Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year period, due to tidal forces resulting from the orbit of the Moon. [2] Consequently, the Antarctic Circle is currently drifting southwards at a speed of about 14.5 m (48 ft) per year.

Antarctic Circle, parallel, or line of latitude around Earth, at 66°30′ S. Because Earth’s axis is inclined about 23.5° from the vertical, this parallel marks the northern limit of the area within which, for one day or more each year, at the summer and winter solstices, the sun does not set

The Antarctic (or Antarctica) Circle is one of the five major circles or parallels of latitude that mark maps of the Earth. Shown on the image above with a dashed red line, this parallel of latitude sits at approximately 66.33° south of the Equator.

The continent of Antarctica is positioned in 90º 00' S latitude and 0º 00' E longitude respectively. It is located on the southern part of the Antarctic Circle. The total area is slightly smaller than 1°5 times to that of USA.

2021年3月19日 · Antarctic Circle . This parallel of latitude is currently at 66° 33′ 46″ south of the Equator (or -66.5628°). Like the Arctic, the position of the Antarctic Circles is not fixed, as their exact location depends on the Earth's axial tilt, which fluctuates within a margin of 2° over a 40,000 year period, mainly due to tidal forces ...

The Antarctic Circle is one of the five major circles of latitude that mark maps of the Earth. It is the parallel of latitude at 66° 33′ 39″ south of the Equator, crossing mostly the Southern Ocean. In the Antarctic Circle, all places have twenty-four hours of daylight on the Summer Solstice in …

2018年4月13日 · The Antarctic Circle is located at approximately 66.5 degrees south latitude, or 66.5 degrees south of the equator. This line, or circle, of latitude marks the start of the southern area known as the Antarctic. The circle consists of only one continent, Antarctica.

The Antarctic Circle is one of the five major circles (or parallels) of latitude that mark maps of the Earth. Latitude: -66° 33' 59.99" S Longitude: 0° 00' 0.00" E

2024年6月22日 · While the Antarctic Circle is located at approximately 66 degrees south latitude, its counterpart, the Arctic Circle, is situated at 66 degrees north latitude. Both circles mark the boundaries of the polar regions and play important roles in defining the unique climatic characteristics of these regions.

Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle (one of the five major circles of latitude that mark maps of the world), Antarctica is surrounded by the Southern Ocean. [note 2] Rivers exist in Antarctica; the longest is the Onyx.
