Antarctica sits on every line of longitude because the South Pole is on the continent. Theoretically, Antarctica would be located in all time zones; however, areas south of the Antarctic Circle experience extreme day-night cycles near the times of the June and December solstices, making it difficult to determine which time zone would be appropriate.
A mean solar day (what we normally measure as a "day") is the average time between local solar noons ("average" since this varies slightly over a year). Earth makes one rotation around its axis each sidereal day; during that time it moves a short distance (about 1°) along its orbit around the Sun.
Antarctica Day is an international holiday recognizing the anniversary of the signing of the Antarctic Treaty in 1959. It is celebrated on December 1 each year. It is celebrated on December 1 each year.
The highest temperature ever recorded at the Amundsen–Scott South Pole Station was −12.3 °C (9.9 °F) on Christmas Day, 2011, [36] and the lowest was −82.8 °C (−117.0 °F) on 23 June 1982 [37] [38] [39] (for comparison, the lowest temperature directly recorded anywhere on earth was −89.2 °C (−128.6 °F) at Vostok Station on 21 ...
Midwinter Day, or Midwinter, is an annual celebration held across Antarctica on the day of the southern winter solstice (June 20 or 21). It is the continent's primary cultural holiday and, along with Antarctica Day , is one of two principal Antarctic holidays. [ 1 ]
In Argentina, the Day of the Argentine Antarctic, or Argentine Antarctic Sovereignty Day (Spanish: Día de la Antártida Argentina, lit. 'day of the Argentine Antarctic'), [1] is commemorated annually on 22 February. It commemorates what Argentina says was the first permanent settlement, in 1904, in an area later claimed as an integral part of ...
Polar night is a phenomenon that occurs in the northernmost and southernmost regions of Earth when the Sun remains below the horizon for more than 24 hours. This only occurs inside the polar circles. [1] The opposite phenomenon, polar day or midnight sun, occurs when the Sun remains above the horizon for more than 24 hours.
It is the lunar equivalent of the division between night and day on the Earth spheroid, although the Moon's much lower rate of rotation [7] means it takes longer for it to pass across the surface. At the equator, it moves at 15.4 kilometres per hour (9.6 mph), as fast as an athletic human can run on earth.
