The Geographic South Pole is marked by the stake on the right NASA image showing Antarctica and the South Pole in 2005. The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the southernmost point on Earth and lies antipodally on the opposite side of Earth from the North Pole, at a distance of 20,004 km (12,430 miles) in all directions.
The Amundsen–Scott South Pole Station is a United States scientific research station at the South Pole of the Earth. It is the southernmost point under the jurisdiction (not sovereignty) of the United States. The station is located on the high plateau of Antarctica at 9,301 feet (2,835 m) above sea level. It is administered by the Office of ...
The position of the Sun in the sky is a function of both the time and the geographic location of observation on Earth 's surface. As Earth orbits the Sun over the course of a year, the Sun appears to move with respect to the fixed stars on the celestial sphere, along a circular path called the ecliptic. Earth's rotation about its axis causes ...
In a spherical coordinate system, a colatitude is the complementary angle of a given latitude, i.e. the difference between a right angle and the latitude. [1] In geography, Southern latitudes are defined to be negative, and as a result the colatitude is a non-negative quantity, ranging from zero at the North pole to 180° at the South pole.
The solar zenith angle is the zenith angle of the sun, i.e., the angle between the sun’s rays and the vertical direction. It is the complement to the solar altitude or solar elevation, which is the altitude angle or elevation angle between the sun’s rays and a horizontal plane. [1][2] At solar noon, the zenith angle is at a minimum and is ...
This article contains a list of notable circles of latitude on Earth.. Day length for any latitude, and sunrise and sunset times on any longitude, can be calculated for any date using, for example, the sunrise equation.
The pole of the upper hemisphere is called the zenith. The pole of the lower hemisphere is called the nadir. [5] The following are two independent horizontal angular coordinates: Altitude (alt.), sometimes referred to as elevation (el.) or apparent height, is the angle between the object and the observer's local horizon. For visible objects, it ...
Sun path, sometimes also called day arc, refers to the daily (sunrise to sunset) and seasonal arc -like path that the Sun appears to follow across the sky as the Earth rotates and orbits the Sun. The Sun's path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season.
