotation. The equator divides the surface into the Northern Hemisphere and the Southern Hemisphere.

## Climate

Unlike the Northern Hemisphere and the Southern Hemisphere, countries around the equator do not experience the four seasons, and the climate is usually very humid.
